Berezinskii-Kosterlitz-Thouless Phase in Two-dimensional Ferroelectrics
Changsong Xu, Yousra Nahas, Sergei Prokhorenko +2
The celebrated Berezinskii-Kosterlitz-Thouless (BKT) phase transition refers to a topological transition characterized, e.g., by the dissociation of vortex-antivortex pairs in two-…
Possible Kitaev Quantum Spin Liquid State in 2D Materials with S=3/2
Changsong Xu, Junsheng Feng, Mitsuaki Kawamura +6
Quantum spin liquids (QSLs) form an extremely unusual magnetic state in which the spins are highly correlated and fluctuate coherently down to the lowest temperatures, but without…
Magnetic Skyrmion State in Janus Monolayers of Chromium Trihalides Cr(I,X)3
Changsong Xu, Junsheng Feng, Hongjun Xiang +1
Magnetic skyrmions are nano-scale spin structures that are promising for ultra-dense memory and logic devices. Recent progresses in two-dimensional magnets encourage the idea to re…
Density functional perturbation theory within non-collinear magnetism
Fabio Ricci, Sergei Prokhorenko, Marc Torrent +2
We extend the density functional perturbation theory formalism to the case of non-collinear magnetism. The main problem comes with the exchange-correlation (XC) potential derivativ…
Electrocaloric effects in the lead-free Ba(Zr,Ti)O relaxor ferroelectric from atomistic simulations
Zhijun Jiang, Sergei Prokhorenko, Sergey Prosandeev +5
Atomistic effective Hamiltonian simulations are used to investigate electrocaloric (EC) effects in the lead-free Ba(ZrTi)O (BZT) relaxor ferroelectric. We fin…
