The infrared behaviour of quantum field theories confined in bounded domains is strongly
dependent on the shape and structure of space boundaries. The most significant physical …

We formulate a self-consistent model of the integer quantum Hall effect on an infinite strip,
using boundary conditions to investigate the influence of finite-size effects on the Hall …

Following the seminal works of Asorey–Ibort–Marmo and Muñoz–Castañeda–Asorey about
selfadjoint extensions and quantum fields in bounded domains, we compute all the heat …

The path is explored between one-dimensional scattering through Dirac-δ walls and one-
dimensional quantum field theories defined on a finite length interval with Dirichlet boundary …

The theory of self-adjoint extensions of first-and second-order elliptic differential operators
on manifolds with boundary is studied via its most representative instances: Dirac and …

The dynamics of quantum field theories on bounded domains requires the introduction of
boundary conditions on the quantum fields. We address the problem from a very general …

The effect of boundary conditions on the vacuum structure of quantum field theories is
analysed from a quantum information viewpoint. In particular, we analyse the role of …

The dynamics of classical field theories is usually governed by field equations, but when
fields are constrained to bounded domains it is also dependent on its boundary conditions …

We investigate the self-adjoint extensions of the Dirac operator of a massive one-
dimensional field of mass m confined in a finite filament of length L. We compute the …

The possibility of treating boundary conditions in terms of a bilocal dynamical field is
formalized in terms of a boundary action. This allows for a simple path-integral perturbation …
