Temporal Berry Phase and the Emergence of Bose-Glass-Analog Phase in a Clean U(1) Superfluid
Ryuichi Shindou, Pengwei Zhao, Xiaonuo Fang
The (2+1)-dimensional U(1) sigma model with temporal Berry phase term captures zero-temperature phase-fluctuation-driven superfluid (SF) transitions in two spatial dimensions. From…
Long-distance spin transport in frustrated hyperkagome magnet Gd3Ga5O12
Di Chen, Bingcheng Luo, Lei Xu +17
Transport of spin angular momentum over large distance has been a long sought-after goal in the field of spintronics. While the majority of the research effort has been devoted to…
Simulational and theoretical studies of the Anderson transition in the chiral symmetry classes with weak topology
Shiyin Kuang, Tong Wang, Zhenyu Xiao +2
Combining lattice model simulations with a field theory study of effective theories, we investigate the nature of the Anderson transition in chiral symmetry classes with one-dimens…
Theory of the Anderson transition in three-dimensional chiral symmetry classes: Connection to type-II superconductors
Pengwei Zhao, Ryuichi Shindou
Phase transitions governed by topological defects constitute a cornerstone of modern physics. Two-dimensional (2D) Anderson transitions in chiral symmetry classes are driven by the…
Topological effect on order-disorder transitions in U(1) sigma models
Ryuichi Shindou, Pengwei Zhao
U(1) non-linear sigma model (NLSM) with a one-dimensional (1D) Berry phase is studied by a renormalization group theory. Order-disorder transition in U(1) NLSMs in -…
Fate of transient order parameter domain walls in ultrafast experiments
Lingxian Kong, Ryuichi Shindou, Zhiyuan Sun
In ultrafast experiments, an optical pump pulse often generates transient domain walls of the order parameter in materials with spontaneous symmetry breaking, due to either a finit…
