An electron-phonon system at commensurate filling often displays charge order (CO) in the ground state. Such a system subject to a laser pulse shows a wide variety of behaviour. A weak pulse sets up low amplitude oscillations in the order parameter, with slow decay to a slightly suppressed value. A strong pulse leads to the destruction of the charg...

Machine learning models are developed to hierarchically filter and select stable magnetic mate- rials with large magnetization and magnetic anisotropy energy. Starting from an initial set of 278 materials, 10...

We use a Langevin dynamics approach to map out the thermal phases of an antiferromagnetic Mott insulator pushed out of equilibrium by a large voltage bias. The Mott insulator is realised in the half-filled Hubbard model in a three dimensional bar geometry with leads at voltage $\pm V/2$ connected at the two ends. We decouple the strong Hubbard inte...
Article
We develop a real-space theory of the voltage bias driven transition from a Mott insulator to a correlated metal. Within our Keldysh mean-field approach the problem reduces to a self-consistency scheme for the charge and spin profiles in this open system. We solve this problem for a two dimensional antiferromagnetic Mott insulator at zero temperatu...

We investigate the thermal physics of a Bose-Hubbard model with Rashba spin-orbit coupling starting from a strong coupling mean-field ground state. The essential role of the spin-orbit coupling γ is to promote condensation of the bosons at a finite wave vector k0. We find that the bosons display either homogeneous or phase-twisted or orbital ordere...

We investigate the thermal physics of a Bose-Hubbard model with Rashba spin-orbit coupling starting from a strong coupling mean-field ground state. The essential role of the spin-orbit coupling $\left(\gamma\right)$ is to promote condensation of the bosons at a finite wavevector ${k}_{0}$. We find that the bosons display either homogeneous or phase...

We develop a real space picture of the voltage bias driven transition from a Mott insulator to a correlated metal. Within our Keldysh mean field approach the problem reduces to self-consistency equations for the charge and spin auxiliary fields that decouple the Hubbard interaction. We solve these, obtain the nonlinear current-voltage (I-V) charact...
