Classical Observables from Causal Response Functions
Shovon Biswas, Julio Parra-Martinez
We revisit the calculation of classical observables from causal response functions, following up on recent work by Caron-Huot at al. [JHEP 01 (2024) 139]. We derive a formula to co…
Massless Fermions on a half-space: The curious case of 2+1-dimensions
Shovon Biswas, Gordon W. Semenoff
Boundary conditions for a massless Dirac fermion in 2+1 dimensions where the space is a half-plane are discussed in detail. It is argued that linear boundary conditions that leave…
Holographic BCFT Spectra from Brane Mergers
Shovon Biswas, Jani Kastikainen, Sanjit Shashi +1
We use holography to study the spectra of boundary conformal field theories (BCFTs). To do so, we consider a 2-dimensional Euclidean BCFT with two circular boundaries that correspo…
Soft Scalars don't decouple
Shovon Biswas, Gordon W. Semenoff
It is demonstrated that it is possible to find a field theory containing massless scalar particles which has infrared structure closely resembling that of quantum electrodynamics a…
The Spectrum of Boundary States in Symmetric Orbifolds
Alexandre Belin, Shovon Biswas, James Sully
We give an explicit construction of the complete set of Cardy boundary states that respect the extended chiral algebra for symmetric product orbifolds. The states are labelled by a…
Bohr-van Leeuwen theorem in non-commutative space
Shovon Biswas
Bohr-van Leeuwen theorem has been studied in non-commutative space where the space coordinates do not commute. It has been found that in non-commutative space Bohr-van Leeuwen theo…
Repulsive Casimir force in Bose-Einstein Condensate
Mir Mehedi Faruk, Shovon Biswas
We study the Casimir effect for a three dimensional system of ideal free massive Bose gas in a slab geometry with Zaremba and anti-periodic boundary conditions. It is found that fo…
Quantum gravity effects in statistical mechanics with modified dispersion relation
Shovon Biswas, Mir Mehedi Faruk
Planck scale inspired theories which are also often accompanied with maximum energy and/or momentum scale predict deformed dispersion relations compared to ordinary special relativ…
