The long wavelength limit of hard thermal loop effective actions
F T Brandt, J Frenkel, J C Taylor
We derive a closed form expression for the long wavelength limit of the effective action for hard thermal loops in an external gravitational field. It is a function of the metric,…
Thermal instability in a gravity-like scalar theory
F. T. Brandt, Ashok Das, J. Frenkel
We study the question of stability of the ground state of a scalar theory which is a generalization of the phi^3 theory and has some similarity to gravity with a cosmological const…
Scalar-graviton interaction in the noncommutative space
F. T. Brandt, M. R. Elias-Filho
We obtain the leading order interaction between the graviton and the neutral scalar boson in the context of noncommutative field theory. Our approach makes use of the Ward identity…
Forward scattering amplitudes and the thermal operator representation
Fernando T. Brandt, Ashok Das, Josif Frenkel +1
We develop systematically to all orders the forward scattering description for retarded amplitudes in field theories at zero temperature. Subsequently, through the application of t…
