Path integral description of combined Hamiltonian and non-Hamiltonian dynamics in quantum dissipative system
A. M. Barth, A. Vagov, V. M. Axt
We present a numerical path-integral iteration scheme for the low dimensional reduced density matrix of a time-dependent quantum dissipative system. Our approach simultaneously acc…
The BCS-BEC crossover induced by a shallow band: Pushing standard superconductivity types apart
S. Wolf, A. Vagov, A. A. Shanenko +3
It is well-known that the appearance of almost-empty (shallow) conduction bands in solids strongly affects their superconducting properties. In a shallow band charge carriers are d…
Shallow-band superconductors: pushing superconductivity types apart
S. Wolf, A. Vagov, A. A. Shanenko +2
Magnetic response is a fundamental property of superconducting materials, which helps to distinguish two superconductivity types: the ideally diamagnetic type I and type II, which…
Fast and selective phonon-assisted state preparation of a quantum dot by adiabatic undressing
A. M. Barth, S. Lüker, A. Vagov +3
We investigate theoretically the temporal behavior of a quantum dot under off-resonant optical excitation targeted at fast acoustic phonon-assisted state preparation. We demonstrat…
