Weak First-Order Superfluid-Solid Quantum Phase Transitions
Zero the two-dimensional lattice model monte carlo simulation the Hamiltonian parameter space
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...
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...
First-order transition in Potts models with "invisible' states: Rigorous proofs
First-order transition Potts models Rigorous proofs
2011/7/28
Abstract: In some recent papers by Tamura, Tanaka and Kawashima [arXiv:1102.5475, arXiv:1012.4254], a class of Potts models with "invisible" states was introduced, for which the authors argued by nume...
Percolation in Interdependent and Interconnected Networks: Abrupt Change from Second to First Order Transition
Cascading failures, Percolation, Coupled networks, Phase transition
2011/9/5
Robustness of two coupled networks system has been studied only for dependency coupling (S. Buldyrev et. al., Nature, 2010) and only for connectivity coupling (E. A. Leicht and R. M. D’Souza, arxiv:09...

Phase Transition 8 Flavor QCD
2011/1/6
As part of our ongoing investigations of QCD with many flavors of quarks, here we report on studies of the finite temperature phase transition for eight-flavor QCD with the DBW2 gauge action and na\"i...

A simple protocol for the probability weights of the simulated tempering algorithm: applications to first-order phase transitions
simulated tempering first-order phase transitions eigenvalues of the transfer matrix Ising and lattice-gas models
2010/11/19
The simulated tempering (ST) is an important method to deal with systems whose phase spaces are hard to sample ergodically. However, it uses accepting probabilities weights which often demand involvin...

First Order Phase Transition of a Long Polymer Chain
First Order Phase Transition Long Polymer Chain
2010/11/17
We consider a model consisting of a self-avoiding polygon occupying a variable density of the sites of a square lattice. A fixed energy is associated with each 90◦-bend of the polygon. We use a ...
Effective Theory in Spinfoam Cosmology: A First Order LQG-corrected FRW Cosmology and the Stiff Fluid
Effective Theory Spinfoam Cosmology First Order LQG-corrected FRW Cosmology Stiff Fluid
2010/12/20
We present an effective theory of a basic holomorphic spinfoam cosmology peaked on homoge-
neous isotropic metrics. The quantum-corrected Hamiltonian constraint of this effective theory is motivated ...

Quantum Phase Transition Changing Problem Hamiltonians
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...
Dynamo Onset as a First-Order Transition: Lessons from a Shell Model for Magnetohydrodynamics
First-Order Transition Magnetohydrodynamics
