Holographic information theoretic quantities for Lifshitz black hole
Sourav Karar, Sunandan Gangopadhyay
In this paper, we have investigated the holographic entanglement entropy for a linear subsystem in a -dimensional Lifshitz black hole. The entanglement entropy has been analys…
Holographic subregion complexity of boosted black brane and Fisher information
Sourav Karar, Rohit Mishra, Sunandan Gangopadhyay
In this paper, we have studied the holographic subregion complexity for boosted black brane for strip like subsystem. The holographic subregion complexity has been computed for a s…
Anharmonicity can enhance the performance of quantum refrigerators
Sourav Karar, Shounak Datta, Sibasish Ghosh +1
We explore a thermodynamical effect of anharmonicity in quantum mechanical oscillators. We show that small quartic perturbations to the oscillator potential lead to an enhancement…
Holographic entanglement thermodynamics for higher dimensional charged black hole
Sourav Karar, Debabrata Ghorai, Sunandan Gangopadhyay
In this paper, we have investigated the entanglement thermodynamics for -dimensional charged black hole by studying the holographic entanglement entropy in different cases…
Bulk geometry from entanglement entropy of CFT
Ashis Saha, Sourav Karar, Sunandan Gangopadhyay
In this paper, we compute the exact form of the bulk geometry emerging from a -dimensional conformal field theory using the holographic principle. We first consider the $(2+…
Holographic complexity of black non-susy D3-brane and the high temperature limit
Sourav Karar, Sunandan Gangopadhyay, A. S. Majumdar
The holographic complexity of a `black' non-susy -brane is computed. The difference in the holographic complexity between this geometry in the Fefferman-Graham coordinates and…
Holographic complexity for Lifshitz system
Sourav Karar, Sunandan Gangopadhyay
The holographic complexity of a 3+1-dimensional Lifshitz spacetime having a scaling symmetry is computed. The change in the holographic complexity between the excited state and the…
Entanglement thermodynamics for an excited state of Lifshitz system
Somdeb Chakraborty, Parijat Dey, Sourav Karar +1
A class of (2+1)-dimensional quantum many body system characterized by an anisotropic scaling symmetry (Lifshitz symmetry) near their quantum critical point can be described by a (…
