Magnetic circular dichroism of THz modes and selection rules of Raman-active optical phonons in the polar altermagnet candidate \ce{Mn2Mo3O8}
F. Schilberth, K. Vasin, M. Knauft +14
We investigated the magnetic and vibrational excitations in the collinear altermagnet candidate \ce{Mn2Mo3O8} by temperature dependent Raman scattering and magneto-optical THz time…
Chiral enhancement of two-magnon bound states in an triangular-lattice magnet
László Rudner, Karlo Penc
We study one- and two-magnon excitations above the fully polarized state of the spin- triangular-lattice -- Heisenberg model with an additional uniform scalar-c…
Evidence for a Dirac spin liquid in the generalized Shastry-Sutherland model
Atanu Maity, Francesco Ferrari, Sylvain Capponi +8
We present a multimethod investigation into the nature of the recently reported quantum spin liquid (QSL) phase in the spin- Heisenberg antiferromagnet on the Shastry-Sutherla…
Classical Kitaev model in a magnetic field
Paul A. McClarty, Roderich Moessner, Karlo Penc +1
Motivated by experiments on spin-orbit coupled magnets with Kitaev exchange in magnetic fields, we present an analysis of the classical Kitaev honeycomb model in the presence of a…
Semi-Dirac spin liquids and frustrated quantum magnetism on the trellis lattice
Sourin Chatterjee, Atanu Maity, Janik Potten +7
Geometrical frustration in quantum magnets provides a fertile setting for unconventional phases of matter, including quantum spin liquids (QSLs). The trellis lattice, with its comp…
Spin Liquid Landscapes in the Kagome Lattice: A Variational Monte Carlo Study of the Chiral Heisenberg Model and Experimental Signatures
Hee Seung Kim, Hyeok-Jun Yang, Karlo Penc +1
Chiral spin liquids, which break time-reversal symmetry, are of great interest due to their topological properties and fractionalized excitations (anyons). In this work, we investi…
