Avoid First Order Quantum Phase Transition by Changing Problem Hamiltonians
Quantum Phase Transition Changing Problem Hamiltonians
font style='font-size:12px;'>
2010/10/29
The problem Hamiltonian of the adiabatic quantum algorithm for the maximum-weight independent set problem (MIS) that is based on the reduction to the Ising problem has flexible parameters. We show tha...
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...
Ion-trap simulation of the quantum phase transition in an exactly solvable model of spins coupled to bosons
phase transition bosons Ion-trap simulation

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...
Decoherence due to an excited state quantum phase transition in a two-level boson model
Decoherence excited state quantum phase transition two-level boson model
font style='font-size:12px;'>
2010/3/10
The decoherence induced on a single qubit by its interaction with the environment is studied. The environment is modelled as a scalar two-level boson system that can go through either first order or c...
Decoherence as a signature of an excited state quantum phase transition
Decoherence excited state quantum phase transition
font style='font-size:12px;'>
2010/3/10
We analyze the decoherence induced on a single qubit by the interaction with a two-level boson system with critical internal dynamics. We explore how the decoherence process is affected by the presenc...
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 ...
