A Worldsheet Description of Instant Folded Strings
Akikazu Hashimoto, Nissan Itzhaki, Uri Peleg
Time-like linear dilaton backgrounds admit a classical solution that describes a closed folded string that is created at an instant. We refer to such strings as Instant Folded Stri…
Comments on the negative specific heat of the deformed symmetric product CFT
Soumangsu Chakraborty, Akikazu Hashimoto
We show that the deformation of conformal field theories whose entropy grows as for exhibits negative specific heat in its microcanonical thermo…
Weighed average over Narain moduli space as deformation of CFT target space
Soumangsu Chakraborty, Akikazu Hashimoto
We consider the weighted average of a two dimensional CFT, whose target space is , over its Narain moduli space. We take as the weighing function the integral kernel which giv…
Entanglement Entropy for , , deformed holographic CFT
Soumangsu Chakraborty, Akikazu Hashimoto
We derive the geodesic equation for determining the Ryu-Takayanagi surface in deformed by single trace deforma…
Strings, Symmetric Products, deformations and Hecke Operators
Akikazu Hashimoto, David Kutasov
We derive a formula for the torus partition sum of the symmetric product of deformed CFT's, using previous work on long strings in (deformed) , and universality. T…
, Partition Sums From String Theory
Akikazu Hashimoto, David Kutasov
We calculate the torus partition sum of a general with left and right moving conserved currents and , perturbed by a combination of the irrelevant operators $T\…
