Finite temperature electric field induced two-dimensional coherent nonlinear spectroscopy in a Kitaev magnet
Wolfram Brenig, Olesia Krupnitska
We study electric field induced two-dimensional coherent nonlinear optical spectroscopy (2DCS) in a Kitaev magnet at finite temperature. We show that 2DCS is susceptible to both ty…
Finite temperature second harmonic generation in Kitaev magnets
Olesia Krupnitska, Wolfram Brenig
We study electric field induced second harmonic generation (2HG) in the Kitaev model. This frustrated magnet hosts a quantum spin-liquid, featuring fractionalization in terms of mo…
Frustrated diamond-chain quantum Heisenberg antiferromagnet in a magnetic field
Johannes Richter, Olesia Krupnitska, Taras Krokhmalskii +1
We consider the antiferromagnetic spin-1/2 Heisenberg model on a frustrated diamond-chain lattice in a - or -aligned external magnetic field. We use the strong-coupling…
Semiquantitative theory for high-field low-temperature properties of a distorted diamond spin chain
Oleg Derzhko, Johannes Richter, Olesia Krupnitska
We consider the antiferromagnetic Heisenberg model on a distorted diamond chain and use the localized-magnon picture adapted to a distorted geometry to discuss some of its high-fie…
