The phase space of k-Essence f(R) gravity theory
Nuclear Physics B, 2020 Among the remaining viable theories that can successfully describe the late-time era is the k-Essence theory and in this work we study in detail the phase space of k-Essence f(R) gravity in vacuum.

The geometric theory of phase transitions
Journal of Physics A: Mathematical and Theoretical, 2022 Abstract We develop a geometric theory of phase transitions (PTs) for Hamiltonian systems in the microcanonical ensemble. Such a theory allows to rephrase the Bachmann’s classification of PTs for finite-size systems in terms of geometric properties of the energy level sets (ELSs) associated to the Hamiltonian ...

Phases of chiral gauge theories [PDF]
Physical Review D, 2000 We discuss the behavior of two non-supersymmetric chiral SU(N) gauge theories, involving fermions in the symmetric and antisymmetric two-index tensor representations respectively. In addition to global anomaly matching, we employ a recently proposed inequality constraint on the number of effective low energy (massless) degrees of freedom of a theory ...

Quantum theory of reactive scattering in phase space
, 2010 We review recent results on quantum reactive scattering from a phase space perspective. The approach uses classical and quantum versions of normal form theory and the perspective of dynamical systems theory.

Phase transition in Liouville theory [PDF]
Physical Review D, 1989 We suggest that the vortices arising in a Kosterlitz-Thouless phase transition in Liouville theory correspond to transitions between different genera, producing the "plumber's nightmare" and other phases that have been predicted in fluid membrane theory from energetic considerations.

The baryonic phase in holographic descriptions of the QCD phase diagram
, 2012 We study holographic models of the QCD temperature-chemical potential phase diagram based on the D3/D7 system with chiral symmetry breaking. The baryonic phase may be included through linked D5-D7 systems. In a previous analysis of a model with a running

Continuous theory of phase separation:The Cahn-Hilliard equation [PDF]
Revista Brasileira de Ensino de FísicaIn this paper, we present a detailed deduction of the Cahn-Hilliard equation. It is a non-linear partial differential equation that continuously describes the dynamics of spinodal decomposition, i.e., spontaneous phase separation, of a binary mixture ...

Random Phase Textures: Theory and Synthesis [PDF]
IEEE Transactions on Image Processing, 2011 This paper explores the mathematical and algorithmic properties of two sample-based texture models: random phase noise (RPN) and asymptotic discrete spot noise (ADSN). These models permit to synthesize random phase textures. They arguably derive from linearized versions of two early Julesz texture discrimination theories.

Conformal field theory and the hot phase of three-dimensional U(1) gauge theory
Journal of High Energy Physics, 2019 We study the high-temperature phase of compact U(1) gauge theory in 2 + 1 dimensions, comparing the results of lattice calculations with analytical predictions from the conformal-field-theory description of the low-temperature phase of the bidimensional ...
