Unifying static and dynamic properties in 3D quantum antiferromagnets
H. D. Scammell, Y. Kharkov, Yan Qi Qin +3
Quantum Monte Carlo simulations offer an unbiased means to study the static and dynamic properties of quantum critical systems, while quantum field theory provides direct analytica…
Strain-gradient-induced magnetic anisotropy in straight-stripe mixed-phase bismuth ferrites: An insight into flexomagnetic phenomenon
Jin Hong Lee, Kwang-Eun Kim, Byung-Kweon Jang +7
Implementation of antiferromagnetic compounds as active elements in spintronics has been hindered by their insensitive nature against external perturbations which causes difficulti…
Bound states of skyrmions and merons near the Lifshitz point
Y. A. Kharkov, O. P. Sushkov, M. Mostovoy
We study topological defects in anisotropic ferromagnets with competing interactions near the Lifshitz point. We show that skyrmions and bi-merons are stable in a large part of the…
Multiple universalities in order-disorder magnetic phase transitions
H. D. Scammell, O. P. Sushkov
Phase transitions in isotropic quantum antiferromagnets are associated with the condensation of bosonic triplet excitations. In three dimensional quantum antiferromagnets, such as…
