Connecting single-layer - to Kondo lattice models: Exploration with cold atoms
Hannah Lange, Eugene Demler, Jan von Delft +2
The Kondo effect, a hallmark of many-body physics, emerges from the antiferromagnetic coupling between localized spins and conduction fermions, leading to a correlated many-body si…
Anomalous Eigenstates of a Doped Hole in the Ising Antiferromagnet
Piotr Wrzosek, Krzysztof Wohlfeld, Eugene A. Demler +2
The problem of a mobile hole doped into an antiferromagnet Mott insulator is believed to underly the rich physics of several paradigmatic strongly correlated electron systems, rang…
Variational approach to the dynamics of dissipative quantum impurity models
Yi-Fan Qu, Martino Stefanini, Tao Shi +4
Recent experiments with quantum simulators using ultracold atoms and superconducting qubits have demonstrated the potential of controlled dissipation as a versatile tool for realiz…
Dissipative realization of Kondo models
Martino Stefanini, Yi-Fan Qu, Tilman Esslinger +3
We demonstrate that the Kondo effect can be induced through non-linear dissipative channels, without requiring any coherent interaction on the impurity site. Specifically, we consi…
Subgap pumping of antiferromagnetic Mott insulators: photoexcitation mechanisms and applications
Radu Andrei, Mingyao Guo, Mustafa Ali +4
We study the behavior of the 2D repulsive Hubbard model on a square lattice at half filling, under strong driving with ac electric fields, by employing a time-dependent Gaussian va…
Bipolaron dynamics in the one-dimensional SSH model
Filip MarijanoviÄ, Yi-Fan Qu, Eugene Demler
Characterizing bipolaron binding, and understanding how it depends on electron-phonon interaction, is crucial to unraveling the nature of emergent many-body states in strongly inte…
