2014/12/20
We study superfluid-solid zero-temperature transitions in two-dimensional lattice boson-spin models using worm-algorithm Monte Carlo simulations. We observe that such transitions are typically first o...
Multi-partite entanglement and quantum phase transition in the one-, two-, and three-dimensional transverse field Ising model
Multi-partite entanglement quantum phase transition transverse field Ising model
font style='font-size:12px;'>
2010/10/19
In this paper we consider the quantum phase transition in the Ising model in the presence of
a transverse field in one, two and three dimensions from a multi-partite entanglement point of
view. Usin...

By the method of terahertz photo-voltaic spectroscopy we have found a quantum phase that possesses neither continuous nor discrete translational symmetry. The phase is originated from quantum Hall sta...
Ion-trap simulation of the quantum phase transition in an exactly solvable model of spins coupled to bosons
phase transition bosons Ion-trap simulation

2010/3/10
It is known that arrays of trapped ions can be used to efficiently simulate a variety of many-body quantum systems. Here, we show how it is possible to build a model representing a spin chain interact...
Quantum entanglement in a many-body system exhibiting multiple quantum phase transitions
Quantum phase transitions Many body systems
font style='font-size:12px;'>
2010/7/5
We investigate the quantum entanglement-related features of the many-body model of Plastino and Moszkowski [N. Cimento 47 (1978) 470]. This is an exactly solvable N-body, SU2 two-level model exhibitin...
Quantum Phase Transition in a Pseudo-hermitian Dicke model
Quantum Phase Transition Pseudo-hermitian Dicke model
font style='font-size:12px;'>
2010/4/8
We show that a Dicke-type pseudo-hermitian Hamiltonian undergoes quantum phase transition by mapping it to the "Dressed Dicke Model" through a similarity transformation. We find the positive-definite ...
