Heat kernel expansion: user's manual

DV Vassilevich - Physics reports, 2003 - Elsevier
The heat kernel expansion is a very convenient tool for studying one-loop divergences,
anomalies and various asymptotics of the effective action. The aim of this report is to collect …

Edge states at phase boundaries and their stability

M Asorey, AP Balachandran… - … in Mathematical Physics, 2016 - World Scientific
We analyze the effects of Robin-like boundary conditions on different quantum field theories
of spin 0, 1/2 and 1 on manifolds with boundaries. In particular, we show that these …

Edge states: Topological insulators, superconductors and QCD chiral bags

M Asorey, AP Balachandran… - Journal of High Energy …, 2013 - Springer
A bstract The dynamics of the magnetic field in a superconducting phase is described by an
effective massive bosonic field theory. If the superconductor is confined in a domain M with …

Hearing the boundary conditions of the one-dimensional Dirac operator

G Angelone - arXiv preprint arXiv:2311.17561, 2023 - arxiv.org
We study the isospectrality problem for a relativistic free quantum particle, described by the
Dirac Hamiltonian, confined in a one-dimensional ring with a junction. We analyze all the …

Realization of chiral symmetry in the domain model of QCD

AC Kalloniatis, SN Nedelko - Physical Review D, 2004 - APS
The domain model for the QCD vacuum has previously been developed and shown to
exhibit confinement of quarks, a strong correlation of the local chirality of quark modes, and …

Abelian Instantons and Monopole Scattering

C Csáki, R Ovadia, O Telem, J Terning… - arXiv preprint arXiv …, 2024 - arxiv.org
It is usually assumed that $4 D $ instantons can only arise in non-Abelian theories. In this
paper we re-examine this conventional wisdom by explicitly constructing instantons in an …

Chiral bag boundary conditions on the ball

G Esposito, K Kirsten - Physical Review D, 2002 - APS
Local boundary conditions for spinor fields are expressed in terms of a 1-parameter family of
boundary operators, and find applications ranging from (supersymmetric) quantum …

Stability theorems for chiral bag boundary conditions

P Gilkey, K Kirsten - Letters in mathematical physics, 2005 - Springer
We study asymptotic expansions of the smeared L 2-traces F e− t P^ 2 and FP e− tP^ 2,
where P is an operator of Dirac type and F is an auxiliary smooth endomorphism. We …

Finite-temperature properties of the Dirac operator under local boundary conditions

CG Beneventano, EM Santangelo - Journal of Physics A …, 2004 - iopscience.iop.org
We study the finite-temperature free energy and fermion number for Dirac fields in a one-
dimensional spatial segment, under two different members of the family of local boundary …
