Quantum zero point electromagnetic energy difference between the superconducting and the normal phase in a HTc superconducting metal bulk sample
Annalisa Allocca, Saverio Avino, Sergio Balestrieri +31
We provide a novel methodological approach to the estimate of the change of the Quantum Vacuum electromagnetic energy density in a High critical Temperature superconducting metal b…
The Casimir effect in chiral media using path integral techniques
Fabrizio Canfora, David Dudal, Thomas Oosthuyse +2
We employ path integral methods to calculate the Casimir energy and force densities in a chiral extension of QED. Manifestly gauge invariant perfect electromagnetic boundary condit…
Gribov horizon in Noncommutative QED
Ozório Holanda, Marcelo S. Guimaraes, Luigi Rosa +1
It is known that Noncommutative QED (NCQED) exhibits Gribov ambiguities in the Landau gauge. These ambiguities are related to zero modes of the Faddeev-Popov operator and arise in…
The Casimir energy in terms of boundary quantum field theory: the QED case
David Dudal, Pablo Pais, Luigi Rosa
We revisit the path integral computation of the Casimir energy between two infinite parallel plates placed in a QED vacuum. We implement perfectly magnetic conductor boundary condi…
Gribov horizon, Polyakov loop and finite temperature
Fabrizio Canfora, David Dudal, Igor Justo +3
We consider finite-temperature gauge theory in the continuum formulation. Choosing the Landau gauge, the existing gauge copies are taken into account by means of the Gribov…
Extracting topological information from momentum space propagators
Fabrizio Canfora, David Dudal, Alex Giacomini +3
A new topological invariant quantity, sensitive to the analytic structure of both fermionic and bosonic propagators, is proposed. The gauge invariance of our construct is guarantee…
