Protecting the conformal symmetry via bulk renormalization on Anti deSitter space [PDF]
, 2010 The problem of perturbative breakdown of conformal symmetry can be avoided, if a conformally covariant quantum field phi on d-dimensional Minkowski spacetime is viewed as the boundary limit of a quantum field Phi on d+1-dimensional anti-deSitter ...

Overlap singularity and time evolution in integrable quantum field theory
Journal of High Energy Physics, 2018 We study homogeneous quenches in integrable quantum field theory where the initial state contains zero-momentum particles. We demonstrate that the two-particle pair amplitude necessarily has a singularity at the two-particle threshold.

Reflection Scattering Matrix of the Ising Model in a Random Boundary Magnetic Field [PDF]
, 1997 The physical properties induced by a quenched surface magnetic field in the Ising model are investigated by means of boundary quantum field theory in replica space. Exact boundary scattering amplitudes are proposed and used to study the averaged quenched

Quantum field theories with boundaries and novel instabilities [PDF]
Physical Review D, 2014 Quantum physics on manifolds with boundary brings novel aspects due to boundary conditions. One important feature is the appearance of localised negative eigenmodes for the Laplacian on the boundary. These can potentially lead to instabilities. We consider quantum field theories on such manifolds and interpret these as leading to the onset of phase ...

Duality and transport for supersymmetric graphene from the hemisphere partition function
Journal of High Energy Physics, 2020 We use localization to compute the partition function of a four dimensional, supersymmetric, abelian gauge theory on a hemisphere coupled to charged matter on the boundary.

BOUNDARY S MATRIX AND BOUNDARY STATE IN TWO-DIMENSIONAL INTEGRABLE QUANTUM FIELD THEORY [PDF]
International Journal of Modern Physics A, 1994 We study integrals of motion and factorizable S matrices in two-dimensional integrable field theory with boundary. We propose the "boundary cross-unitarity equation," which is the boundary analog of the crossing-symmetry condition of the "bulk" S matrix.

Rényi entanglement entropies for the compactified massless boson with open boundary conditions
Journal of High Energy Physics, 2019 We investigate the Rényi entanglement entropies for the one-dimensional massless free boson compactified on a circle, which describes the low energy sector of several interacting many-body 1d systems (Luttinger Liquid).
