Introduction
Fabrizio Pinto received an Enrico Persico scholarship from the Accademia Nazionale dei Lincei and a Laurea in physics cum laude from the University of Rome, La Sapienza. He obtained his PhD from Brigham Young University with a Sigma-Xi award-winning dissertation on globular clusters and gravitational N-body supercomputer applications. Dr. Pinto left academia to join the NASA Jet Propulsion Laboratory at Caltech. Later, as a California entrepreneur, he focused on Casimir forces obtaining patents in the US, the EU, and Japan. Again an academic, he investigates breakthrough dispersion force-enabled nanodevice spacecraft applications, tracks satellites, studies spacetime structure, and writes on the history of science. Dr. Pinto is a fixed wing, multi-engine instrument rated private pilot.

Article
Full-text available
The parallel development of the theories of electrodynamical and gravitational dispersion forces reveals important differences. The former arose earlier than the formulation of quantum electrodynamics so that expressions for the unretarded, van der Waals forces were obtained by treating the field as classical. Even after the derivation of quantum e...
Article
In this paper, dispersion forces between neutrons are suggested as a probe of the fundamental structure of spacetime. Corrections to standard expressions for the interparticle potentials are obtained through computer algebra system strategies and a novel heuristic argument for comparison with field theory computations. It is confirmed that, to firs...

Chapter
Suggestions that Casimir forces represent a remarkable—specifically, disruptive—technological opportunity either to enhance the performance of existing devices or even to introduce capabilities entirely inaccessible to traditional approaches were initially received with caution and even skepticism particularly by some within the theoretical physics...
Chapter
Seventy years after submission to the Physical Review of the crucial quantum electrodynamical treatment of interatomic dispersion forces by Casimir and Polder, our understanding of such interactions in both the unretarded and retarded regimes has undergone a dramatic and intricate evolution. In this contribution, we explore the ultimate physical mo...
Article
Several experimental detections have demonstrated the existence of Borromean states predicted by Vitaly Efimov within a nuclear physics context, that is, trimers bound despite the absence of bound states of any of the two-body subsystems. I show that novel Efimov Physics is expected in gravitationally polarizable nonbaryonic dark matter beyond the...
Article
Full-text available
It has been predicted that, if gravitational wave reflectors exist, two such parallel plane gravitational mirrors separated by an empty gap will interact not only via the well-known Casimir effect of quantum electrodynamics but also because of an analogous gravitational Casimir force. It has been further claimed that this phenomenon would demonstra...
Article
Full-text available
In this Invited paper, we begin by a historical introduction to provide a motivation for the classical problems of interatomic force computation and associated challenges. This analysis will lead us from early theoretical and experimental accomplishments to the integration of these fascinating interactions into the operation of realistic, next-gene...
Conference Paper
The measurement of Casimir forces by means of condenser microphones has been shown to be quite promising since its early introduction almost half-a-century ago. However, unlike the remarkable progress achieved in characterizing the vibrating membrane in the dynamical case, the accurate determination of the membrane static figure under electrostatic...
Article
Full-text available
Two infinite parallel plane slabs separated by a gap alter the zero-point-energy of the matter-electromagnetic field system. Generally speaking, the corresponding interaction depends on the reflection properties of the boundaries, and therefore on the dielectric functions of both the slab and gap materials, on the gap width, and on the absolute tem...
Chapter
A novel approach leading to potentially extremely high-density energy and power storage is proposed based upon the energy exchange between the dispersion force field in an assembly of aligned telescoping nanotubes and the electrostatic field produced by an external voltage source biasing such nanostructures with respect to a facing electrode. We sh...
Article
It is shown by means of the optical medium analogy that the static Casimir force between two conducting plates is modulated by gravitational waves. The magnitude of the resulting force changes within the range of already existing small force metrology. It is suggested to enhance the effects on a Casimir force oscillator by mechanical parametric amp...
Article
A nearby atom interacts with these charges, thereby producing a field that propagates back to the original atom. Finally in the 1930s this approach was fully analyzed by German-American physicist Fritz London. Additionally, London proposed that dispersion forces are additive, so that the total force between two objects should be the sum of all forc...
Article
A model of exciton screening by photo-generated free charges in semiconducting single-walled carbon nanotubes is considered to interpret recent data from the only experiment on this phenomenon reported in the literature. The potential of electron-hole interactions on the nanotube surface is computed starting from the derived full two-dimensional ex...
Conference Paper
Here we show for the first time that the van der Waals forces which act on the inner cores of multiwalled nanotubes can be altered to produce high-energy, high-luminosity neutral beams of nano-shuttles sliding inside the outer shells until they are ejected. This novel principle of nanotube core acceleration is based on a nanoscale implementation of...
Article
We present an improved demonstration of the calculation of Casimir forces in one-dimensional systems based on the recently proposed numerical imaginary frequency Green’s function computation approach. The dispersion force on two thick lossy dielectric slabs separated by an empty gap and placed within a perfectly conducting cavity is obtained from t...
Article
The feasibility to carry out the contactless actuation and control of both continuous facesheet deformable mirrors and MOEMS segmented micromirrors by manipulating van der Waals forces between electrically neutral surfaces is discussed. As we show, appropriately engineering such surface forces allows for adaptive optics strategies that are fully sc...
Article
In our laboratory, we have been developing a practical demonstration of actuation by means of the Casimir force inspired by the capacitive detection approach originally described by Arnold, Hunklinger and Dransfeld (1972 Rev. Sci. Instrum. 43 584–7). In this paper, we first describe the mathematical challenges pertaining to the electrostatic calibr...
Article
As micro-electro-mechanical system (MEMS) fabrication continues on an ever-decreasing scale, new technological challenges must be successfully negotiated if Moore's Law is to be an even approximately valid model of the future of device miniaturization. Among the most significant obstacles is the existence of strong surface forces related to quantum...
Article
An ongoing proof‐of‐concept demonstration of the resonant actuation of a thin membrane by periodic van der Waals forces between an illuminated semiconducting layer and a vibrating sensing element is reported. In the first phase of our effort, we have studied the mechanical response of a microphone membrane modified by a central rigid silica disk un...
Article
The problem of two unequal electrodes within a shielding cavity in the presence of a dielectric partially filling the gap is treated by means of overrelaxation methods in the axisymmetric case. A discrepancy in the literature concerning the boundary equation between two dielectrics is resolved and the difference equation for the dielectric corner p...
Article
It is shown that, by arranging the atoms in a Bose-Einstein condensate gas within an optical lattice, it is possible to directly verify experimentally that the van der Waals potential energy contributes an effective change to the gravitational mass of the atoms trapped in the array sites equal to that predicted by Einstein's mass-energy equivalency...
Article
The fundamental principles of a realistic thrusting system based on dispersion force engineering in curved spacetime are presented. After an introduction to place van der Waals and Casimir force applications to technology in their proper context, the Laplace equation of elementary electrostatics for a single charge is generalized in the presence of...
Article
It is an early result of electrostatics in curved space that the gravitational mass of a charge distribution changes by an amount equal to Ues/c2, where Ues is the internal electrostatic potential energy and c is the speed of light, if the system is supported at rest by external forces. This fact, independently rediscovered in recent years in the c...
Article
The natural frequencies of a membrane-central core system are computed and compared with the experimental data from a modified capacitive microphone excited by an electrostatic actuator in a vacuum chamber under controlled temperature conditions. The observed frequencies confirm those from the theoretical model to within ≲2%.
Article
In the typical Casimir effect, the boundaries of two semi-infinite media exert a force upon one another across a vacuum gap separating them. In this paper, I argue that a static gravitational field can be regarded as a ``soft'' boundary which interacts with a test object of finite size through the electromagnetic zero-point-energy field. Therefore,...
Article
An idealized system composed of two parallel, semiconducting boundaries separated by an empty gap of variable width is considered. A gedanken experiment is discussed to show that, in general, the total work done by the Casimir force along a closed path that includes appropriate transformations does not vanish. It is shown that, in the limit of an e...

Motivated by the upcoming launch of the solar electric propulsion mission New Millennium Deep Space 1, an analysis of the operational navigation strategies affecting ground based, deep space orbit determination of low thrust missions is addressed. Simulations are performed to assess strategies for radiometric based calibration of the SEP engine. Co...
Article
We show that highly excited Rydberg atoms nearby astrophysical gravitational wave sources are expected to emit significant electromagnetic radiation in the radio through a process of gravitationally induced resonance fluorescence. Semiclassical arguments are discussed and a quantum-mechanical expression for the differential cross section is obtaine...

Article
The possible use of loosely bound Rydberg atoms for remote gravimetric measurements is explored. The first-order corrections to the nonrelativistic nS and nP states for n greater than 2 are obtained for the first time. A procedure to evaluate corrections of any order is outlined and applied to the 1S state in a spherical symmetry. It is shown that...
Article
The formation of globular clusters was a key cosmological process related to the physical state of the universe shortly after the Big Bang. For this reason, globular clusters can be used as probes to study the environments where galaxies formed, and in order to better understand the formation of these objects, the problem was approached from two di...
Article
Full-text available
A model is presented and discussed in order to investigate how the dynamical properties of a young globular cluster depend on the details of the process of formation. Several parameters are constrained by applying the model to some massive associations. Values of a number of observables are obtained. The approach provided in the paper shows how, qu...
Article
Full-text available
The problem of change of radius of a dynamical system which suffers mass loss is addressed in the impulsive approximation. The results are framed into the general scenario of star-cluster formation. It is shown that the expansion factor Rcl/R0 is not only a function of star formation efficiency ɛ, as in Hills (1980), but also of initial gas turbule...
