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 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...

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...

2010/12/8
We describe an algorithm for distinguishing hyperbolic compo-nents in the parameter space of quadratic rational maps with a periodic critical point. We then illustrate computer images of the hyperboli...

Detecting premonitory seismicity patterns based on critical point dynamics

2009/12/9
We test the hypothesis that critical point dynamics precedes strong earthquakes in a region surrounding the future hypocenter. Therefore, we search systematically for regions obeying critical point dy...
A simple model for the earthquake cycle combining self-organized complexity with critical point behavior

2009/11/12
We have studied a hybrid model combining the forest-fire model with the site-percolation model in order to better understand the earthquake cycle. We consider a square array of sites. At each time ste...

2009/11/12
In analogy to the study of critical phase transitions in statistical physics, it has been argued recently that the fracture of heterogeneous materials could be viewed as a critical phenomenon, either ...
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...
