New Heat Kernel Method in Lifshitz Theories
Kevin T. Grosvenor, Charles Melby-Thompson, Ziqi Yan
We develop a new heat kernel method that is suited for a systematic study of the renormalization group flow in Horava gravity (and in Lifshitz field theories in general). This meth…
Holographic RG Flows for Kondo-like Impurities
Johanna Erdmenger, Charles Melby-Thompson, Christian Northe
Boundary, defect, and interface RG flows, as exemplified by the famous Kondo model, play a significant role in the theory of quantum fields. We study in detail the holographic dual…
p-adic CFT is a holographic tensor network
Ling-Yan Hung, Wei Li, Charles M. Melby-Thompson
The p-adic AdS/CFT correspondence relates a CFT living on the p-adic numbers to a system living on the Bruhat-Tits tree. Modifying our earlier proposal for a tensor network realiza…
Wilson line networks in -adic AdS/CFT
Ling-Yan Hung, Wei Li, Charles M. Melby-Thompson
The -adic AdS/CFT is a holographic duality based on the -adic number field . For a -adic CFT living on and with complex-valued fields, the bul…
Revisiting Lorentz violation in Horava gravity
Andrew Coates, Charles Melby-Thompson, Shinji Mukohyama
In the context of Horava gravity, the most promising known scenarios to recover Lorentz invariance at low energy are the possibilities that (1) the renormalization group flow of th…
Holographic Subregion Complexity from Kinematic Space
Raimond Abt, Johanna Erdmenger, Marius Gerbershagen +2
We consider the computation of volumes contained in a spatial slice of AdS in terms of observables in a dual CFT. Our main tool is kinematic space, defined either from the bulk…
Double Trace Interfaces
Charles Melby-Thompson, Cornelius Schmidt-Colinet
We introduce and study renormalization group interfaces between two holographic conformal theories which are related by deformation by a scalar double trace operator. At leading or…
Instantons and Entanglement Entropy
Arpan Bhattacharyya, Ling-Yan Hung, Charles M. Melby-Thompson
We would like to put the area law -- believed to by obeyed by entanglement entropies in the ground state of a local field theory -- to scrutiny in the presence of non-perturbative…
Quantization of Horava Gravity in 2+1 Dimensions
Tom Griffin, Kevin T. Grosvenor, Charles M. Melby-Thompson +1
We study quantum corrections to projectable Horava gravity with scaling in 2+1 dimensions. Using the background field method, we utilize a non-singular gauge to compute the…
Holographic Chern-Simons Defects
Mitsutoshi Fujita, Charles M. Melby-Thompson, Rene Meyer +1
We study SU(N) Yang-Mills-Chern-Simons theory in the presence of defects that shift the Chern-Simons level from a holographic point of view by embedding the system in string theory…
Dynamics of Perturbations in Double Field Theory & Non-Relativistic String Theory
Sung Moon Ko, Charles Melby-Thompson, Rene Meyer +1
Double Field Theory provides a geometric framework capable of describing string theory backgrounds that cannot be understood purely in terms of Riemannian geometry -- not only glob…
Lifshitz Gravity for Lifshitz Holography
Tom Griffin, Petr Horava, Charles M. Melby-Thompson
We argue that Horava-Lifshitz (HL) gravity provides the minimal holographic dual for Lifshitz-type field theories with anisotropic scaling and dynamical exponent z. First we show t…
Conformal Lifshitz Gravity from Holography
Tom Griffin, Petr Horava, Charles M. Melby-Thompson
We show that holographic renormalization of relativistic gravity in asymptotically Lifshitz spacetimes naturally reproduces the structure of gravity with anisotropic scaling: The h…
General Covariance in Quantum Gravity at a Lifshitz Point
Petr Horava, Charles M. Melby-Thompson
In the minimal formulation of gravity with Lifshitz-type anisotropic scaling, the gauge symmetries of the system are foliation-preserving diffeomorphisms of spacetime. Consequently…
Anisotropic Conformal Infinity
Petr Horava, Charles M. Melby-Thompson
We generalize Penrose's notion of conformal infinity of spacetime, to situations with anisotropic scaling. This is relevant not only for Lifshitz-type anisotropic gravity models, b…
