Exact Solutions for Pairing Interactions [PDF]

open access: yes, 2013
The exact solution of the BCS pairing Hamiltonian was found by Richardson in 1963. While little attention was paid to this exactly solvable model in the remainder of the 20th century, there was a burst of work at the beginning of this century focusing on its applications in different areas of quantum physics.

Asymptotic behaviour of solutions to nonlinear parabolic equations with variable viscosity and geometric terms

open access: yesElectronic Journal of Differential Equations, 2007
In this paper we study the asymptotic behaviour of solutions of certain nonlinear parabolic equations with variable viscosity and geometric terms. We generalize the results on the large time behaviour and vanishing viscosity limits obtained earlier ...

Exact solutions for the biadjoint scalar field

open access: yesPhysics Letters B, 2016
Biadjoint scalar theories are novel field theories that arise in the study of non-abelian gauge and gravity amplitudes. In this short paper, we present exact nonperturbative solutions of the field equations, and compare their properties with monopole ...

Exact Solutions in Poincaré Gauge Gravity Theory

open access: yesUniverse, 2019
In the framework of the gauge theory based on the Poincaré symmetry group, the gravitational field is described in terms of the coframe and the local Lorentz connection. Considered as gauge field potentials, they give rise to the corresponding field

Exact solutions of 2d supersymmetric gauge theories

open access: yesJournal of High Energy Physics, 2019
We study dynamics of two-dimensional non-abelian gauge theories with N $$ \mathcal{N} $$ = (0, 2) supersymmetry that include N $$ \mathcal{N} $$ = (0, 2) supersymmetric QCD and its generaliza- tions.

ABOUT EXACT SOLUTIONS OF MEASUREMENT'S INVERSE PROBLEMS

open access: yesVìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Modelûvannâ, 2013
The inverse problems of measurement are investigated in this paper. The mainhypothesis was suggested for estimation from below of exact solutions of suchproblems. Two practical inverse problems have been considered as examples: inverse problem of Krylov,

Supersymmetric Ito equation: Bosonization and exact solutions

open access: yesAIP Advances, 2013
Based on the bosonization approach, the N=1 supersymmetric Ito (sIto) system is changed to a system of coupled bosonic equations. The approach can effectively avoid difficulties caused by intractable fermionic fields which are anticommuting.
