Unusual slow energy relaxation induced by mobile discrete breathers in one-dimensional lattices with next-nearest-neighbor coupling
Bin Xu, Jun Zhang, Wei Zhong +2
We study the energy relaxation process in one-dimensional (1D) lattices with next-nearest-neighbor (NNN) couplings. This relaxation is produced by adding damping (absorbing conditi…
Modification of the hybridization gap by twisted stacking of quintuple layers in a three dimensional topological insulator thin film
Changyuan Zhou, Dezhi Song, Yeping Jiang +1
Twisting the stacking of layered materials leads to rich new physics. A three dimensional (3D) topological insulator film host two dimensional gapless Dirac electrons on top and bo…
Visualizing the in-gap states in domain boundaries of ultra-thin topological insulator films
Jun Zhang, Junbo Cheng, Shuaihua Ji +1
Ultra-thin topological insulators provide a platform of realizing many exotic phenomena such a Quantum spin Hall effect, Quantum anomalous Hall effect, etc. These effects or states…
Chirp effects on pair production in oscillating electric fields with spatial inhomogeneity
Mamutjan Ababekri, Sayipjamal Dulat, B. S. Xie +1
Dirac-Heisenberg-Wigner formalism is used to study chirp effects on the vacuum pair creation under inhomogeneous electric fields. For rapidly oscillating electric fields, the parti…
Effects of finite spatial extent on Schwinger pair production
Mamutjan Ababekri, Bai-Song Xie, Jun Zhang
Electron-positron pair production from vacuum in external electric fields with space and time dependencies is studied numerically using real time Dirac-Heisenberg-Wigner formalism.…
Spin-glass ground state in a triangular-lattice compound YbZnGaO
Zhen Ma, Jinghui Wang, Zhao-Yang Dong +19
We report on comprehensive results identifying the ground state of a triangular-lattice structured YbZnGaO to be spin glass, including no long-range magnetic order, prominent b…
