Photogalvanic effect induced by an electric field

Spin polarization and dichroism effects induced by an electric field

We show that electric field can induce spin polarization and dichroism effects in angle resolved photoemission spectroscopy ARPES in spin orbit coupling systems. The physical origin behind the effects essentially is the same as the intrinsic spin Hall effect induced by the electric field. Since the ARPES experiments have both energy and momentum resolutions, the origin of the intrinsic spin Hal...

Study of leaky dielectric droplet behavior under an electric field: effect of viscosity and electric conductivity ratios

In this research, hydrodynamic behavior of a leaky dielectric droplet under an electric field is simulated. The level set method is used for interface tracking and the ghost fluid method is used for modeling discontinuous quantities at interface. Using Taylor’s leaky dielectric model, electric field and electric force at the interface is calculated. Simulation results show the droplet deformati...

Dimensional crossover driven by an electric field.

We study the steady-state dynamics of the Hubbard model driven out of equilibrium by a constant electric field and coupled to a dissipative heat bath. For a very strong field, we find a dimensional reduction: the system behaves as an equilibrium Hubbard model in lower dimensions. We derive steady-state equations for the dynamical mean-field theory in the presence of dissipation. We discuss how ...
