In this work, we study a prototypical, experimentally accessible scenario that enables the systematic generation of so-called high-order rogue waves in atomic Bose-Einstein condensates. These waveforms lead to significantly and controllably more extreme focusing events than the famous Peregrine soliton. In one spatial dimension, we showcase conclus...

In this report, we develop analytical models and implement numerical schemes to represent a coupled mechanical system of deflections and stresses in beams joined together by a continuous spring layer. We begin by considering a one-dimensional and uniform rectangular beam resting on a continuous layer of elastic material coupled with another rectang...

Tikhonov regularization is a common technique used when solving poorly behaved optimization problems. Often, and with good reason, this technique is applied by practitioners in an ad hoc fashion. In this note, we systematically illustrate the role of Tikhonov regularizations in two simple, yet instructive examples. In one example, we use regular pe...

We address the problem of how to best manage a limited partner’s capital commitments to various vintages of private equity funds in order to achieve a desired target level of exposure. We adopt and extend the Yale modeling framework by accounting for dynamical noise on the fund returns with both systematic and idiosyncratic components assumed indep...

We provide an optimal control framework for efficiently coupling light in a bare fiber into Bragg gratings with an appreciable Kerr nonlinearity. The light-grating interaction excites gap solitons, a type of localized nonlinear coherent state which propagates with a central frequency in the forbidden band gap, resulting in a dramatically slower gro...

We pose the problem of transferring a Bose-Einstein Condensate (BEC) from one side of a double-well potential to the other as an optimal control problem for determining the time-dependent form of the potential. We derive a reduced dynamical system using a Galerkin truncation onto a finite set of eigenfunctions and find that including three modes su...

We address the problem of reshaping light in the Schrödinger optics regime from the perspective of the optimal control theory. In technological applications, Schrödinger optics is often used to model a slowly varying amplitude of a para-axially propagating electric field where the square of the waveguide’s index of refraction is treated as the pote...

Applications of Bose-Einstein condensates (BEC) often require that the condensate be prepared in a specific complex state. Optimal control is a reliable framework to prepare such a state while avoiding undesirable excitations, and, when applied to the time-dependent Gross-Pitaevskii equation (GPE) model of BEC in multiple space dimensions, results...
