Floquet systems coupled to particle reservoirs

Stochastic many-particle systems far from equilibrium coupled to bulk reservoirs

Classical driven transport in open systems with particle interactions and general couplings to reservoirs.

We study nonequilibrium steady states of lattice gases with nearest-neighbor interactions that are driven between two reservoirs. Density profiles in these systems exhibit oscillations close to the reservoirs. We demonstrate that an approach based on time-dependent density functional theory copes with these oscillations and predicts phase diagrams of bulk densities to a good approximation under...

Transport calculation of semiconductor nanowires coupled to quantum well reservoirs

Semiconductor nanowires are possible candidates to replace the metal-oxide-semiconductor field-effect transistors (MOSFET) since they can act both as active devices or as device connectors. In this article, the transmission coefficients of Si and GaAs nanowires with arbitrary transport directions and cross sections are simulated in the nearestneighbor sp3d5s∗ semi-empirical tight-binding method...

Energetics of an rf SQUID Coupled to Two Thermal Reservoirs

We study energetics of a Josephson tunnel junction connecting a superconducting loop pierced by an external magnetic flux (an rf SQUID) and coupled to two independent thermal reservoirs of different temperature. In the framework of the theory of quantum dissipative systems, we analyze energy currents in stationary states. The stationary energy flow can be periodically modulated by the external ...

Floquet Theory for Mimo Sampled-data Systems

The paper transfers some classical results by Floquet from the theory of linear differential equations with periodically varying coefficients to MIMO sampleddata systems. The problem of modal control is formulated for sampled-data systems, and the general solution is given in a polynomial form.
