An integrable deformation of the sine(sinh)-Gordon model -- Non-Lie algebra
Meseret Asrat
In this paper we present an integrable model in two dimensions. It is a deformation of the sine(sinh)-Gordon model. We give its Lax connection. We also obtain its (classical) -m…
Thermal/Black hole phase transition and entanglement entropy in (2 + 1)D
Meseret Asrat
We consider a one parameter family of holographic solutions in classical string theory in three spacetime dimensions. In Euclidean space, the solutions interpolate smoothly without…
Kalb-Ramond field, black holes and black strings in (2 + 1)D
Meseret Asrat
New rotating dilaton black hole and black string solutions in three spacetime dimensions are obtained. The background spacetime interpolates between Anti-de Sitter and a (an asympt…
Rotating strings and anomalous dimensions in Non-AdS holography
Meseret Asrat
In this paper we consider certain rigidly rotating closed string configurations in an asymptotically non-AdS string background. The string background is a deformation of $AdS_3 \ti…
Moving holographic boundaries
Meseret Asrat
In this paper, we show that for one sign of the deformation coupling single-trace deformation moves the holographic screen in Gödel universe radially inward. For the ot…
Comments on 1+1d QCD with heavy adjoint quarks
Meseret Asrat
In this paper, we determine at weak coupling the non-relativistic -body Schrödinger equation that describes the low-lying color singlet bound states of two dimensional adjoint $…
, the entanglement wedge cross section, and the breakdown of the split property
Meseret Asrat, Jonah Kudler-Flam
We consider fine-grained probes of the entanglement structure of two dimensional conformal field theories deformed by the irrelevant double-trace operator and its closel…
KdV Charges and the Generalized Torus Partition Sum in deformation
Meseret Asrat
We consider KdV currents in a quantum field theory obtained by deforming a two dimensional conformal field theory on a cylinder via the irrelevant operator . In this pap…
Entropic c-functions in deformations
Meseret Asrat
We study the holographic entanglement entropy of an interval in a quantum field theory obtained by deforming a holographic two-dimensional conformal field theory via a general line…
Comments on asymptotic safety in four-dimensional supersymmetric gauge theories
Meseret Asrat
We discuss asymptotic safety in four-dimensional supersymmetric gauge theories. Our main conclusion is that in a reasonable definition of this phenomenon there ar…
Holography Beyond AdS
Meseret Asrat, Amit Giveon, Nissan Itzhaki +1
We continue our study of string theory in a background that interpolates between in the infrared and a linear dilaton spacetime in the UV. This backgrou…
