WebOct 26, 2024 · The main purpose of the workshop is to discuss the recent progress in the field of quantum integrable lattice models, integrable quantum field theories and exactly solvable models of statistical … WebAug 11, 2024 · We propose an integrable bootstrap framework for the computation of correlation functions for superstrings in AdS 3 × S 3 × T 4 backgrounds supported by an arbitrary mixture or Ramond-Ramond and Neveu-Schwarz-Neveu-Schwarz fluxes. The framework extends the “hexagon tessellation” approach which was originally proposed …

Dirac delta function and correlation functions

WebWe represent the density matrix of a finite segment of the integrable isotropic spin-1 chain in the thermodynamic limit as a multiple integral. Our integral formula is valid at finite … WebIt is defined as the integral of the product of the two functions after one is reflected about the y-axis and shifted. The choice of which function is reflected and shifted before the integral does not change the integral result (see commutativity ). The integral is evaluated for all values of shift, producing the convolution function. hello yli

Integrability in String, Field, and Condensed Matter Theory

A correlation function is a function that gives the statistical correlation between random variables, contingent on the spatial or temporal distance between those variables. If one considers the correlation function between random variables representing the same quantity measured at two different points, then this is often referred to as an autocorrelation function, which is made up of autocorrel… WebThe correlation functions of integrable quantum model have been largely studied over the last decades [1,2]. The prominent case is the XXZ spin-1/2 chain, which was successfully studied in the thermodynamic limit by many different viewpoints, ranging from multiple inte- WebSep 30, 2016 · Should we just give a meaning to this type of correlation functions (involving a Delta) only when they are inside an integral? (and if it's the case, then assume we want to integrate this correlation from t ′ = 0 to t ′ = t, then upon using different sequences of functions (to produce Delta), the final result of the integration may be … hello ytl
