Algebraic Gorkov solution in finite systems for the separable pairing interaction
(Elsevier Science, 2020-02)
An algebraic Quantum Field Theory formulation of separable pairing interaction for spherical finite systems is presented. The Lipkin formulation of the model Hamiltonian and model wave function is used. The Green function ...
Examples of finite-dimensional pointed Hopf algebras in characteristic 2
(Cambridge University Press, 2020-12-01)
We present new examples of finite-dimensional Nichols algebras over fields of characteristic 2 from braided vector spaces that are not of diagonal type, admit realizations as Yetter-Drinfeld modules over finite abelian ...
Theory of polymer brushes grafted to finite surfaces
(John Wiley & Sons Inc, 2018-04)
In this work, a model based in strong-stretching theory for polymer brushes grafted to finite planar surfaces is developed and solved numerically for two geometries: stripe-like and disk-like surfaces. There is a single ...
Thermodynamics of conformal fields in topologically non-trivial space-time backgrounds
(Springer, 2013-04)
We analyze the finite temperature behaviour of massless conformally coupled scalar fields in homogeneous lens spaces S3/ℤp. High and low temperature expansions are explicitly computed and the behavior of thermodynamic ...
Aspects of quantum information in finite density field theory
(Springer, 2021-03)
We study different aspects of quantum field theory at finite density using methods from quantum information theory. For simplicity we focus on massive Dirac fermions with nonzero chemical potential, and work in 1 + 1 ...
Rényi entropy and subsystem distances in finite size and thermal states in critical XY chains
(IOP Publishing, 2020-08)
We study the R´enyi entropy and subsystem distances on one interval for the finite size and thermal states in the critical XY chains, focusing on the critical Ising chain and XX chain with zero transverse field. We construct ...
Explicit estimates for polynomial systems defining irreducible smooth complete intersections
(Polish Academy of Sciences. Institute of Mathematics, 2019-03-08)
This paper deals with properties of the algebraic variety defined as the set of zeros of a “typical” sequence of polynomials. We consider various types of “nice” varieties: set-theoretic and ideal-theoretic complete ...
Equivalence between varieties of square root rings and Boolean algebras with a distinguished automorphism
(Academic Press Inc Elsevier Science, 2006-05)
In this paper we study the variety R2 of square root rings, that is, commutative rings with unit, of characteristic two, with the square root as an additional operation. We prove that this variety is generated by the finite ...
Resolution of Algebraic Systems of Equations in the Variety of Cyclic Post Algebras
(Springer, 2011-07)
There is a constructive method to define a structure of simple k-cyclic Post algebra of order p, Lp,k, on a given finite field F(pk), and conversely. There exists an interpretation Φ1 of the variety V(Lp,k) generated by ...
