Casimir Sign Reversal from Finite-Range Bogoliubov Fluctuations
Fabrizio Canfora, Pablo Pais, Luigi Rosa
We study the zero-temperature Casimir effect of a three-dimensional Bose fluid with finite-range corrections to its Bogoliubov spectrum. Beyond the universal acoustic contribution…
Non-perturbative corrections to the Casimir energy for a scalar field theory with non-linear boundary conditions
Fabrizio Canfora, David Dudal, Thomas Oosthuyse +3
We consider the case of a free real massive bulk scalar in D=4 dimensions, and embed two parallel plates as interfaces on which we impose non-linear boundary conditions, either Dir…
Fractional vorticity, Bogomol'nyi-Prasad-Sommerfield systems and complex structures for the (generalized) spinor Gross-Pitaevskii equations
Fabrizio Canfora, Pablo Pais
The (generalized) Gross-Pitaevskii equation (GPE) for a complex scalar field in two spatial dimensions is analyzed. It is shown that there is an infinite family of self-interaction…
A Bogomol'nyi-Prasad-Sommerfield bound with a first-order system in the Gross-Pitaevskii equation
Fabrizio Canfora, Pablo Pais
A novel Bogomol'nyi-Prasad-Sommerfield (BPS) bound for the Gross-Pitaevskii equations in two spatial dimensions is presented. The energy can be bounded from below in terms of the c…
A note on the Hamiltonian structure of transgression forms
Pablo Pais, Patricio Salgado-Rebolledo, Aldo Vera
By incorporating two gauge connections, transgression forms provide a generalization of Chern-Simons actions that are genuinely gauge-invariant on bounded manifolds. In this work,…
Exact mapping from the -dimensional Skyrme model to the -dimensional sine-Gordon theory and some applications
Fabrizio Canfora, Marcela Lagos, Pablo Pais +1
A remarkable exact mapping, valid for low-enough energy scales and close to a sharp boundary distribution of hadronic matter, from the -dimensional Skyrme model to the sine-…
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…
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…
On the exact quantum scale invariance of three-dimensional reduced QED theories
D. Dudal, A. J. Mizher, P. Pais
An effective quantum field theory description of graphene in the ultra-relativistic regime is given by reduced QED aka. pseudo QED aka. mixed-dimensional QED. It has been speculate…
Comments on the Chern-Simons photon term in the QED description of graphene
D. Dudal, A. J. Mizher, P. Pais
We revisit the Coleman-Hill theorem in the context of reduced planar QED. Using the global U(1) Ward identity for this non-local but still gauge invariant theory, we can confirm th…
Double non-perturbative gluon exchange: an update on the soft Pomeron contribution to pp scattering
F. E. Canfora, D. Dudal, I. F. Justo +4
We employ a set of recent, theoretically motivated, fits to non-perturbative unquenched gluon propagators to check in how far double gluon exchange can be used to describe the soft…
The Gribov problem in presence of background field for Yang-Mills theory
Fabrizio Canfora, Diego Hidalgo, Pablo Pais
The Gribov problem in the presence of a background field is analyzed: in particular, we study the Gribov copies equation in the Landau-De Witt gauge as well as the semi-classical G…
Comments on the compatibility of thermodynamic equilibrium conditions with lattice propagators
Fabrizio Canfora, Alex Giacomini, Pablo Pais +2
In this paper the compatibility is analyzed of the non-perturbative equations of state of quarks and gluons arising from the lattice with some natural requirements for self-gravita…
Gribov gap equation at finite temperature
Fabrizio Canfora, Pablo Pais, Patricio Salgado-Rebolledo
In this paper the Gribov gap equation at finite temperature is analyzed. The solutions of the gap equation (which depend explicitly on the temperature) determine the structure of t…
