Quench dynamics of topological quantum phase transition in Wen-plaquette model
Long Zhang, Su-Peng Kou, Youjin Deng
We study the quench dynamics of the topological quantum phase transition in the two-dimensional transverse Wen-plaquette model, which has a phase transition from a Z2 topologically…
Worm Monte Carlo study of the honeycomb-lattice loop model
Qingquan Liu, Youjin Deng, Timothy M. Garoni
We present a Markov-chain Monte Carlo algorithm of "worm"type that correctly simulates the O(n) loop model on any (finite and connected) bipartite cubic graph, for any real n>0, an…
Berezinskii-Kosterlitz-Thouless-like percolation transitions in the two-dimensional XY model
Hao Hu, Youjin Deng, Henk W. J. Blöte
We study a percolation problem on a substrate formed by two-dimensional XY spin configurations, using Monte Carlo methods. For a given spin configuration we construct percolation c…
Worm-type Monte Carlo simulation of the Ashkin-Teller model on the triangular lattice
Jian-Ping Lv, Youjin Deng, Qing-Hu Chen
We investigate the symmetric Ashkin-Teller (AT) model on the triangular lattice in the antiferromagnetic two-spin coupling region (). In the limit, we…
Interference of overlap-free entangled photons with a Mach-Zehnder-like interferometer
Xian-Min Jin, Cheng-Zhi Peng, Tao Yang +1
Using spontaneous parametric down conversion and a 50:50 beam splitter, we generate coaxial polarization-entangled photon pairs, of which the two photons are far separated from eac…
Quantum interface between frequency-uncorrelated down-converted entanglement and atomic-ensemble quantum memory
Xian-Min Jin, Jian Yang, Han Zhang +15
Photonic entanglement source and quantum memory are two basic building blocks of linear-optical quantum computation and long-distance quantum communication. In the past decades, in…
