Holography at finite cutoff with a T2 deformationJournal of High Energy Physics - Tập 2019 - Trang 1-29 - 2019
Thomas Hartman, Jorrit Kruthoff, Edgar Shaghoulian, Amirhossein Tajdini
We generalize the $$ T\overline{T} $$ deformation of CFT2 to higher-dimensional
large-N CFTs, and show that in holographic theories, the resulting effective
field theory matches semiclassical gravity in AdS with a finite radial cutoff.
We also derive the deformation dual to arbitrary bulk matter theories.
Generally, the deformations involve background fields as well as CFT operators.

Bifundamental superfluids from holographyJournal of High Energy Physics - Tập 2015 - Trang 1-33 - 2015
Daniel Areán, Javier Tarrío
We study the holographic dual of a (2 + 1)-dimensional s-wave superfluid that
breaks an abelian U(1) × U(1) global symmetry group to the diagonal U(1) V . The
model is inspired by Sen’s tachyonic action, and the operator that condenses
transforms in the bifundamental representation of the symmetry group. We focus
on two configurations: the first one describes a marginal operator, and the
phase dia... hiện toàn bộ
High-temperature expansion of supersymmetric partition functionsJournal of High Energy Physics - Tập 2015 - Trang 1-28 - 2015
Arash Arabi Ardehali, James T. Liu, Phillip Szepietowski
Di Pietro and Komargodski have recently demonstrated a four-dimensional
counterpart of Cardy’s formula, which gives the leading high-temperature (β → 0)
behavior of supersymmetric partition functions ZSUSY(β). Focusing on
superconformal theories, we elaborate on the subleading contributions to their
formula when applied to free chiral and U(1) vector multiplets. In particular,
we see that the high... hiện toàn bộ
Holographic thermal correlators for hyperbolic CFTsJournal of High Energy Physics -
Atanu Bhatta, Shankhadeep Chakrabortty, Taniya Mandal, Arpit Maurya
Abstract We use holography to compute the exact form of retarded Green’s
functions for a scalar operator with conformal dimension ∆ in a thermal CFT and
in its related counterpart with chemical potential in R1 × H3. In our analysis,
we recast the wave equation of a scalar field in the normal form of Heun’s
equation in the dual gravity theories described by the AdS hyperbolic blackhole
and its char... hiện toàn bộ
Holographic superconductivity in the large D expansionJournal of High Energy Physics - Tập 2014 - Trang 1-22 - 2014
Roberto Emparan, Kentaro Tanabe
We study holographic superconductivity by expanding the equations in the inverse
of the number of spacetime dimensions D. We obtain an analytic expression for
the critical temperature as a function of the conformal dimension of the
condensate operator. Its accuracy for 3+1-dimensional superconductors is better
than 15%. The analysis reveals a simple, and quantitative, explanation for the
onset of ... hiện toàn bộ
Top tagging: an analytical perspectiveJournal of High Energy Physics - Tập 2018 Số 9 - 2018
Mrinal Dasgupta, Marco Guzzi, J. H. Rawling, Grégory Soyez
Abstract In this paper we study aspects of top tagging from first principles of
QCD. We find that the method known as the CMS top tagger becomes collinear
unsafe at high p t and propose variants thereof which are IRC safe, and hence
suitable for analytical studies, while giving a comparable performance to the
CMS tagger. We also develop new techniques to identify three-pronged jet
substructure, ba... hiện toàn bộ

Removing tadpoles in a soliton sectorJournal of High Energy Physics - Tập 2021 - Trang 1-18 - 2021
Jarah Evslin, Hengyuan Guo
It has long been known that perturbative calculations can be performed in a
soliton sector of a quantum field theory by using a soliton Hamiltonian, which
is constructed from the defining Hamiltonian by shifting the field by the
classical soliton solution. It is also known that even if tadpoles are
eliminated in the vacuum sector, they remain in the soliton sector. In this note
we show, in the cas... hiện toàn bộ
Complement to thermodynamics of dyonic Taub-NUT-AdS spacetimeJournal of High Energy Physics - Tập 2021 - Trang 1-28 - 2021
Robert B. Mann, Leopoldo A. Pando Zayas, Miok Park
We examine the thermodynamics of Euclidean dyonic Taub-Nut/Bolt-AdS4 black holes
for a variety of horizon geometries to understand how gauge field regularity
conditions influence the thermodynamic relations. We find several distinct
features that distinguish the NUT-charged case from its dyonic
Reissner-Nordstrom counterpart. For the Nut solution, the gauge field vanishes
at the horizon and so reg... hiện toàn bộ
