Purdue researchers phase transition thought impossible
2015/11/12
An ultrapure material taken to pressures greater than that in the depths of the ocean and chilled to temperatures colder than outer space has revealed an unexpected phase transition that crosses two d...
The Dynamic Phase Transition for Decoding Algorithms
Error correction coding the random structure random graph random arrangement
2015/8/21
The state-of-the-art error correcting codes are based on large random constructions (random graphs, random permutations, . . . ) and are decoded by linear-time iterative algorithms. Because of these f...
Phase Transition Induced Vertical Alignment of Ultrathin Gallium Phosphide Nanowire Arrays on Silicon by Chemical Beam Epitaxy
Vertical Alignment Ultrathin Gallium Phosphide Nanowire Arrays Silicon Chemical Beam Epitaxy
2016/12/2
CBE and CVD were performed in an ultra-high vacuum (UHV) system. The background pressure was kept at 1 × 10-10 mbar. The Au was deposited by MBE on a hydrogen terminated Si substrate with a surface te...
Subsonic phase transition waves in bistable lattice models with small spinodal region
phase transitions in lattices heteroclinic travelling waves FPU-type chains kinetic relations
2012/6/14
Phase transitions waves in atomic chains with double-well potential play a fundamental role in materials science, but very little is known about their mathematical properties. In particular, the only ...
Phase transition in crowd synchrony of delay-coupled multilayer laser networks
Phase transition crowd synchrony delay-coupled multilayer laser networks Chaotic Dynamics
2012/4/26
An analogy between crowd synchrony and multi-layer neural network architectures is proposed. It indicates that many non-identical dynamical elements (oscillators) communicating indirectly via a few me...
Ising model: secondary phase transition
Ising model secondary phase transition General Physics
2012/4/20
Lttice-spin phonons are considered, which make the heat capacity at the critical temperature satisfy experimental observations better. There is a BEC phase transition in an Ising model attributable to...
Infinite-Period Phase Transition versus Nucleation in a Stochastic Model of Collective Oscillations
Infinite-Period Phase Transition Collective Oscillations
2011/9/2
A lattice model of three-state stochastic phase-coupled oscillators has been shown by Wood et al. [Phys. Rev. Lett. 96, 145701 (2006)] to exhibit a phase transition at a critical value of the coupling...
On critical scaling at the QCD N_f=2 chiral phase transition
chiral phase transition critical scaling at the QCD N_f=2
2011/7/21
We investigate the critical scaling of the quark propagator of N_f=2 QCD close to the chiral phase transition at finite temperature. We argue that it is mandatory to take into account the back-reactio...
Experimental equation of state in proton-proton and proton-antiproton collisions and phase transition to quark gluon plasma
quark gluon plasma average transverse momentum vs pseudorapidity density
2011/7/21
We deduce approximate equations of state from experimental measurements in proton-proton and proton-antiproton collisions.
Magnetic Fields at First Order Phase Transition: A Threat to Electroweak Baryogenesis
Magnetic Fields First Order Phase Transition:Electroweak Baryogenesis
2011/10/17
The generation of the observed baryon asymmetry may have taken place during the electroweak phase transition, thus involving physics testable at LHC, a scenario dubbed electroweak baryogenesis. In thi...
Nuclear matter and chiral phase transition at large-$N_{c}$
Institute of theoretical Physics, Johann Wolfgang Goethe University
2011/7/21
Two aspects of the QCD phase diagrams are studied in the limit of a large number of colors: at zero temperature and nonzero density the (non)existence of nuclear matter, and at zero density and nonzer...
A one-dimensional coagulation-fragmentation process with a dynamical phase transition
one-dimensional coagulation-fragmentation process dynamical phase transition Probability
2011/9/13
Abstract: We introduce a reversible Markovian coagulation-fragmentation process on the set of partitions of $\{1,...,L\}$ into disjoint intervals. Each interval can either split or merge with one of i...
The Phase Transition for Dyadic Tilings
dyadic rectangle tiling phase transition percolation generating function
2011/9/5
Abstract: A dyadic tile of order n is any rectangle obtained from the unit square by n successive bisections by horizontal or vertical cuts. Let each dyadic tile of order n be available with probabili...
