Strong coupling of lattice and orbital excitations in quantum magnet CaCrO: Anomalous temperature dependence of Raman phonons
Srishti Pal, Arnab Seth, Anzar Ali +4
We report low-temperature Raman signatures of the Heisenberg quantum magnet CaCrO, showing clear anomalies in phonon mode frequencies and linewidths below 1…

Probing emergent QED in quantum spin ice via Raman scattering of phonons: shallow inelastic scattering and pair production
Arnab Seth, Subhro Bhattacharjee, Roderich Moessner
We present a new mechanism for Raman scattering of phonons, which is based on the linear magnetoelastic coupling present in non-Kramers magnetic ions. This provides a direct coupli…

Probing signatures of fractionalization in candidate quantum spin liquid Cu2IrO3 via anomalous Raman scattering
Srishti Pal, Arnab Seth, Piyush Sakrikar +5
Long-range entanglement in quantum spin liquids (QSLs) lead to novel low energy excitations with fractionalised quantum numbers and (in 2D) statistics. Experimental detection and m…
