Journal ArticleDOI
Noncommutative gravitational quantum well
TL;DR: In this article, a model where non-commutativity of both configuration and momentum spaces is considered is proposed and the problem of the two-dimensional gravitational quantum well is analyzed.
Journal ArticleDOI
Ising exponents from the functional renormalisation group
Daniel F. Litim,Dario Zappalà +1 more
TL;DR: In this article, the authors studied the 3D Ising universality class using the functional renormalization group and computed the leading index, the subleading symmetric and antisymmetric corrections to scaling, the anomalous dimension, the scaling solution, and the eigenperturbations at criticality.
Journal ArticleDOI
Constraining and applying a generic high-density equation of state
TL;DR: In this article, the authors discuss the constant speed of sound (CSS) parametrization of the equation of state of high-density matter and its application to the field correlator method (FCM) model of quark matter.
Journal ArticleDOI
Nonuniform symmetry breaking in noncommutative λ Φ 4 theory
Paolo Castorina,Dario Zappalà +1 more
TL;DR: In this paper, the Hartree-Fock approximation was used to analyze spontaneous symmetry breaking in noncommutative cutoff theory and showed that there is no phase transition to a constant vacuum expectation of the field.
Journal ArticleDOI
Improving the renormalization group approach to the quantum-mechanical double well potential
TL;DR: In this article, the gap between ground and first excited state of the quantum-mechanical double well is calculated using the renormalization group equations to the second order in the derivative expansion, obtained within a class of proper time regulators.
