Title Black holes in omega-deformed gauged N=8 supergravity Type
Year 2014 Publication Physics Letters B Abbreviated Journal Phys. Lett. B
Volume 732 Issue Pages 137-141
Keywords
Abstract Motivated by the recently found 4-dimensional omega-deformed gauged supergravity, we investigate the black hole solutions within the single scalar field consistent truncations of this theory. We construct black hole solutions that have spherical, toroidal, and hyperbolic horizon topologies. The scalar field is regular everywhere outside the curvature singularity and the stress-energy tensor satisfies the null energy condition. When the parameter CO does not vanish, there is a degeneracy in the spectrum of black hole solutions for boundary conditions that preserve the asymptotic Anti-de Sitter symmetries. These boundary conditions correspond to multi-trace deformations in the dual field theory. (C) 2014 The Authors. Published by Elsevier B.V.

Title On attractor mechanism of AdS(4) black holes Type
Year 2013 Publication Physics Letters B Abbreviated Journal Phys. Lett. B
Volume 727 Issue 4-5 Pages 568-572
Keywords
Abstract We construct a general family of exact non-extremal 4-dimensional black holes in AdS gravity with U(1) gauge fields non-minimally coupled to a dilaton and a non-trivial dilaton potential. These black holes can have spherical, toroidal, and hyperbolic horizon topologies. We use the entropy function formalism to obtain the near horizon data in the extremal limit. Due to the non-trivial self-interaction of the scalar field, the zero temperature black holes can have a finite horizon area even if only the electric field is turned on. (C) 2013 Elsevier B.V.

Title Hairy AdS solitons Type
Year 2016 Publication Physics Letters B Abbreviated Journal Phys. Lett. B
Volume 762 Issue Pages 80-85
Keywords
Abstract We construct exact hairy AdS soliton solutions in Einstein-dilaton gravity theory. We examine their thermodynamic properties and discuss the role of these solutions for the existence of first order phase transitions for hairy black holes. The negative energy density associated to hairy AdS solitons can be interpreted as the Casimir energy that is generated in the dual filed theory when the fermions are antiperiodic on the compact coordinate.

Title On the thermodynamics of hairy black holes Type
Year 2015 Publication Physics Letters B Abbreviated Journal Phys. Lett. B
Volume 743 Issue Pages 154-159
Keywords
Abstract We investigate the thermodynamics of a general class of exact 4-dimensional asymptotically Anti-de Sitter hairy black hole solutions and show that, for a fixed temperature, there are small and large hairy black holes similar to the Schwarzschild-AdS black hole. The large black holes have positive specific heat and so they can be in equilibrium with a thermal bath of radiation at the Hawking temperature. The relevant thermodynamic quantities are computed by using the Hamiltonian formalism and counterterm method. We explicitly show that there are first order phase transitions similar to the Hawking-Page phase transition. (C) 2015 The Authors. Published by Elsevier B.V.

Title Holographic equation of state in fluid/gravity duality Type
Year 2017 Publication Physics Letters B Abbreviated Journal Phys. Lett. B
Volume 770 Issue Pages 272-277
Keywords
Abstract We establish a precise relation between mixed boundary conditions for scalar fields in asymptotically anti de Sitter spacetimes and the equation of state of the dual fluid. We provide a detailed derivation of the relation in the case of five bulk-dimensions for scalar fields saturating the Breitenlohner-Freedman bound. As a concrete example, we discuss the five dimensional scalar-tensor theories describing dark energy in four dimensions. (C) 2017 Published by Elsevier B.V.

Title Rotating D0-branes and consistent truncations of supergravity Type
Year 2013 Publication Physics Letters B Abbreviated Journal Phys. Lett. B
Volume 727 Issue 4-5 Pages 516-523
Keywords
Abstract The fluctuations around the D0-brane near-horizon geometry are described by two-dimensional S0(9) gauged maximal supergravity. We work out the U(1)(4) truncation of this theory whose scalar sector consists of five dilaton and four axion fields. We construct the full non-linear Kaluza-Klein ansatz for the embedding of the dilaton sector into type IIA supergravity. This yields a consistent truncation around a geometry which is the warped product of a two-dimensional domain wall and the sphere S-8. As an application, we consider the solutions corresponding to rotating D0-branes which in the near-horizon limit approach AdS(2) x M-8 geometries, and discuss their thermodynamical properties. More generally, we study the appearance of such solutions in the presence of non-vanishing axion fields. (C) 2013 Elsevier B.V. All rights reserved.

Title The b ghost of the pure spinor formalism is nilpotent Type
Year 2011 Publication Physics Letters B Abbreviated Journal Phys. Lett. B
Volume 695 Issue 1-4 Pages 312-316
Keywords b ghost; Ghost; Nilpotent; Spinor formalism
Abstract The ghost for world-sheet reparametrization invariance is not a fundamental field in the pure spinor formalism. It is written as a combination of pure spinor variables which have conformal dimension two and such that it commutes with the BRST operator to give the world-sheet stress tensor. We show that the ghost variable defined in this way is nilpotent since the OPE of b with itself does not have singularities. (C) 2010 Elsevier B.V. All rights reserved.

Title New family of Maxwell like algebras Type
Year 2016 Publication Physics Letters B Abbreviated Journal Phys. Lett. B
Volume 759 Issue Pages 507-512
Keywords
Abstract We introduce an alternative way of closing Maxwell like algebras. We show, through a suitable change of basis, that resulting algebras are given by the direct sums of the AdS and the Maxwell algebras already known in the literature. Casting the result into the S-expansion method framework ensures the straightaway construction of the gravity theories based on a found enlargement. (C) 2016 The Authors. Published by Elsevier B.V.

Title Two-mode squeezed state generation using the Bohm potential Type
Year 2022 Publication Modern Physics Letters B Abbreviated Journal Mod. Phys. Lett. B
Volume 36 Issue 09 Pages 2250025
Keywords Time-dependent coupled harmonic oscillator; Bohm potential; entangled states; two-mode squeezed states
Abstract We show that two-mode squeezed vacuum-like states may be engineered in the Bohm-Madelung formalism by adequately choosing the phase of the wave function. The difference between our wave function and the one of the squeezed vacuum states is given precisely by the phase we selected. We would like to stress that the engineering of two-mode vacuum states is possible due to the existence of the Bohm potential, and it is relevant because of its potential use in the propagation of optical fields, where it may render a variety of applications in optics. The approach to generate non-classical states, namely, two-mode squeezed states of a quantum mechanical system is one of the first applications of the Madelung-Bohm formalism.

Title Non-Hermitian dynamics from Hermitian systems: Do-it-yourself Type
Year 2024 Publication Modern Physics Letters B Abbreviated Journal Mod. Phys. Lett. B
Volume Early Access Issue Pages
Keywords PT symmetric Hamiltonians; non-unitary transformations; Wick rotation
Abstract We show that several Hamiltonians that are PT symmetric may be taken to Hermitian Hamiltonians via a non-unitary transformation and vice versa. Therefore, a recipe to produce tractable non-Hermitian Hamiltonians is given (a set of instructions to do it yourself). We also show that for some specific Hamiltonians such non-unitary transformations may be associated, via a fractional-Wick rotation, to complex time.
