Magnetic-Order-Driven Nonlinear Photocurrents in PT-Broken Antiferromagnetic MnS2 and Altermagnetic MnSe2
Fu Li, Rajyavardhan Ray, Xiaoxiong Liu +6
Nonlinear photocurrent responses generally require inversion-symmetry breaking, but its origin can be magnetic rather than structural. In this study, we investigate the bulk photov…
Frustration-induced multiferroicity in hauerite MnS2
Vilmos Kocsis, Harish K. Singh, Kranthi K. Bestha +4
Pyrite-type mineral hauerite MnS is a magnetic insulator with localized moments. Below 48 K, it develops a collinear antiferromagnetic order, accompanied by unit-ce…
Anomalous Hall effect and magnetoresistance in micro-ribbons of the magnetic Weyl semimetal candidate PrRhC2
Mickey Martini, Helena Reichlova, Laura T. Corredor +10
PrRhC2 belongs to the rare-earth carbides family whose properties are of special interest among topological semimetals due to the simultaneous breaking of both inversion and time-r…
Real-space topological localizer index to fully characterize the dislocation skin effect
Nisarg Chadha, Ali G. Moghaddam, Jeroen van den Brink +1
The dislocation skin effect exhibits the capacity of topological defects to trap an extensive number of modes in two-dimensional non-Hermitian systems. Similar to the corresponding…
RIXS interferometry and the role of disorder in the quantum magnet BaTiIrO
M. Magnaterra, M. Moretti Sala, G. Monaco +8
Motivated by several claims of spin-orbit driven spin-liquid physics in hexagonal BaTiIrO hosting Ir2O9 dimers, we report on resonant inelastic x-ray scattering…
Symmetry induced selective excitation of topological states in SSH waveguide arrays
Min Tang, Jiawei Wang, Sreeramulu Valligatla +10
The investigation of topological state transition in carefully designed photonic lattices is of high interest for fundamental research, as well as for applied studies such as manip…
