Field-Selected Topological Buffering in a Disordered Skyrmion Crystal
Wenyu Su, Nvsen Ma, Chen Cheng +1
Quenched disorder can disrupt crystalline order without immediately destroying the topology of its constituent textures, but the relation between these processes in skyrmion crysta…
Scaling of Disorder Operator and Entanglement Entropy at Easy-Plane Deconfined Quantum Criticalities
Jiarui Zhao, Zi Yang Meng, Yan-Cheng Wang +1
We systematically investigate the scaling behaviors of the disorder operator and the entanglement entropy (EE) of the easy-plane JQ (EPJQ) model at its transitions between the anti…
Zigzag magnetic order in a novel tellurate compound NaNiTeO with = 1 chains
Cheng Su, Xu-Tao Zeng, Yi Li +9
NaNiTeO is a rare example in the transition-metal tellurate family of realizing an = 1 spin-chain structure. By performing neutron powder diffraction measurements…
Quantum Monte Carlo study of honeycomb antiferromagnets under a triaxial strain
Junsong Sun, Nvsen Ma, Tao Ying +2
The honeycomb antiferromagnet under a triaxial strain is studied using the quantum Monte Carlo simulation. The strain dimerizes the exchange couplings near the corners, thus destru…
Scaling of disorder operator at deconfined quantum criticality
Yan-Cheng Wang, Nvsen Ma, Meng Cheng +1
We study scaling behavior of the disorder parameter, defined as the expectation value of a symmetry transformation applied to a finite region, at the deconfined quantum critical po…
Topological phase transition and single/multi anyon dynamics of spin liquid
Zheng Yan, Yan-Cheng Wang, Nvsen Ma +2
Among the quantum many-body models that host anyon excitation and topological orders, quantum dimer models (QDM) provide a unique playground for studying the relation between singl…

We report heat capacity measurements of SrCu(BO) under high pressure along with simulations of relevant quantum spin models and map out the phase diagram of the…
Criticality and scaling corrections for two-dimensional Heisenberg models in plaquette patterns with strong and weak couplings
Xiaoxue Ran, Nvsen Ma, Dao-Xin Yao
We use the stochastic series expansion quantum Monte Carlo method to study the Heisenberg models on the square lattice with strong and weak couplings in the form of three different…
Emmy Noether looks at the deconfined quantum critical point
Nvsen Ma, Yi-Zhuang You, Zi Yang Meng
Noether's theorem is one of the fundamental laws of physics, relating continuous symmetries and conserved currents. Here we explore the role of Noether's theorem at the deconfined…
Anomalous quantum-critical scaling corrections in two-dimensional antiferromagnets
Nvsen Ma, Phillip Weinberg, Hui Shao +3
We study the Néel-paramagnetic quantum phase transition in two-dimensional dimerized Heisenberg antiferromagnets using finite-size scaling of quantum Monte Carlo data. We r…
Dynamical Signature of Fractionalization at the Deconfined Quantum Critical Point
Nvsen Ma, Guang-Yu Sun, Yi-Zhuang You +4
Deconfined quantum critical points govern continuous quantum phase transitions at which fractionalized (deconfined) degrees of freedom emerge. Here we study dynamical signatures of…
