Charge-Conjugation Violation and Population Asymmetry in Bipartite Fermionic Lattices
Di Xiao, Xue-Ting Fang, Lushuai Cao +2
Charge conjugation violation (CCV) is a central concept in particle physics and appears also for quasiparticles in quantum many-body systems, which typically relies on an embedded…
Symmetry and integrability in the anyon-Hubbard model
Martin Bonkhoff, Grennon Gurney, Friethjof Theel +3
Recent cold atom experiments have realized one-dimensional anyons and enabled the tuning of 1D~statistics between bosons and fermions. Here, we analyze the symmetries, integrabilit…
Recurrence analysis of quantum many-body dynamics
Tomasz SzoÅdra, Matheus S. Palmero, Peter Schmelcher
Observables of out-of-equilibrium quantum many-body systems display complex temporal behavior that encodes the underlying physical mechanisms but typically resists straightforward…
The helical quantum two-body problem and its wave packet dynamics
Peter Schmelcher
We explore the helical quantum two-body problem i.e. two repulsively Coulomb interacting particles confined to move along a helix. The effective potential possesses a tunable numbe…
Mechanisms of localization in a finite harmonically confined optical superlattice
A. Katsaris, I. A. Englezos, C. Weitenberg +2
We investigate the impact of harmonic confinement in a finite optical superlattice and reveal the different mechanisms that can lead to the emergence of localized states. The optic…
-Continuum limit of bipartite lattices -- The SSH model
Fotios K. Diakonos, P. Schmelcher
We present a continuous non-local model that faithfully replicates the rich topological and spectral features of the Su-Schrieffer-Heeger (SSH) model. Remarkably, our model shares…
