Low-temperature Quantum-corrected Holographic Transport with Momentum Relaxation
Suman Das, Sabyasachi Maulik, Leopoldo A. Pando Zayas +1
We determine the quantum corrections to transport arising from fluctuations of the near-AdS throat of near-extremal black branes in holographic models with momentum relaxatio…
Low-Temperature Holographic Conductivity
Sabyasachi Maulik, Leopoldo A. Pando Zayas, Jingchao Zhang
We revisit holographic electrical conductivity in the regime of very low temperatures where quantum fluctuations in the throat of the near-extremal, asymptotically AdS dual bla…
Effective dynamics and quantum information in de Sitter wedge holography
Sabyasachi Maulik, Soumen Pari
In this paper, we study codimension-two holography in a de Sitter (dS) wedge setup, based on the idea of wedge holography. We consider a -dimensional Anti-de Sitter (AdS) bulk…
Entanglement entropy and its linear response following a global quench in holographic Gauss-Bonnet gravity
Sabyasachi Maulik, Soumen Pari
Growth of entanglement entropy in time-dependent states formed due to a global quench in holographic conformal field theories which admit an Einstein-Gauss-Bonnet dual gravity desc…
Logarithmic corrections to near-extremal entropy of charged de Sitter black holes
Sabyasachi Maulik, Arpita Mitra, Debangshu Mukherjee +1
We calculate the logarithmic temperature corrections to the thermodynamic entropy of four-dimensional near-extremal Reissner-Nordström de Sitter (dS) black hole by computing a one-…
Quantum-Corrected Hawking Radiation from Near-Extremal Kerr-Newman Black Holes
Sabyasachi Maulik, Xin Meng, Leopoldo A. Pando Zayas
Near-extremal black holes have a long AdS throat in their near-horizon region. Quantum fluctuations in the throat region are effectively governed by a quantum version of Jackiw…
Universality in Logarithmic Temperature Corrections to Near-Extremal Rotating Black Hole Thermodynamics in Various Dimensions
Sabyasachi Maulik, Leopoldo A. Pando Zayas, Augniva Ray +1
The low-temperature thermodynamics of near-extremal rotating black holes has recently been revisited to incorporate one-loop contributions that are dominant in this regime. We disc…
Entanglement from holography for five-dimensional charged Schrödinger black hole
Suman Das, Sabyasachi Maulik
We study entanglement entropy in a non-relativistic Schrödinger field theory at finite temperature and electric charge using the principle of gauge/gravity duality. The spacetime g…
One-Loop Quantum Effects in Carroll Scalars
Kinjal Banerjee, Rudranil Basu, Bhagya Krishnan +3
Carrollian field theories at the classical level possess an infinite number of space-time symmetries, namely the supertranslations. In this article, we inquire whether these symmet…
Pseudo complexity of purification for free scalar field theories
Aranya Bhattacharya, Arpan Bhattacharyya, Sabyasachi Maulik
We compute the pseudo complexity of purification corresponding to the reduced transition matrices for free scalar field theories with an arbitrary dynamical exponent. We plot the b…

The spacetime is an exact solution of configuration in type IIA supergravity and can accommodate charged excitations of the fundame…
Entanglement entropy and the first law at third order for boosted black branes
Sabyasachi Maulik, Harvendra Singh
Gauge/gravity duality relates an AdS black hole with uniform boost with a boosted strongly-coupled CFT at finite temperature. We study the perturbative change in holographic entang…

Aranya Bhattacharya, Anindya Chanda, Sabyasachi Maulik +2
Recently, remarkable progress in recovering the Page curve of an evaporating black hole (BH) in Jackiw-Teitelboim gravity has been achieved through use of Quantum Extremal surfaces…
