The Page curve of Hawking radiation from semiclassical geometry

- Ahmed Almheiri, R. Mahajan, J. Maldacena, Y. Zhao
- Physics
- 29 August 2019

We consider a gravity theory coupled to matter, where the matter has a higher-dimensional holographic dual. In such a theory, finding quantum extremal surfaces becomes equivalent to finding the… Expand

Islands outside the horizon

- Ahmed Almheiri, R. Mahajan, J. Maldacena
- Physics
- 24 October 2019

We consider an AdS$_2$ black hole in equilibrium with a bath, which we take to have a dual description as (0+1)-dimensional quantum mechanical system coupled to a (1+1)-dimensional field theory… Expand

The conformal bootstrap at finite temperature

- Luca V. Iliesiu, M. Koloğlu, R. Mahajan, Eric Perlmutter, D. Simmons-Duffin
- Physics
- 28 February 2018

A bstractWe initiate an approach to constraining conformal field theory (CFT) data at finite temperature using methods inspired by the conformal bootstrap for vacuum correlation functions. We focus… Expand

Entanglement islands in higher dimensions.

- Ahmed Almheiri, R. Mahajan, J. E. Santos
- Physics
- 21 November 2019

It has been suggested in recent work that the Page curve of Hawking radiation can be recovered using computations in semi-classical gravity provided one allows for "islands" in the gravity region of… Expand

Upper Bound on Diffusivity.

- T. Hartman, S. Hartnoll, R. Mahajan
- Physics, Medicine
- Physical review letters
- 31 May 2017

The linear growth of operators in local quantum systems leads to an effective light cone even if the system is nonrelativistic. We show that the consistency of diffusive transport with this light… Expand

Non-Fermi liquids and the Wiedemann-Franz law

- R. Mahajan, M. Barkeshli, S. Hartnoll
- Physics
- 15 April 2013

A general discussion of the ratio of thermal and electrical conductivities in non-Fermi liquid metals is given. In metals with sharp Drude peaks, the relevant physics is correctly organized around… Expand

Transport near the Ising-nematic quantum critical point of metals in two dimensions

- S. Hartnoll, R. Mahajan, M. Punk, S. Sachdev
- Physics
- 27 January 2014

We consider two-dimensional metals near a Pomeranchuk instability which breaks ${90}^{\ensuremath{\circ}}$ lattice rotation symmetry. Such metals realize strongly coupled non-Fermi liquids with… Expand

The Landau theory of phase transitions: A mechanical analog

- Rekha S. Raorane, R. Mahajan, Praveen Pathak, V. Singh
- Physics
- 2 October 2009

The Landau theory of phase transitions occupies a centerpiece position in physics. We illustrate the theory by a pedagogical example at the pre-university level. In the example a bead of mass is… Expand

Transport in Chern-Simons-matter theories

- Guy Gur-Ari, S. Hartnoll, R. Mahajan
- Physics
- 3 May 2016

A bstractThe frequency-dependent longitudinal and Hall conductivities — σxx and σxy — are dimensionless functions of ω/T in 2+1 dimensional CFTs at nonzero temperature. These functions characterize… Expand

Matrix ensembles with global symmetries and ’t Hooft anomalies from 2d gauge theory

- Daniel Kapec, R. Mahajan, Douglas Stanford
- Physics
- 27 December 2019

The Hilbert space of a quantum system with internal global symmetry G decomposes into sectors labelled by irreducible representations of G . If the system is chaotic, the energies in each sector… Expand
