High order analysis of the limit cycle of the van der Pol oscillator
Paolo Amore, John P. Boyd, Francisco M. Fernández
We have applied the Lindstedt-Poincaré method to study the limit cycle of the van der Pol oscillator, obtaining the numerical coefficients of the series for the period and for the…
Mermin-Wagner at the Crossover Temperature
Christoph P. Hofmann
Mermin-Wagner excludes spontaneous (staggered) magnetization in isotropic ferromagnetic (antiferromagnetic) Heisenberg models at finite temperature in spatial dimensions .…
Collapse of the wavefunction, the information paradox and backreaction
Sujoy K. Modak, Daniel Sudarsky
We consider the black hole information problem within the context of collapse theories in a scheme that allows the incorporation of the backreaction to the Hawking radiation. We ex…
CP4 miracle: shaping Yukawa sector with CP symmetry of order four
P. M. Ferreira, Igor P. Ivanov, Enrique Jiménez +2
We explore the phenomenology of a unique three-Higgs-doublet model based on the single CP symmetry of order 4 (CP4) without any accidental symmetries. The CP4 symmetry is imposed o…
Quark Condensate in a Weak Magnetic Field
Christoph P. Hofmann
The low-temperature representation for the quark condensate in a weak magnetic field is known up to two-loop order. Remarkably, at one-loop order, the published series for the…
The harmonic oscillator in a space with a screw dislocation
Paolo Amore, Francisco M. Fernández
We obtain the eigenvalues of the harmonic oscillator in a space with a screw dislocation. By means of a suitable nonorthogonal basis set with variational parameters we obtain suffi…
