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…
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…
