Adiabatic realization of anomalous Floquet topological systems
Luca Asteria, Marcel N. Kosch, Henrik P. Zahn +4
Topology has emerged as a central concept for classifying phases of matter. The situation is especially rich in periodically driven systems, where anomalous Floquet topological pha…
Adiabatic preparation of a fractional quantum Hall fluid by coherently pumping atoms from a Bose-Einstein condensate
Alberto Tabarelli de Fatis, Christof Weitenberg, Alexander Schnell +2
We propose a protocol to adiabatically prepare a many-particle fractional quantum Hall fluid of bosonic ultracold atoms exploiting a time-dependent coherent coupling of a strongly…
Micromotion area as proxy for anomalous Floquet topological systems
Luca Asteria, Klaus Sengstock, André Eckardt +1
Driven Floquet systems can realize topological phases with no static counterparts. These so-called anomalous Floquet topology breaks the bulk-boundary correspondence based on the C…
Revealing Pseudo-Fermionization and Chiral Binding of One-Dimensional Anyons using Adiabatic State Preparation
Brice Bakkali-Hassani, Joyce Kwan, Perrin Segura +5
Fractional statistics give rise to quantum behaviors that differ fundamentally from those of bosons and fermions. While two-dimensional anyons play a major role in strongly correla…
Quantum geometry of bosonic Bogoliubov quasiparticles
Isaac Tesfaye, André Eckardt
Bosonic Bogoliubov de Gennes (BBdG) Hamiltonians describe the excitations of weakly interacting Bose condensates as well as photonic systems under parametric driving. Their topolog…
Effective (Floquet) Lindblad generators from spectral unwinding
Görkem D. Dinc, André Eckardt, Alexander Schnell
A mathematical description of the reduced dynamics of an open quantum system can often be given in terms of a completely positive and trace preserving (CPTP) map, also known as qua…
