Critical behavior of supersymmetric O(N) models in the large-N limit [PDF]

, 2011
We derive a supersymmetric renormalization group (RG) equation for the scale-dependent superpotential of the supersymmetric O(N) model in three dimensions.

Existence of ground state solutions for a class of Choquard equations with local nonlinear perturbation and variable potential

Boundary Value Problems, 2021
In this paper, we focus on the existence of solutions for the Choquard equation { − Δ u + V ( x ) u = ( I α ∗ | u | α N + 1 ) | u | α N − 1 u + λ | u | p − 2 u , x ∈ R N ; u ∈ H 1 ( R N ) , $$\begin{aligned} \textstyle\begin{cases} {-}\Delta {u}+V(x)u ...

Exact renormalization group equation for the Lifshitz critical point

, 2004
An exact renormalization equation (ERGE) accounting for an anisotropic scaling is derived. The critical and tricritical Lifshitz points are then studied at leading order of the derivative expansion which is shown to involve two differential equations ...

Stationary solutions for the Cahn-Hilliard equation [PDF]

, 1998
We study the Cahn-Hilliard equation in a bounded domain without any symmetry assumptions. We assume that the mean curvature of the boundary has a nongenerate critical point.

Third order differential equations with fixed critical points [PDF]

Applied Mathematics and Computation, 2009
Fuchs determined all algebraic differential equations of first order whose solutions have no movable singularities. For the second order equation \(y''=F(z,y,y')\) this was done by Painlevé and his school. Third order equations were considered by Chazy, Garnier and Bureau.

Quantum Boltzman equation study for the Kondo breakdown quantum critical point

, 2009
We develop the quantum Boltzman equation approach for the Kondo breakdown quantum critical point, involved with two bands for conduction electrons and localized fermions. Particularly, the role of vertex corrections in transport is addressed, crucial for

The Universal Equation of State near the Critical Point of QCD

, 2004
We study the universal properties of the phase diagram of QCD near the critical point using the exact renormalization group. For two-flavour QCD and zero quark masses we derive the universal equation of state in the vicinity of the tricritical point. For

Critical points, Lauricella functions and Whitham-type equations [PDF]

Journal of Physics A: Mathematical and Theoretical, 2015
A large class of semi-Hamiltonian systems of hydrodynamic type is interpreted as the equations governing families of critical points of functions obeying the classical linear Darboux equations for conjugate nets.The distinguished role of the Euler-Poisson-Darboux equations and associated Lauricella-type functions is emphasised.

A unified description for nuclear equation of state and fragmentation in heavy ion collisions

, 1995
We propose a model that provides a unified description of nuclear equation of state and fragmentations. The equation of state is evaluated in Bragg-Williams as well as in Bethe-Peierls approximations and compared with that in the mean field theory with ...

Estimation of bulk modulus of DME on the basis of the sound speed measurement in a wide range of pressures and temperatures including the critical point

Nihon Kikai Gakkai ronbunshu, 2018
Sound speed is one of the most important thermodynamic properties for developing a fuel injection system and it is often used to validate the equation of state.
