Higher-order Topological Anderson Insulators
Yan-Bin Yang, Kai Li, L. -M. Duan +1
We study disorder effects in a two-dimensional system with chiral symmetry and find that disorder can induce a quadrupole topological insulating phase (a higher-order topological p…
A (Dummy's) Guide to Working with Gapped Boundaries via (Fermion) Condensation
Jiaqi Lou, Ce Shen, Chaoyi Chen +1
We study gapped boundaries characterized by "fermionic condensates" in 2+1 d topological order. Mathematically, each of these condensates can be described by a super commutative Fr…
Hinge solitons in three-dimensional second-order topological insulators
Yu-Liang Tao, Ning Dai, Yan-Bin Yang +2
A second-order topological insulator in three dimensions refers to a topological insulator with gapless states localized on the hinges, which is a generalization of a traditional t…
Chiral Induced Spin Selectivity as a Spontaneous Intertwined Order
Xiaopeng Li, Jue Nan, Xiangcheng Pan
Chiral induced spin selectivity (CISS) describes efficient spin filtering by chiral molecules. This phenomenon has led to nanoscale manipulation of quantum spins with promising app…
Topological Quantum Compiling with Reinforcement Learning
Yuan-Hang Zhang, Pei-Lin Zheng, Yi Zhang +1
Quantum compiling, a process that decomposes the quantum algorithm into a series of hardware-compatible commands or elementary gates, is of fundamental importance for quantum compu…
Precise Programmable Quantum Simulations with Optical Lattices
Xingze Qiu, Jie Zou, Xiaodong Qi +1
We present an efficient approach to precisely simulate tight binding models with optical lattices, based on programmable digital-micromirror-device (DMD) techniques. Our approach c…
