From stable periodic orbits to many-body chaos: doubly tunable prethermalization via engineering of an emergent band structure
Jianan Wang, Yang Hou, Andrea Pizzi +3
We uncover a family of many-body periodic orbits in a periodically driven (Floquet) spin system away from the high-frequency limit. While linear stability analysis predicts that pe…
Raman Circular Dichroism and Quantum Geometry of Chiral Quantum Spin Liquids
Eduard Koller, Valentin Leeb, Natalia B. Perkins +1
We show that the quantum geometry of fractionalized spin excitations in Mott-insulating quantum spin liquids (QSL) gives rise to a finite Raman circular dichroism (RCD) signal. We…
Intermediate Field Spin(on) Dynamics in -RuCl
C. L. Sarkis, K. D. Dixit, P. Rao +11
We present comprehensive inelastic neutron spectroscopic maps of the magnetic field-induced disordered phase of the Kitaev quantum spin liquid candidate material -RuCl. For…
Projectively implemented altermagnetism in an exactly solvable quantum spin liquid
Avedis Neehus, Achim Rosch, Johannes Knolle +1
Altermagnets are a new class of symmetry-compensated magnets with large spin splittings. Here, we show that the notion of altermagnetism extends beyond the realm of Landau-type ord…
Spin-lattice coupling induced chiral phonons and their signature in Raman Circular Dichroism
Eduard Koller, Swetlana Swarup, Johannes Knolle +1
Recent Raman experiments on the Kitaev material -RuCl have reported a finite Raman circular dichroism (RCD), revealing chiral phonon behaviour not expected from lattice sym…
Floquet Superheating
Yang Hou, Andrea Pizzi, Huike Jin +3
Periodically driven many-body systems generally heat towards a featureless 'infinite-temperature' state. As an alternative to uniform heating in a clean system, here we establish a…
