Target space entanglement in Matrix Models
Harsha R. Hampapura, Jonathan Harper, Albion Lawrence
We study target space entanglement in gauged multi-matrix models as models of entanglement between groups of D-branes separated by a planar entangling surface, paying close attenti…
On phase transitions in the Rényi entropies of 2+1-d large-N interacting vector models
Harsha R. Hampapura, Albion Lawrence, Stefan Stanojevic
We consider the reduced density matrix for a disc in the ground state of the interacting fixed points of the large-N O(N) vector model in 2+1 dimensions. Using the map to the free…
Scrambling in Two-Dimensional Conformal Field Theories with Light and Smeared Operators
Harsha R. Hampapura, Andrew Rolph, Bogdan Stoica
We study quantum chaos in two dimensional conformal field theories, building on the work analyzing the out-of-time order thermal correlation functions using large-c Virasoro blocks…
Two-dimensional RCFT's without Kac-Moody symmetry
Harsha R. Hampapura, Sunil Mukhi
Using the method of modular-invariant differential equations, we classify a family of Rational Conformal Field Theories with two and three characters having no Kac-Moody algebra. I…
Cosets of Meromorphic CFTs and Modular Differential Equations
Matthias R. Gaberdiel, Harsha R. Hampapura, Sunil Mukhi
Some relations between families of two-character CFTs are explained using a slightly generalised coset construction, and the underlying theories (whose existence was only conjectur…
On 2d Conformal Field Theories with Two Characters
Harsha R. Hampapura, Sunil Mukhi
Rational CFT's are classified by an integer , the number of zeroes of the Wronskian of their characters in moduli space. For they satisfy non-singular modular-invari…
