On the CFT operator spectrum at large global charge

- S. Hellerman, D. Orlando, S. Reffert, Masataka Watanabe
- Physics
- 6 May 2015

A bstractWe calculate the anomalous dimensions of operators with large global charge J in certain strongly coupled conformal field theories in three dimensions, such as the O(2) model and the… Expand

Electric/magnetic deformations of S3 and AdS3, and geometric cosets

- Physics
- 24 May 2004

We analyze asymmetric marginal deformations of SU(2)k and SL(2,ℝ)k WZW models. These appear in heterotic string backgrounds with non‐vanishing Neveu–Schwarz three‐forms plus electric or magnetic… Expand

Three-dimensional black holes from deformed anti de Sitter

- S. Detournay, D. Orlando, P. Petropoulos, P. Spindel
- Physics
- 28 April 2005

We present new exact three-dimensional black-string backgrounds, which contain both NS-NS and electromagnetic fields, and generalize the BTZ black holes and the black string studied by Horne and… Expand

Conformal Dimensions via Large Charge Expansion.

- D. Banerjee, S. Chandrasekharan, D. Orlando
- PhysicsPhysical review letters
- 3 July 2017

We construct an efficient Monte Carlo algorithm that overcomes the severe signal-to-noise ratio problems and helps us to accurately compute the conformal dimensions of large-Q fields at the… Expand

Generalized type IIB supergravity equations and non-Abelian classical r-matrices

- D. Orlando, S. Reffert, J. Sakamoto, Kentaroh Yoshida
- Mathematics, Physics
- 4 July 2016

We study Yang–Baxter deformations of the AdS 5 × S 5 superstring with non-Abelian classical r-matrices which satisfy the homogeneous classical Yang–Baxter equation. By performing a supercoset… Expand

Compensating strong coupling with large charge

- L. Alvarez-Gaumé, Orestis Loukas, D. Orlando, S. Reffert
- Physics
- 14 October 2016

A bstractWe study some (conformal) field theories with global symmetries in the sector where the value of the global charge Q is large. We find (as expected) that the low energy excitations of this… Expand

Large charge at large N

- 5 September 2019

Abstract
We apply the large-charge expansion to O(N) vector models starting from first principles, focusing on the Wilson-Fisher point in three dimensions. We compute conformal dimensions at zero… Expand

- Mathematics, Physics
- 18 April 2012

A bstractWe present a string theory construction of Omega-deformed four-dimensional gauge theories with generic values of ϵ1 and ϵ2. Our solution gives an explicit description of the geometry in the… Expand
