Topological crossovers near a quantum critical point [PDF]

open access: yes, 2011
We study the temperature evolution of the single-particle spectrum $\epsilon(p)$ and quasiparticle momentum distribution $n(p)$ of homogeneous strongly correlated Fermi systems beyond a point where the necessary condition for stability of the Landau ...

The phase transition of the first order in the critical region of the gas-liquid system

open access: yesCondensed Matter Physics, 2014
This is a summarising investigation of the events of the phase transition of the first order that occur in the critical region below the liquid-gas critical point.

Critical-Point Analysis For Three-Variable Cancer Angiogenesis Models

open access: yesMathematical Biosciences and Engineering, 2005
We perform critical-point analysis for three-variable systems thatrepresent essential processes of the growth of the angiogenic tumor, namely,tumor growth, vascularization, and generation of angiogenic factor (protein) asa function of effective vessel ...

Dynamic critical phenomena at a holographic critical point

open access: yes, 2011
We study time-dependent perturbations to a family of five-dimensional black hole spacetimes constructed as a holographic model of the QCD phase diagram.

Fractional Calculus Extension of the Kinetic Theory of Fluids: Molecular Models of Transport within and between Phases

open access: yesMathematics, 2022
The application of fractional calculus in the field of kinetic theory begins with questions raised by Bernoulli, Clausius, and Maxwell about the motion of molecules in gases and liquids.

Existence results for a sublinear second order Dirichlet boundary value problem on the half-line [PDF]

open access: yesOpuscula Mathematica, 2020
In this paper we study the existence of nontrivial solutions for a boundary value problem on the half-line, where the nonlinear term is sublinear, by using Ekeland's variational principle and critical point theory.

On the existence of three solutions for quasilinear elliptic problem [PDF]

open access: yesOpuscula Mathematica, 2012
We consider a quasilinear elliptic problem of the type \(-\Delta_p u = \lambda (f(u)+\mu g(u))\) in \(\Omega\), \(u|_{\partial \Omega} =0\), where \(\Omega \in \mathbb{R}^N\) is an open and bounded set, \(f\), \(g\) are continuous real functions on ...

Davies Critical Point and Tunneling

open access: yes, 2012
From the point of view of tunneling, the physical meaning of the Davies critical point of a second order phase transition in the black hole thermodynamics is clarified.

QCD Critical Point: The Race is On [PDF]

open access: yes, 2014
A critical point in the phase diagram of Quantum Chromodynamics (QCD), if established either theoretically or experimentally, would be as profound a discovery as the good-old gas-liquid critical point.

Critical-point wedge filling and critical-point wetting

open access: yesPhysical Review E
For simple fluids adsorbed at a planar solid substrate (modeled as an inert wall) it is known that critical-point wetting, that is, the vanishing of the contact angle θ at a temperature T_{w} lying below that of the critical point T_{c}, need not occur. While critical-point wetting necessarily happens when the wall-fluid and fluid-fluid forces have the
