Classical Statistical simulation of Quantum Field Theory
Takayuki Hirayama
We propose a procedure of computing the n-point function in perturbation theory of the quantum field theory as the average over the complex Gaussian noises in a classical theory. T…
Compact Star of Holographic Nuclear Matter and GW170817
Kilar Zhang, Takayuki Hirayama, Ling-Wei Luo +1
We use a holographic model of quantum chromodynamics to extract the equation of state (EoS) for the cold nuclear matter of moderate baryon density. This model is based on the Sakai…
Lorentz breaking terms from Einstein gravity
Takayuki Hirayama
We construct an action which is invariant under the foliation preserving diffeomorphism from the Einstein Hilbert action. Starting from the Einstein Hilbert action, we introduce th…
Power counting renormalizability of quantum gravity in Lifshitz spacetime
Takayuki Hirayama
We analyse the power counting renormalizability of the quantum field theory of Einstein or Einstein-Gauss-Bonnet gravity in D+2 dimensional Lifshitz spacetime. We show the spectral…
Power counting renormalizability of scalar theory in Lifshitz spacetime
Takayuki Hirayama
We analyse the power counting renormalizability of scalar theory in Lifshitz spacetime in D+2 dimensions. We show the spectral dimension becomes 2+(D/z) (z is the critical exponent…
One loop divergences in quantum gravity coupled with nonlocal matter fields
Takayuki Hirayama
We study the matter one-loop quantum corrections to the gravitational sector in a gravity theory coupled with a nonlocal scalar field. We find that non-renormalizable divergences d…
