General boundary quantum field theory: Timelike hypersurfaces in Klein-Gordon theory [PDF]
, 2005 We show that the real massive Klein-Gordon theory admits a description in terms of states on various timelike hypersurfaces and amplitudes associated to regions bounded by them. This realizes crucial elements of the general boundary framework for quantum

An Algebraic Construction of Boundary Quantum Field Theory [PDF]
Communications in Mathematical Physics, 2010 We build up local, time translation covariant Boundary Quantum Field Theory nets of von Neumann algebras A_V on the Minkowski half-plane M_+ starting with a local conformal net A of von Neumann algebras on the real line and an element V of a unitary semigroup E(A) associated with A.

Thermodynamic geometry of holographic superconductors [PDF]
Physics Letters B, 2016 We obtain the thermodynamic geometry of a (2+1) dimensional strongly coupled quantum field theory at a finite temperature in a holographic setup, through the gauge/gravity correspondence.

Finite size effects in quantum field theories with boundary from scattering data [PDF]
, 2004 We derive a relation between leading finite size corrections for a 1+1 dimensional quantum field theory on a strip and scattering data, which is very similar in spirit to the approach pioneered by Luscher for periodic boundary conditions. The consistency

Holographic Formulation of Quantum Supergravity [PDF]
Phys.Rev. D63 (2001) 064010, 2000 We show that ${\cal N}=1$ supergravity with a cosmological constant can be expressed as constrained topological field theory based on the supergroup $Osp(1|4)$.

Towards quantum field theory on spacetimes with boundaries [PDF]
The Fourteenth Marcel Grossmann Meeting, 2017 Algebraic quantization has been applied on the class of globally hyperbolic spacetime for many decades, leading to remarkable results. Nonetheless, the presence of a boundary calls for a separate treatment, since, in general, it breaks global hyperbolicity and it requires the introduction of boundary conditions to the field equation. Although a general

Boundary state in an integrable quantum field theory out of equilibrium
Physics Letters B, 2014 We study a quantum quench of the mass and the interaction in the Sinh-Gordon model starting from a large initial mass and zero initial coupling. Our focus is on the determination of the expansion of the initial state in terms of post-quench excitations. We argue that the large energy profile of the involved excitations can be relevant for the late time

An introduction to the general boundary formulation of quantum field theory [PDF]
Journal of Physics: Conference Series, 2015 We give a brief introduction to the so-called general boundary formulation (GBF) of quantum theory. This new axiomatic formulation provides a description of the quantum dynamics which is manifestly local and does not rely on a metric background structure for its definition.
