Entropy functionals and equilibrium states in mixed quantum-classical dynamics
Cesare Tronci, David MartÃnez-Crespo, François Gay-Balmaz
The computational challenges posed by many-particle quantum systems are often overcome by mixed quantum-classical (MQC) models in which certain degrees of freedom are treated as cl…
Heisenberg dynamics of mixed quantum-classical systems
David MartÃnez-Crespo, Cesare Tronci
We consider the dynamics of interacting quantum and classical systems in the Heisenberg representation. Unlike the usual construction in standard quantum mechanics, mixed quantum-c…
Geometric Flavours of Quantum Field Theory on a Cauchy Hypersurface: Gaussian Analysis for the Hamiltonian Formalism and Applications to Cosmology
David MartÃnez-Crespo
This thesis explores Quantum Field Theory (QFT) on curved spacetimes using a geometric Hamiltonian approach to the Schrödinger-like representation. In particular it studies the th…
An axion-like mechanism for confinement in QCD
J. L. Alonso, C. Bouthelier-Madre, J. Clemente-Gallardo +1
This letter is about confinement in QCD. At the moment we have pictures of confinement to complete our understanding of the physics of strongly interacting particles, interaction w…
