Giant Magnetocaloric Effect in a High-Spin Shastry-Sutherland Dipolar Magnet
Jianjian Gong, Junsen Wang, Junsen Xiang +15
The Shastry-Sutherland lattice is a prototypical frustrated quantum magnet. It is notable for its exactly solvable dimer-singlet ground state and hosts a wealth of magnetic phenome…
Quantum Supercritical Crossover with Dynamical Singularity
Junsen Wang, Enze Lv, Xinyang Li +2
Bounded by crossover lines exhibiting universal scaling, the supercritical regime above the critical endpoint is characterized by strong fluctuations and intriguing phenomena. In t…
Quantum Simulation with Gauge Fixing: from Ising Lattice Gauge Theory to Dynamical Flux Model
Junsen Wang, Xiangxiang Sun, Wei Zheng
Quantum simulation of synthetic dynamic gauge field has attracted much attentions in recent years. There are two traditional ways to simulate gauge theories. One is to directly sim…
Magnon Damping Minimum and Logarithmic Scaling in a Kondo-Heisenberg Model
Yuan Gao, Junsen Wang, Qiaoyi Li +3
Recently, an anomalous temperature evolution of spin wave excitations has been observed in a van der Waals metallic ferromagnet FeGeTe (FGT) [S. Bao, et al., Phys. Rev. X 1…
Magnon Damping as a Probe of Kondo Coupling in Magnetically Ordered Systems
Song Bao, Junsen Wang, Shin-ichiro Yano +13
In -electron systems, there can also be intricate interplay between Kondo coupling and magnetic interactions as that in -electron systems, but the underlying mechanism remain…
Plaquette Singlet Transition, Magnetic Barocaloric Effect, and Spin Supersolidity in the Shastry-Sutherland Model
Junsen Wang, Han Li, Ning Xi +4
Inspired by recent experimental measurements [Guo \textit{et al.}, Phys. Rev. Lett.~\textbf{124}, 206602 (2020); Jiménez \textit{et al.}, Nature \textbf{592}, 370 (2021)] on frustr…
Topological Higgs Amplitude Modes in Strongly Interacting Superfluids
Junsen Wang, Youjin Deng, Wei Zheng
By studying the 2-dimensional Su-Schrieffer-Heeger-Bose-Hubbard model, we show the existence of topological Higgs amplitude modes in the strongly interacting superfluid phase. Usin…
Pseudo-time-reversal-symmetry-protected topological Bogoliubov excitations of Bose-Einstein condensates in optical lattices
Junsen Wang, Wei Zheng, Youjin Deng
Bogoliubov excitations of Bose-Einstein condensates in optical lattices may possess band topology in analogous to topological insulators in class AII of fermions. Using the languag…
