Trans-series from condensates in the non-linear sigma model
Yizhuang Liu, Marcos Mariño
In this work we provide a massless perturbative framework for the two dimensional non-linear sigma model (NLSM), that allows the computation of the perturbative series attached to…
Scalar parity-odd trispectrum from gravitational Chern-Simons interaction vertices
Giorgio Orlando, Shingo Akama, Chunshan Lin
In this paper, we explore parity violation in a scalar trispectrum from a dynamical Chern-Simons gravity theory. So far, a graviton-mediated diagram with two vertexes being of gene…
Scale without Conformal Invariance in bottom-up Holography
Lavish Chawla, Mario Flory
In holography, the isometry group of the bulk spacetime corresponds to the symmetries of the boundary theory. We thus approach the question of whether (and when) scale invariance i…
Evolution of a kink-antikink ensemble in a quantum vacuum
Mainak Mukhopadhyay, Kohta Murase, Atsushi Naruko +1
We study the flat spacetime dynamics of a classical field configuration corresponding to an ensemble of sine-Gordon kinks and antikinks, semi-classically coupled to a quantum…
Renormalon-like factorial enhancements to power expansion/OPE in a super-renormalizable 2D quartic model
Yizhuang Liu
In this work, we investigate the effects of logarithms on the asymptotic behavior of power expansion/OPE in supper-renormalizable QFTs. We performed a careful investigation of the…
