Chemical-potential-assisted particle production in FRW spacetimes
نویسندگان
چکیده
A bstract We analyze gravitational particle production assisted by chemical potential. By utilizing the uniformly smoothed Stokes-line method and Borel summation, we gain insight into fine-grained history of enhanced production. Analytic/semi-analytic formulae describing amount, time width are obtained for both spin-1 spin-1/2 particles in various FRW spacetimes. Our work also serves as a concrete demonstration applied to cosmology.

Particle Production of Coherently Oscillating Nonclassical Inflaton in Frw Universe
We study particle production of coherently oscillating inflaton in the semiclassical theory of gravity by representing inflaton in coherent and squeezed state formalisms. A comparative study of the inflaton in classical gravity with coherent state inflaton in semiclassical gravity is also presented. email: [email protected] ∗Corresponding address : P.K.Suresh, School of Physics,University of...
متن کاملGreen's functions for gravitational waves in FRW spacetimes.
A method for calculating the retarded Green's function for the gravitational wave equation in Friedmann-Roberson-Walker spacetimes, within the formalism of linearized Einstein gravity is developed. Hadamard's general solution to Cauchy's problem for second-order, linear partial differential equations is applied to the FRW gravitational wave equation. The retarded Green's function may be calcula...
متن کاملParticle production from marginally trapped surfaces of general spacetimes
We provide a general formalism that allows to analyze the phenomenon of tunneling in arbitrary spacetimes. We show that a flux of particles produced by tunneling through general marginally trapped surfaces may be perceived by some privileged observers. We discuss how this particle perception can be related to Hawking/Unruh radiation in specific cases. Our approach naturally leads to an expressi...
متن کاملUltrasound-Assisted Biodiesel Production in microreactors
The ultrasound-assisted (UA) soybean oil methanolysis using KOH as a catalyst was studied at different reaction conditions in a microreactor. Box–Behnken experimental design, with three variables, was performed and the effects of three reaction variables i.e. reaction temperature, catalyst concentration and the methanol-to-oil molar ratio on fatty acid methyl ester (FAME) yield were evaluated b...
متن کاملThe CWKB Method of Particle Production in Periodic Potential
In this work we study the particle production in time dependent periodic potential using the method of complex time WKB (CWKB) approximation. In the inflationary cosmology at the end of inflationary stage, the potential becomes time dependent as well as periodic. Reheating occurs due to particle production by the oscillating inflaton field. Using CWKB we obtain almost identical results on catas...
