У оквиру семинара Центра за изучавање комплексних система Института за физику у Београду, у четвртак, 23. марта 2023. године у 14 часова путем Zoom платформе, др Петар Тадић (Департман за физику, Јејл Универзитет, САД), одржаће предавање:
Conformal bootstrap of the five-point correlators
САЖЕТАК:
In this talk we will review the five-point correlation function of external scalar operators in the conformal field theory. We will show how one can compute the five-point conformal blocks for arbitrary spin of exchanged operators in any spacetime dimension using only two quadratic Casimir differential equations and the appropriate ansatz of the conformal blocks. We will then consider the five-point correlators in the free theory and the critical Ising model in three-dimensional spacetime. We will truncate the operator product expansions (OPE) in the correlators to include just a finite number of exchanged operators and use the crossing symmetry to numerically compute the OPE coefficients of two spinning and one scalar operator. These OPE coefficients were not previously known in the critical Ising model.
