-symmetric Field Theories at Finite Temperature
Oleksandr Diatlyk, Andrei Katsevich, Fedor K. Popov
We investigate the thermal properties of -symmetric scalar field theories with purely imaginary couplings. The free energy governs the asymptotic density of states, p…
Defect Fusion and Casimir Energy in Higher Dimensions
Oleksandr Diatlyk, Himanshu Khanchandani, Fedor K. Popov +1
We study the operator algebra of extended conformal defects in more than two spacetime dimensions. Such algebra structure encodes the combined effect of multiple impurities on phys…
Holography on the Quantum Disk
Ahmed Almheiri, Fedor K. Popov
Motivated by recent study of DSSYK and the non-commutative nature of its bulk dual, we review and analyze an example of a non-commutative spacetime known as the quantum disk propos…
Factorizing Defects from Generalized Pinning Fields
Fedor K. Popov, Yifan Wang
We introduce generalized pinning fields in conformal field theory that model a large class of critical impurities at large distance, enriching the familiar universality classes. We…
Effective Field Theory of Conformal Boundaries
Oleksandr Diatlyk, Himanshu Khanchandani, Fedor K. Popov +1
We introduce an effective field theory (EFT) for conformal impurity by considering a pair of transversely displaced impurities and integrating out modes with mass inversely proport…
Beyond in Large Conformal Vector Models at Finite Temperature
Oleksandr Diatlyk, Fedor K. Popov, Yifan Wang
We investigate finite-temperature observables in three-dimensional large critical vector models taking into account the effects suppressed by . Such subleading contri…
