A new model for quantum dot light emitting-absorbing devices
Hagen Neidhardt, Lukas Wilhelm, Valentin Zagrebnov
Motivated by the Jaynes-Cummings (JC) model, we consider here a quantum dot coupled simultaneously to a reservoir of photons and to two electric leads (free-fermion reservoirs). Th…
Linear non-autonomous Cauchy problems and evolution semigroups
Hagen Neidhardt, Valentin A. Zagrebnov
The paper is devoted to the problem of existence of propagators for an abstract linear non-autonomous evolution Cauchy problem of hyperbolic type in separable Banach spaces. The pr…
The effect of time-dependent coupling on non-equilibrium steady states
Horia D. Cornean, Hagen Neidhardt, Valentin A. Zagrebnov
Consider (for simplicity) two one-dimensional semi-infinite leads coupled to a quantum well via time dependent point interactions. In the remote past the system is decoupled, and e…
