Exact null octagon

open access: yesJournal of High Energy Physics, 2020
We consider the so-called simplest correlation function of four infinitely heavy half-BPS operators in planar N $$ \mathcal{N} $$ = 4 SYM in the limit when the operators are light-like separated in a sequential manner.

From Multiple Integrals to Fredholm Determinants [PDF]

open access: yesProgress of Theoretical Physics Supplement, 2008
We consider a multiple integral representation for the finite temperature density-density correlation functions of the one-dimensional Bose gas with delta function interaction in the limits of infinite and vanishing repulsion. In the former case a known Fredholm determinant is recovered.

Asymptotics of Fredholm Determinant Associated with the Pearcey Kernel [PDF]

open access: yesCommunications in Mathematical Physics, 2021
The Pearcey kernel is a classical and universal kernel arising from random matrix theory, which describes the local statistics of eigenvalues when the limiting mean eigenvalue density exhibits a cusp-like singularity. It appears in a variety of statistical physics models beyond matrix models as well.

The Malgrange Form and Fredholm Determinants [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2017
We consider the factorization problem of matrix symbols relative to a closed contour, i.e., a Riemann-Hilbert problem, where the symbol depends analytically on parameters. We show how to define a function $τ$ which is locally analytic on the space of deformations and that is expressed as a Fredholm determinant of an operator of "integrable" type in the

Zero temperature momentum distribution of an impurity in a polaron state of one-dimensional Fermi and Tonks-Girardeau gases

open access: yesSciPost Physics, 2020
We investigate the momentum distribution function of a single distinguishable impurity particle which formed a polaron state in a gas of either free fermions or Tonks-Girardeau bosons in one spatial dimension.

Numerical Solution for Arbitrary Domain of Fractional Integro-differential Equation via the General Shifted Genocchi Polynomials

open access: yesJournal of Function Spaces, 2023
The Genocchi polynomial has been increasingly used as a convenient tool to solve some fractional calculus problems, due to their nice properties. However, like some other members in the Appell polynomials, the nice properties are always limited to the ...

A Fredholm determinant formula for Toeplitz determinants [PDF]

open access: yesIntegral Equations and Operator Theory, 2000
We prove a formula expressing a general n by n Toeplitz determinant as a Fredholm determinant of an operator 1-K acting on l_2({n,n+1,...}), where the kernel K admits an integral representation in terms of the symbol of the original Toeplitz matrix.

Non-perturbative approaches to the quantum Seiberg-Witten curve

open access: yesJournal of High Energy Physics, 2020
We study various non-perturbative approaches to the quantization of the Seiberg-Witten curve of N $$ \mathcal{N} $$ = 2, SU(2) super Yang-Mills theory, which is closely related to the modified Mathieu operator.

Semiclassical approach to form factors in the sinh-Gordon model

open access: yesJournal of High Energy Physics, 2023
Form factors in the sinh-Gordon model are studied semiclassically for small values of the parameter b ~ ħ 1/2 in the background of a radial classical solution, which describes a heavy exponential operator placed at the origin.
