Latent Su-Schrieffer-Heeger models
Malte Röntgen, Xuelong Chen, Wenlong Gao +5
The Su-Schrieffer-Heeger (SSH) chain is the reference model of a one-dimensional topological insulator. Its topological nature can be explained by the quantization of the Zak phase…
Excited state preparation of trapped ultracold atoms via swept potentials
Daniel J. Bosworth, Maxim Pyzh, Peter Schmelcher
We study the out-of-equilibrium dynamics of non-interacting atoms confined within a one-dimensional harmonic trap triggered by dragging an external long-range potential through the…
Interaction-controlled impurity transport in trapped mixtures of ultracold bosons
Judith Becker, Maxim Pyzh, Peter Schmelcher
We explore the dynamical transport of an impurity between different embedding majority species which are spatially separated in a double well. The transfer and storage of the impur…
Breathing dynamics of the Bose polaron in a species-selective harmonic trap
Maxim Pyzh, Peter Schmelcher
We perform an extensive numerical study on the breathing dynamics of a few-body Bose polaron setup in a one-dimensional species-selective harmonic trap. The dynamics is triggered b…
On symmetries of a matrix and its isospectral reduction
Malte Röntgen, Maxim Pyzh, Christian V. Morfonios +1
The analysis of diagonalizable matrices in terms of their so-called isospectral reduction represents a versatile approach to the underlying eigenvalue problem. Starting from a symm…
Entangling lattice-trapped bosons with a free impurity: impact on stationary and dynamical properties
Maxim Pyzh, Kevin Keiler, Simeon I. Mistakidis +1
We address the interplay of few lattice trapped bosons interacting with an impurity atom in a box potential. For the ground state, a classification is performed based on the fideli…
