Strings from interacting quantum fields
Domingo Gallegos, Umut Gursoy, Natale Zinnato
We generalize Gopakumar's microscopic derivation of Witten diagrams in large N free quantum field theory [1] to interacting theories in perturbative expansion. For simplicity we co…
From Feynman graphs to Witten diagrams
Domingo Gallegos, Umut Gürsoy, Natale Zinnato
We investigate the possibility of generalizing Gopakumar's microscopic derivation [1] of Witten diagrams in large N free quantum field theory to interacting theories. For simplicit…
Analytic long-lived modes in charged critical plasma
Umut Gursoy, Matti Järvinen, Giuseppe Policastro +1
Fluctuations around critical behavior of a holographic charged plasmas are investigated by studying quasi-normal modes of the corresponding black branes in 5D Einstein-Maxwell-Dila…
A non-relativistic limit of M-theory and 11-dimensional membrane Newton-Cartan geometry
Chris D. A. Blair, Domingo Gallegos, Natale Zinnato
We consider a non-relativistic limit of the bosonic sector of eleven-dimensional supergravity, leading to a theory based on a covariant `membrane Newton-Cartan' (MNC) geometry. The…
Non-Riemannian gravity actions from double field theory
A. D. Gallegos, U. Gürsoy, S. Verma +1
Non-Riemannian gravitational theories suggest alternative avenues to understand properties of quantum gravity and provide a concrete setting to study condensed matter systems with…
Torsional Newton Cartan gravity from non-relativistic strings
A. D. Gallegos, U. Gursoy, N. Zinnato
We study propagation of closed bosonic strings in torsional Newton-Cartan geometry based on a recently proposed Polyakov type action derived by dimensional reduction of the ordinar…
More on microstate geometries of 4d black holes
Massimo Bianchi, Jose Francisco Morales, Lorenzo Pieri +1
We construct explicit examples of microstate geometries of four-dimensional black holes that lift to smooth horizon-free geometries in five dimensions. Solutions consist of half-BP…
