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…
