Stability of ferroelectric bubble domains
Vivasha Govinden, Suyash Rijal, Qi Zhang +4
Nanoscale ferroelectric topologies such as vortices, anti-vortices, bubble patterns etc. are stabilized in thin films by a delicate balance of both mechanical and electrical bounda…
Electrocaloric effects in multiferroics
Zhijun Jiang, Bin Xu, Sergey Prosandeev +4
An atomistic effective Hamiltonian is used to compute electrocaloric (EC) effects in rare-earth substituted BiFeO multiferroics. A phenomenological model is then developed to…
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…
Atomic Scale Measurement of Polar Entropy
Debangshu Mukherjee, Sergei Prokhorenko, Leixin Miao +4
Entropy is a fundamental thermodynamic quantity that is a measure of the accessible microstates available to a system, with the stability of a system determined by the magnitude of…
