Wave-functional formulation of dissipative CSL models
Y. M. P. Gomes
We formulate minimal and dissipative Continuous Spontaneous Localization (CSL) dynamics in the functional Schrödinger representation for a non-relativistic bosonic field. In this f…
Dissipative stabilization of Ostrogradsky modes in non-equilibrium field theory

Everlyn Martins, Y. M. P. Gomes, Marcus Benghi Pinto +1
It is known that the Fierz identities predict that the Gross-Neveu and Thirring models should be equivalent when describing systems composed of a single fermionic flavor, . He…

We analyze the chiral symmetry breaking in a planar four-fermion model with non-null chemical potential, temperature and including the effect of the tilt of the Dirac cone. The sys…
