Polar compactons and solitons in a two dimensional optical waveguide: Theory and simulations
Results in Optics, 2023 The propagation of optical cylindrical compactons and solitons in a two dimensional nonlocal nonlinear waveguide is deeply investigated by carrying a particular emphasis on its nonlinear response function.

A variational derivation of the velocity distribution functions for nonequilibrium, multispecies, weakly interacting, spherically symmetric many-body systems [PDF]
Journal of Statistical Physics, 1982 The most probable velocity distribution function of each component,fa, of a nonequilibrium multispecies spherically symmetric system of particles (stellar plasma atmospheres and winds, stellar systems, pellet-fusion systems) is analytically derived forthe case in which each component is described by the first six moments of fa.

Generalized Devil's staircase and RG flows
Nuclear Physics B, 2023 We discuss a two-parameter renormalization group (RG) flow when parameters are organized in a single complex variable, τ, with modular properties. Throughout the work we consider a special limit when the imaginary part of τ characterizing the disorder ...

Tail shape and the swimming speed of sharks
Royal Society Open Science, 2023 Trait-based ecology is a rapidly growing approach for developing insights and predictions for data-poor species. Caudal tail fin shape has the potential to reveal much about the energetics, activity and ecology of fishes and can be rapidly measured from ...

Parabolic Catalan numbers count flagged Schur functions and their appearances as type A Demazure characters (key polynomials) [PDF]
Discrete Mathematics & Theoretical Computer Science, 2017 Fix an integer partition lambda that has no more than n parts. Let beta be a weakly increasing n-tuple with entries from {1,..,n}. The flagged Schur function indexed by lambda and beta is a polynomial generating function in x_1, .., x_n for certain ...

On Weakly $W_3$-Symmetric Manifolds [PDF]
, 2011 summary:The object of the present paper is to study weakly $W_3$-symmetric manifolds and its decomposability with the existence of such notions. Among others it is shown that in a decomposable weakly $W_3$-symmetric manifold both the decompositions are ...

Dynamical current correlations in Cooper pair splitters based on proximized quantum dots
New Journal of Physics, 2021 Entanglement of electrons is studied by means of current–current correlations in two Cooper pair splitter devices: with one and two proximized quantum dots (1QD and 2QD), in presence of intra- and inter-dot Coulomb interactions, and weakly coupled with ...

Regularization dependence of the OTOC. Which Lyapunov spectrum is the physical one?
Journal of High Energy Physics, 2019 We study the contour dependence of the out-of-time-ordered correlation function (OTOC) both in weakly coupled field theory and in the Sachdev-Ye-Kitaev (SYK) model. We show that its value, including its Lyapunov spectrum, depends sensitively on the shape

Pseudo-Riemannian weakly symmetric manifolds of low dimension [PDF]
, 2019 summary:We give a classification of pseudo-Riemannian weakly symmetric manifolds in dimensions $2$ and $3$, based on the algebraic approach of such spaces through the notion of a pseudo-Riemannian weakly symmetric Lie algebra.

Journal of Function Spaces and Applications, 2013 We obtain some fixed point theorems for JH-operators and occasionally weakly g-biased maps on a set X together with the function F:X×X→Δ without using the triangle inequality and without using the symmetric condition.
