Hamilton-Jacobi formalism for string gas thermodynamics
Anosh Joseph, S. G. Rajeev
We show that the thermodynamics of a system of strings at high energy densities under the ideal gas approximation has a formulation in terms of Hamilton-Jacobi theory. The two para…
Where does Cosmological Perturbation Theory Break Down?
Cristian Armendariz-Picon, Michele Fontanini, Riccardo Penco +1
We apply the effective field theory approach to the coupled metric-inflaton system, in order to investigate the impact of higher dimension operators on the spectrum of scalar and t…
Twisted Poincare Invariance, Noncommutative Gauge Theories and UV-IR Mixing
A. P. Balachandran, A. Pinzul, A. R. Queiroz
In the absence of gauge fields, quantum field theories on the Groenewold-Moyal (GM) plane are invariant under a twisted action of the Poincare group if they are formulated followin…
Black hole thermodynamics from simulations of lattice Yang-Mills theory
Simon Catterall, Toby Wiseman
We report on lattice simulations of 16 supercharge SU(N) Yang-Mills quantum mechanics in the 't Hooft limit. Maldacena duality conjectures that in this limit the theory is dual to…
Quantum Fields on the Groenewold-Moyal Plane
Earnest Akofor, A. P. Balachandran, Anosh Joseph
We give an introductory review of quantum physics on the noncommutative spacetime called the Groenewold-Moyal plane. Basic ideas like star products, twisted statistics, second quan…
