From dimensional reduction to tetramerization in mixed ferro-antiferro breathing pyrochlores
Sourin Chatterjee, Kelvin Salou-Smith, Benedikt Schneider +8
We study the spin-1/2 nearest-neighbor Heisenberg model on the breathing pyrochlore lattice in the mixed ferro-antiferromagnetic regime, where one tetrahedral sublattice is antifer…
Chiral Color Ice: Exact Local Handedness Constraints and Möbius Zero Modes in Frustrated Magnets
Péter Kránitz, Yasir Iqbal, Karlo Penc
Local constraints govern the low-energy physics of frustrated matter, but familiar ice-type rules constrain flux-like quantities and are insensitive to handedness. Here we show tha…
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 a uniform scalar-chirality int…
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…
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…
Rigorous Anderson-type lower bounds on the ground-state energy of the pyrochlore Heisenberg antiferromagnet
Péter Kránitz, Karlo Penc
We construct rigorous Anderson-type lower bounds on the ground-state energy of the spin- Heisenberg antiferromagnet on the pyrochlore lattice. By formulating and optimizing a hi…
