Elastocaloric effect of the heavy-fermion system YbPtBi
Elena Gati, Burkhard Schmidt, Sergey L. Bud'ko +2
YbPtBi is one of the heavy-fermion systems with largest Sommerfeld coefficient and is thus classified as a `super'-heavy fermion material. In this work, we resolve the long-deb…
Topological paramagnetic excitons of localized f electrons on the honeycomb lattice
Alireza Akbari, Burkhard Schmidt, Peter Thalmeier
We investigate the dispersive paramagnetic excitons on the honeycomb lattice that originate from the crystalline-electric field (CEF) split localized f-electron states in the param…
WaveTrain: A Python Package for Numerical Quantum Mechanics of Chain-Like Systems Based on Tensor Trains
Jerome Riedel, Patrick Gelß, Rupert Klein +1
WaveTrain is an open-source software for numerical simulations of chain-like quantum systems with nearest-neighbor (NN) interactions only. The Python package is centered around ten…
Quantum dynamics of coupled excitons and phonons in chain-like systems: tensor train approaches and higher-order propagators
Patrick Gelß, Sebastian Matera, Rupert Klein +1
We investigate tensor-train approaches to the solution of the time-dependent Schrödinger equation for chain-like quantum systems with on-site and nearest-neighbor interactions only…
Mapping atomic trapping in an optical superlattice onto the libration of a planar rotor in electric fields
Marjan Mirahmadi, Bretislav Friedrich, Burkhard Schmidt +1
We show that two seemingly unrelated problems - the trapping of an atom in an optical superlattice (OSL) and the libration of a planar rigid rotor in combined electric and optical…
Solving the time-independent Schrödinger equation for chains of coupled excitons and phonons using tensor trains
Patrick Gelß, Rupert Klein, Sebastian Matera +1
We demonstrate how to apply the tensor-train format to solve the time-independent Schrödinger equation for quasi one-dimensional excitonic chain systems with and without periodic b…
