Effective gravitational action for 2D massive fermions
نویسندگان
چکیده
We work out the effective gravitational action for 2D massive Euclidean fermions in a small mass expansion. Besides leading Liouville action, order $m^2$ contains piece characteristic of Mabuchi much as scalars, but also several non-local terms involving Green's functions and at coinciding points on manifold.

Bosonic effective action for interacting fermions
We present a bosonic description for systems of interacting fermions. A systematic expansion of the free energy starts with a solution to the lowest order Schwinger-Dyson or gap equation. Part of the phase diagram for the Hubbard model is computed in this framework. We propose a two particle irreducible formulation of an exact renormalization group equation for computations beyond leading order...
متن کاملVacuum States in 2D Tachyon Effective Action
In this paper we will study ground states of the toy model of 2D closed string tachyon effective action. We will firstly construct the classical solutions of the tachyon effective action that do not induce backreaction on metric and dilaton. Then we will study the quantum mechanics of the zero mode of the tachyon field. We will find family of vacuum states that are labeled with single parameter...
متن کاملEffective action and decoherence by fermions in quantum cosmology
We develop the formalism for the one-loop no-boundary state in a cosmological model with fermions. We use it to calculate the reduced density matrix for an inflaton field by tracing out the fermionic degrees of freedom, yielding both the fermionic effective action and the standard decoherence factor. We show that dimensional regularisation of ultraviolet divergences would lead to an inconsisten...
متن کاملOn gravitational interaction of fermions
We discuss some aspects of the gravitational interaction of the relativistic quantum particles with spin 1/2. The exact Foldy-Wouthuysen transformation is constructed for the Dirac particle coupled to the static spacetime metric. The quasirelativistic limit of the theory is then analyzed. Using the analogous method, we obtain the exact Cini-Touschek transformation and discuss the ultra-relativi...
متن کاملNeutrino Masses from Non-minimal Gravitational Interactions of Massive Neutral Fermions
A new mechanism is proposed for generating neutrino masses radiatively through a non-minimal coupling to gravity of fermionic bilinears involving massive neutral fermions. Such coupling terms can arise in theories where the gravity sector is augmented by a scalar field. They necessarily violate the principle of equivalence, but such violations are not ruled out by present experiments. It is sho...
