Quantized single-particle Thouless pump induced by topology transfer from a Chern insulator at finite temperature
Lukas Wawer, Razmik Unanyan, Michael Fleischhauer
Quantized particle or spin transport upon cyclic parameter variations, determined by topological invariants, is a key signature of Chern insulators in the ground state. While measu…
Stimulated-Raman-Adiabatic-Passage mechanism in a magnonic environment
Qi Wang, Thomas Brächer, Michael Fleischhauer +2
We discuss the realization of a magnonic version of the STImulated-Raman-Adiabatic-Passage (m-STIRAP) mechanism using micromagnetic simulations. We consider the propagation of magn…
Chern number and Berry curvature for Gaussian mixed states of fermions
Lukas Wawer, Michael Fleischhauer
We generalize the concept of topological invariants for mixed states based on the ensemble geometric phase (EGP) introduced for one-dimensional lattice models to two dimensions. In…
Polaron Interactions and Bipolarons in One-Dimensional Bose Gases in the Strong Coupling Regime
Martin Will, Gregory E. Astrakharchik, Michael Fleischhauer
Bose polarons, quasi-particles composed of mobile impurities surrounded by cold Bose gas, can experience strong interactions mediated by the many-body environment and form bipolaro…
