Critical behavior of a nonlocal φ4 field theory and asymptotic freedom
(American Physical Society, 2018-09)
The critical behavior of a nonlocal scalar field theory is studied. This theory has a nonlocal kinetic term which involves a real power 1-2α of the Laplacian. The interaction term is the usual local φ4 interaction. The ...
Importance of asymptotic freedom for the pseudocritical temperature in magnetized quark matter
(Amer Physical Soc, 2014-08-11)
Although asymptotic freedom is an essential feature of QCD, it is absent in effective chiral quark models like the Nambu-Jona-Lasinio and linear sigma models. In this work we advocate that asymptotic freedom plays a key ...

Asymptotic stabilizability of underactuated Hamiltonian systems with two degrees of freedom
(Institute of Computer Science Izhevsk, 2019-09)
For an underactuated (simple) Hamiltonian system with two degrees of freedom and one degree of underactuation, a rather general condition that ensures its stabilizability, by means of the existence of a (simple) Lyapunov ...
3D effects of the entropic force
(Elsevier Science, 2015-02)
This work analyzes the classical statistical mechanics associated to phase-space curves in three dimensions. Special attention is paid to the entropic force. Strange effects like confinement, hard core, and asymptotic ...
Statistical mechanics of phase–space curves
(Elsevier Science, 2014-09)
We study the classical statistical mechanics of a phase–space curve. This unveils a mechanism that, via the associated entropic force, provides us with a simple realization of effects such as confinement, hard core, and ...
The role of asymptotic freedom for the pseudocritical temperature in magnetized quark matter
(Iop Publishing Ltd, 2015-01-01)
Motivated by discrepancies observed between lattice QCD simulations and quark models regarding the behavior of the pseudo critical temperature for chiral symmetry restoration as a function of the magnetic field B, we ...
