Evidence mounts quantum criticality theory
2015/3/4
A new study by a team of physicists at Rice University, Zhejiang University, Los Alamos National Laboratory, Florida State University and the Max Planck Institute adds to the growing body of evidence ...
Ginzburg-Landau-Wilson Aspects of Deconfined Criticality
Monte carlo spin vibrator parameters combined with the data
2014/12/20
Monte Carlo study of the deconfined critical action phase diagram reveals a region where spinon deconfinement occurs through a weak first-order phase transition, in agreement with Ginzburg- Landau the...
Deconfined criticality, runaway flow in the two-component scalar electrodynamics and weak first-order superfluid-solid transitions
The monte carlo model strong coupling mechanism weak coupling triple point coupling
2014/12/20
We perform a comparative Monte Carlo study of the easy-plane deconfined critical point (DCP) action and its short-range counterpart to reveal close similarities between the two models for intermediate...

Monte carlo simulation renormalization flow coupling ferromagnetic materials solid quantum
2014/12/19
Monte Carlo simulations of the SU(2)-symmetric deconfined critical point action reveal strong violations of scale invariance for the deconfinement transition. We find compelling evidence that the gene...

Symmetric Criticality Classical Field Theory
2010/12/27
This is a brief overview of work done by Ian Anderson, Mark Fels, and myself on symmetry reduction of Lagrangians and Euler-Lagrange equations, a subject closely related to Palais' Principle of Symmet...
Quantum criticality in the SO(5) bilinear-biquadratic Heisenberg chain
Quantum criticality SO(5) bilinear-biquadratic Heisenberg chain
2010/11/18
The zero-temperature properties of the SO(5) bilinear-biquadratic Heisenberg spin chain are investigated by means of a low-energy approach and large scale numerical calculations. In sharp contrast to ...
The built-up land represents an important type of overall landscape. In this paper the built-up land structure in the largest cities in the Czech Republic and selected cities in the U.S.A. is analyse...

Exact results for the criticality of quench dynamics in quantum Ising models
Exact results criticality of quench dynamics quantum Ising models
2010/4/12
Based on the obtained exact results we systematically study the quench dynamics of a one-dimensional spin-1/2 transverse field Ising model with zero- and finite-temperature initial states. We focus on...
