Realizing Altermagnetism in Fermi-Hubbard Models with Ultracold Atoms
Purnendu Das, Valentin Leeb, Johannes Knolle +1
Altermagnetism represents a type of collinear magnetism, that is in some aspects distinct from ferromagnetism and from conventional antiferromagnetism. In contrast to the latter, s…
Deconfinement Dynamics of Fractons in Tilted Bose-Hubbard Chains
Julian Boesl, Philip Zechmann, Johannes Feldmeier +1
Fractonic constraints can lead to exotic properties of quantum many-body systems. Here, we investigate the dynamics of fracton excitations on top of the ground states of a one-dime…
Deconfined Quantum Criticality in the long-range, anisotropic Heisenberg Chain
Anton Romen, Stefan Birnkammer, Michael Knap
Deconfined quantum criticality describes continuous phase transitions that are not captured by the Landau-Ginzburg paradigm. Here, we investigate deconfined quantum critical points…
Realizing Topological Superconductivity in Tunable Bose-Fermi Mixtures with Transition Metal Dichalcogenide Heterostructures
Caterina Zerba, Clemens Kuhlenkamp, Ataç Imamoğlu +1
Heterostructures of two-dimensional transition metal dichalcogenides (TMDs) are emerging as a promising platform for investigating exotic correlated states of matter. Here, we prop…
Signatures of Domain-Wall Confinement in Raman Spectroscopy of Ising Spin Chains
Stefan Birnkammer, Johannes Knolle, Michael Knap
Mesonic bound states of domain walls can be stabilized in quasi one-dimensional magnetic compounds. Here, we theoretically study the Raman light scattering response of a twisted Ki…
Single-hole spectra of Kitaev spin liquids: from dynamical Nagaoka ferromagnetism to spin-hole fractionalization
Wilhelm Kadow, Hui-Ke Jin, Johannes Knolle +1
The dynamical response of a quantum spin liquid upon injecting a hole is a pertinent open question. In experiments, the hole spectral function, measured momentum-resolved in angle-…
Kinetic Ferromagnetism and Topological Magnons of the Hole-Doped Kitaev Spin Liquid
Hui-Ke Jin, Wilhelm Kadow, Michael Knap +1
We study the effect of hole doping on the Kitaev spin liquid (KSL) and find that for ferromagnetic (FM) Kitaev exchange the system is very susceptible to the formation of a FM…
