Dissipative dynamics of an impurity with spin-orbit coupling
Areg Ghazaryan, Alberto Cappellaro, Mikhail Lemeshko +1
Brownian motion of a mobile impurity in a bath is affected by spin-orbit coupling (SOC). Here, we discuss a Caldeira-Leggett-type model that can be used to propose and interpret qu…
Magnetic impurity in a one-dimensional few-fermion system
Lukas Rammelmüller, David Huber, Matija Čufar +3
We present a numerical analysis of spin- fermions in a one-dimensional harmonic potential in the presence of a magnetic point-like impurity at the center of the trap.…
Effective model for studying optical properties of lead-halide perovskites
Artem G. Volosniev, Abhishek Shiva Kumar, Dusan Lorenc +5
We use general symmetry-based arguments to construct an effective model suitable for studying optical properties of lead-halide perovskites. To build the model, we identify an atom…
Spin-Electric Coupling in Lead Halide Perovskites
Artem G. Volosniev, Abhishek Shiva Kumar, Dusan Lorenc +5
Lead-halide perovskites enjoy a number of remarkable optoelectronic properties. To explain their origin, it is necessary to study how electromagnetic fields interact with these sys…
A modular implementation of an effective interaction approach for harmonically trapped fermions in 1D
Lukas Rammelmüller, David Huber, Artem G. Volosniev
We introduce a generic and accessible implementation of an exact diagonalization method for studying few-fermion models. Our aim is to provide a testbed for the newcomers to the fi…
Artificial atoms from cold bosons in one dimension
Fabian Brauneis, Timothy G Backert, Simeon I Mistakidis +3
We investigate the ground-state properties of weakly repulsive one-dimensional bosons in the presence of an attractive zero-range impurity potential. First, we derive mean-field so…
