Vanishing Hall Response of Charged Fermions in a Transverse Magnetic Field
Michele Filippone, Charles-Edouard Bardyn, Sebastian Greschner +1
We study the Hall response of quasi-two-dimensional lattice systems of charged fermions under a weak transverse magnetic field, in the ballistic coherent limit. We identify a setup…
Bulk Pumping in 2D Topological Phases
Charles-Edouard Bardyn, Michele Filippone, Thierry Giamarchi
The notion of topological (Thouless) pumping in topological phases is traditionally associated with Laughlin's pump argument for the quantization of the Hall conductance in two-dim…
Steady state of interacting Floquet insulators
Karthik I. Seetharam, Charles-Edouard Bardyn, Netanel H. Lindner +2
Floquet engineering offers tantalizing opportunities for controlling the dynamics of quantum many body systems and realizing new nonequilibrium phases of matter. However, this appr…
A recipe for topological observables of density matrices
Charles-Edouard Bardyn
Meaningful topological invariants for mixed quantum states are challenging to identify as there is no unique way to define them, and most choices do not directly relate to physical…
Controlled parity switch of persistent currents in quantum ladders
Michele Filippone, Charles-Edouard Bardyn, Thierry Giamarchi
We investigate the behavior of persistent currents for a fixed number of noninteracting fermions in a periodic quantum ladder threaded by Aharonov-Bohm and transverse magnetic flux…
Probing the topology of density matrices
Charles-Edouard Bardyn, Lukas Wawer, Alexander Altland +2
The mixedness of a quantum state is usually seen as an adversary to topological quantization of observables. For example, exact quantization of the charge transported in a so-calle…
