Fractionalization from Kinetic Frustration in Doped Two-Dimensional SU(4) Quantum Magnets
Wilhelm Kadow, Ivan Morera, Eugene Demler +1
Separating electrons into emergent fractional quasiparticles is a hallmark of exotic quantum phases of matter with strong interactions. Understanding under which circumstances frac…
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…
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…
Kondo impurity in an attractive Fermi-Hubbard bath: Equilibrium and dynamics
Zhi-Yuan Wei, Tao Shi, J. Ignacio Cirac +1
We investigate theoretically equilibrium and dynamical properties of a Kondo impurity coupled to either 1D or 2D superconductors, modeled by the attractive Fermi-Hubbard model. By…
Spectroscopy of Hubbard-Mott excitons and their ro-vibrational excitations
Annabelle Bohrdt, Eugene Demler, Fabian Grusdt
Hubbard excitons are bound states of doublons and holes that can be experimentally probed both in real materials, such as cuprates, and in cold atom quantum simulators. Here we com…
