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…
