Effective Field Theory on Manifolds with Boundary [PDF]

open access: yes, 2017
In the monograph Renormalization and Effective Field Theory, Costello made two major advances in rigorous quantum field theory. Firstly, he gave an inductive position space renormalization procedure for constructing an effective field theory that is ...

Advances in Quantum Theory

open access: yes, 2012
The quantum theory is the first theoretical approach that helps one to successfully understand the atomic and sub-atomic worlds which are too far from the cognition based on the common intuition or the experience of the daily-life.

Asymptotic heat kernels in quantum field theory

open access: yes, 1995
Asymptotic expansions were first introduced by Henri Poincar ́e in 1886. This paper describes their application to the semi-classical evaluation of amplitudes in quantum field theory with boundaries.

Entanglement harvesting in cosmic string spacetime

open access: yesJournal of High Energy Physics
We investigate the entanglement harvesting phenomenon for static detectors that locally interact with massless scalar fields in the cosmic string spacetime, which, though locally flat, features a conical structure defined by a deficit angle. Specifically,

Holographic Entanglement Entropy in Boundary Quantum Field Theory

open access: yes, 2018
We study the holographic entanglement entropy in a (d+1)-dimensional boundary quantum field theory at both the zero and finite temperature. The phase diagrams for the holographic entanglement entropy at various temperatures are obtained by solving the entangled surfaces in the different homology.

Boundary scattering and non-invertible symmetries in 1 + 1 dimensions

open access: yesJournal of High Energy Physics
Recent studies by Copetti, Córdova and Komatsu have revealed that when non-invertible symmetries are spontaneously broken, the conventional crossing relation of the S-matrix is modified by the effects of the corresponding topological quantum field theory

Metaphysical Underdetermination in Quantum Mechanics and Quantum Field Theory

open access: yes, 2017
The existence of ontologically different but empirically indistinguishable versions of non-relativistic quantum mechanics is one of the most serious and widely discussed cases of metaphysical underdetermination.

Complex wave functions, CPT and quantum field theory for classical generalized Ising models

open access: yesNuclear Physics B
The quantum or quantum field theory concept of a complex wave function is useful for understanding the information transport in classical statistical generalized Ising models.

Spectral geometry and quantum gravity

open access: yes, 1998
Recent progress in quantum field theory and quantum gravity relies on mixed boundary conditions involving both normal and tangential derivatives of the quantized field.
