Critical phenomena and Kibble–Zurek scaling in the long-range quantum Ising chain [PDF]
We investigate an extension of the quantum Ising (QI) model in one spatial dimension including long-range 1 / r α interactions in its statics and dynamics with possible applications from heteronuclear polar molecules in optical lattices to trapped ions ...

Critical phenomena in complex networks [PDF]
The combination of the compactness of networks, featuring small diameters, and their complex architectures results in a variety of critical effects dramatically different from those in cooperative systems on lattices.

Critical phenomena are reported for SbSI. In particular it is observed that critical Rayleigh scattering (critical opalescence) occurs near the phase transition.

Critical phenomena for systems under constraint
It is well known that the imposition of a constraint can transform the properties of critical systems. Early work on this phemomenon by Essam and Garelick, Fisher, and others, focused on the effects of constraints on the leading critical exponents ...

Critical phenomena in ferromagnetic antidot lattices
In this paper a quantitative theoretical formulation of the critical behavior of soft mode frequencies as a function of an applied magnetic field in two-dimensional Permalloy square antidot lattices in the nanometric range is given according to ...

Carnot Cycles in a Harmonically Confined Ultracold Gas across Bose–Einstein Condensation
Carnot cycles of samples of harmonically confined ultracold 87Rb fluids, near and across Bose–Einstein condensation (BEC), are analyzed. This is achieved through the experimental determination of the corresponding equation of state in terms of the ...

Investigation of Ring and Star Polymers in Confined Geometries: Theory and Simulations
The calculations of the dimensionless layer monomer density profiles for a dilute solution of phantom ideal ring polymer chains and star polymers with f=4 arms in a Θ-solvent confined in a slit geometry of two parallel walls with repulsive surfaces and ...

The Theory of Boundary Critical Phenomena [PDF]
An introduction into the theory of boundary critical phenomena and the application of the field-theoretical renormalization group method to these is given. The emphasis is on a discussion of surface critical behavior at bulk critical points of magnets, binary alloys, and fluids. Yet a multitude of related phenomena are mentioned.

Fenômenos críticos: 150 anos desde Cagniard de la Tour
Em 1822 o cientista francês Caignard de la Tour descobriu os fenômenos críticos. Com o intuito de comemorar os 150 anos do aniversário de sua morte, revisamos neste artigo o contexto e a história inicial de sua descoberta.
