Controlling charge and spin currents through nonreciprocal dissipative processes
Catalin-Mihai Halati, Jean-Sébastien Bernier
We investigate the generation and control of both charge and spin currents via nonreciprocal dissipative mechanisms in a two-dimensional spinful fermionic atom quantum system with…
Experimental observation of repulsively bound magnons
Zhe Wang, Catalin-Mihai Halati, Jean-Sébastien Bernier +9
Stable composite objects, such as hadrons, nuclei, atoms, molecules and superconducting pairs, formed by attractive forces are ubiquitous in nature. By contrast, composite objects…
Repulsively bound magnon excitations of a spin-1/2 XXZ chain in a staggered transverse field
Catalin-Mihai Halati, Zhe Wang, Thomas Lorenz +2
We study the excitation spectrum of the one-dimensional spin-1/2 XXZ chain with antiferromagnetic Ising anisotropy across a magnetic quantum phase transition induced by the applica…
Radio-frequency driving of an attractive Fermi gas in a one-dimensional optical lattice
Johannes Kombe, Michael Köhl, Corinna Kollath +1
We investigate the response to radio-frequency driving of an ultracold gas of attractively interacting fermions in a one-dimensional optical lattice. We study the system dynamics b…
Decay and revival of a transient trapped Fermi condensate
Timothy Harrison, Martin Link, Alexandra Behrle +6
We study experimentally and theoretically the response of a two-component Fermi condensate in the strongly-interacting regime to a quench of the interaction strength. The quench is…
Melting of the critical behavior of a Tomonaga-Luttinger liquid under dephasing
Jean-Sebastien Bernier, Ryan Tan, Chu Guo +2
Strongly correlated quantum systems often display universal behavior as, in certain regimes, their properties are found to be independent of the microscopic details of the underlyi…
