Renormalization of the cyclic Wilson loop
Matthias Berwein, Nora Brambilla, Jacopo Ghiglieri +1
In finite-temperature field theory, the cyclic Wilson loop is defined as a rectangular Wilson loop spanning the whole compactified time direction. In a generic non-abelian gauge th…
Charged black holes in nonlinear massive gravity
Yi-Fu Cai, Damien A. Easson, Caixia Gao +1
We find static charged black hole solutions in nonlinear massive gravity. In the parameter space of two gravitational potential parameters we show that below the Compton w…
A UV complete model of Large N Thermal QCD
Fang Chen, Long Chen, Keshav Dasgupta +2
Many recent works on large N holographic QCD in the planar limit have not considered UV completions, restricting exclusively towards analyzing the IR physics. Due to this, the UV p…
Emergent Universe Scenario via Quintom Matter
Yi-Fu Cai, Mingzhe Li, Xinmin Zhang
The emergent universe scenario provides a possible alternative to bouncing cosmology to avoid the Big Bang singularity problem. In this paper we study the realization of the emerge…
IR Divergence in Inflationary Tensor Perturbations from Fermion Loops
Kaixi Feng, Yi-Fu Cai, Yun-Song Piao
We estimate fermion loop corrections to the two-point correlation function of primordial tensor perturbations in a slow-roll inflationary background. We particularly compute an exp…
Towards a Nonsingular Bouncing Cosmology
Yi-Fu Cai, Damien A. Easson, Robert Brandenberger
We present a nonsingular bouncing cosmology using single scalar field matter with non-trivial potential and non-standard kinetic term. The potential sources a dynamical attractor s…
