Critical Point of a Weakly Interacting Two-Dimensional Bose Gas
Two dimensional quantum bose gas lattice model the numerical simulation of dimensionless coefficient
2014/12/22
We study the Berezinskii-Kosterlitz-Thouless transition in a weakly interacting 2D quantum Bose gas using the concept of universality and numerical simulations of the classical |ψ|4 model on a lattice...
Weakly Interacting Bose Gas in the Vicinity of the Critical Point
Three dimensional weak bose gas the thermodynamic functions superfluid density
2014/12/20
We consider a three-dimensional weakly interacting Bose gas in the fluctuation region (and its vicinity) of the normal-superfluid phase transition point. We establish relations between basic thermodyn...
Unconventional magnetic phase diagram of cuprate superconductor La2-xSrxCuO4 at quantum critical point x = 1/9
Unconventional magnetic phase diagram cuprate superconductor La2-xSrxCuO4 quantum critical point
2012/2/27
We propose a new magnetic phase diagram of La2-xSrxCuO4 around a quantum critical point x = 1/9 based on field-cooled magnetization measurements and critical fittings. A new phase boundary Tm2(H) is d...
Probing the QCD Critical Point with Higher Moments of Net-proton Multiplicity Distributions
Net-proton Multiplicity Distributions QCD Critical Point
2011/7/21
Higher moments of event-by-event net-proton multiplicity distributions are applied to search for the QCD critical point in the heavy ion collisions. It has been demonstrated that higher moments as wel...

QCD Particle Ratio Fluctuations Multiplicity Distributions
2011/7/20
Dynamical fluctuations in global conserved quantities such as baryon number, strangeness, or charge may be observed near a QCD critical point. Results from new measurements of dynamical $K/\pi$, $p/\p...

Dynamic susceptibility of a spin-ice near the critical point
Dynamic susceptibility spin-ice near the critical point
2010/11/23
We consider spin ice magnets (primarily, Dy2Ti2O7) in the vicinity of their critical point on the (H, T )plane. We find that the longitudinal susceptibility diverges at the critical point, leading to ...
Completely mixed state is a critical point for three-qubit entanglement
Completely mixed state critical point three-qubit entanglement
2010/11/5
Pure three-qubit states have five algebraically independent and one algebraically dependent polynomial invariants under local unitary transformations and an arbitrary entanglement measure is a functi...
The concept that heavy fermions are close to a quantum critical point and that this proximity determines their physical behavior has opened new perspectives in the study of these systems. It has provi...
