Proposed all-versus-nothing violation of local realism in the Kitaev spin-lattice model
Ming-Guang Hu, Dong-Ling Deng, Jing-Ling Chen
We investigate the nonlocal property of the fractional statistics in Kitaev's toric code model. To this end, we construct the Greenberger-Horne-Zeilinger paradox which builds a dir…
Exact Solution of a Yang-Baxter Spin-1/2 Chain Model and Quantum Entanglement
Ming-Guang Hu, Kang Xue, Mo-Lin Ge
Entanglement is believed to be crucial in macroscopic physical systems for understanding the collective quantum phenomena such as quantum phase transitions. We start from and solve…
Geometric phase of a two-level system in a dissipative environment
Kazuo Fujikawa, Ming-Guang Hu
The geometric (Berry) phase of a two-level system in a dissipative environment is analyzed by using the second-quantized formulation, which provides a unified and gauge-invariant t…
Observation of Geometric Phases for Three-Level Systems using NMR Interferometry
Hongwei Chen, Mingguang Hu, Jingling Chen +1
Geometric phase (GP) independent of energy and time rely only on the geometry of state space. It has been argued to have potential fault tolerance and plays an important role in qu…
Maximal Quantum Violation of the CGLMP Inequality on Its Both Sides
Ming-Guang Hu, Dong-Ling Deng, Jing-Ling Chen
We investigate the maximal violations for both sides of the -dimensional CGLMP inequality by using the Bell operator method. It turns out that the maximal violations have a dece…
Gisin's theorem for two d-dimensional systems based on the Collins-Gisin-Linden-Masser-Popescu inequality
Jing-Ling Chen, Dong-Ling Deng, Ming-Guang Hu
In this Rapid Communication, we show analytically that all pure entangled states of two d-dimensional systems (qudits) violate the Collins-Gisin-Linden-Masser-Popoescu (CGLMP) ineq…
Experimental simulation of fractional statistics of abelian anyons in the Kitaev lattice-spin model
Jiang-Feng Du, Jing Zhu, Ming-Guang Hu +1
In two-dimensions, the laws of physics even permit the existence of anyons which exhibit fractional statistics ranging continuously from bosonic to fermionic behaviour. They have b…
Optical Simulation of Yang-Baxter Equation
Shuang-Wei Hu, Ming-Guang Hu, Kang Xue +1
In this paper, several proposals of optically simulating Yang-Baxter equations have been presented. Motivated by the recent development of anyon theory, we apply Temperley-Lieb alg…
SO(4) symmetry in the relativistic hydrogen atom
Jing-Ling Chen, Dong-Ling Deng, Ming-Guang Hu
We show that the relativistic hydrogen atom possesses an SO(4) symmetry by introducing a kind of pseudo-spin vector operator. The same SO(4) symmetry is still preserved in the rela…
Bell Inequality Based on Peres-Horodecki Criterion
Jing-Ling Chen, Ming-Guang Hu
We established a physically utilizable Bell inequality based on the Peres-Horodecki criterion. The new quadratic probabilistic Bell inequality naturally provides us a necessary and…
Quantum Dynamical Algebra SU(1,1) in One-Dimensional Exactly Solvable Potentials
Ming-Guang Hu, Jing-Ling Chen
We mainly explore the linear algebraic structure like SU(2) or SU(1,1) of the shift operators for some one-dimensional exactly solvable potentials in this paper. During such proces…
