On odd number of fermion zero modes on solitons in quantum field theory and string/M theory

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yotaro Sato, Yuji Tachikawa, Taizan Watari, , | Summary: We argue that having an odd number of Majorana fermion zero modes on a dynamical point-like soliton signifies an inconsistency in a theory with 3+1 and higher dimensions. We check this statement in a couple of examples in […]

Large deviation principle for stochastic heat equation with general rough noise

Kavli Affiliate: Ran Wang | First 5 Authors: Ruinan Li, Ran Wang, Beibei Zhang, , | Summary: We study Freidlin-Wentzell’s large deviation principle for one dimensional nonlinear stochastic heat equation driven by a Gaussian noise: $$frac{partial u^varepsilon(t,x)}{partial t} = frac{partial^2 u^varepsilon(t,x)}{partial x^2}+sqrt{varepsilon} sigma(t, x, u^varepsilon(t,x))dot{W}(t,x),quad t> 0,, xinmathbb{R},$$ where $dot W$ is white in time […]

Removing the fat from your posterior samples with margarine

Kavli Affiliate: George Efstathiou | First 5 Authors: Harry T. J. Bevins, William J. Handley, Pablo Lemos, Peter H. Sims, Eloy de Lera Acedo | Summary: Bayesian workflows often require the introduction of nuisance parameters, yet for core science modelling one needs access to a marginal posterior density. In this work we use masked autoregressive […]

Gravity as a gapless phase and biform symmetries

Kavli Affiliate: Austin Joyce | First 5 Authors: Kurt Hinterbichler, Diego M. Hofman, Austin Joyce, GrĂ©goire Mathys, | Summary: We study effective field theories (EFTs) enjoying (maximal) biform symmetries. These are defined by the presence of a conserved (electric) current that has the symmetries of a Young tableau with two columns of equal length. When […]

Sunyaev-Zel’dovich effect and X-ray scaling relations of galaxies, groups and clusters in the IllustrisTNG simulations

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Ana-Roxana Pop, Lars Hernquist, Daisuke Nagai, Rahul Kannan, Rainer Weinberger | Summary: Observable thermodynamical properties of the intracluster medium (ICM) reflect the complex interplay between AGN feedback and the gravitational collapse of haloes. Using the large volume TNG300 simulation of the IllustrisTNG project we provide predictions for […]
