Exact Lattice Identities and Continuum-Limit Dyson--Schwinger Equations for Yang-Mills Theory
Arpan Chatterjee, Marco Frasca, Anish Ghoshal +1
Starting from SU(N) on the lattice, we give a rigorous derivation of the Dyson--Schwinger equations in the continuum limit. We formulate the Dyson--Schwinger identities for the lat…
Review of strongly coupled regimes in gravity with Dyson-Schwinger approach
Marco Frasca, Anish Ghoshal
We analyze various gravity theories involving de-Sitter, quadratic and non-minimally coupled scalar in the light of application of the Dyson-Schwinger technique inv…
Quintessence Dark Energy from non-perturbative Higgs-Yang-Mills mass gap
Marco Frasca, Anish Ghoshal, Massimiliano Rinaldi
We discuss the equations that arise from a Higgs--Yang-Mills dark sector coupled to gravity on a flat Friedmann-Lemaitre-Robinson-Walker metric. We choose the simplest repr…
Finite temperature QCD crossover at non-zero chemical potential: A Dyson-Schwinger approach
Arpan Chatterjee, Marco Frasca, Anish Ghoshal +1
We study QCD at finite temperature and non-zero chemical potential to derive the critical temperature at the chiral phase transition (crossover). We solve a set of Dyson--Schwinger…
Mass gap in non-perturbative quadratic gravity via Dyson-Schwinger
Sayantan Choudhury, Marco Frasca, Anish Ghoshal
We apply in a simple model derived from quadratic gravity the technique of Dyson-Schwinger equations to solve for its corresponding quantum theory. Particularly, we…
Non-perturbative Origin of the Electroweak Scale with Dyson-Schwinger: Fermionic Mass Gap and Higher-order Excitations
Marco Frasca, Anish Ghoshal, Nobuchika Okada
We study interaction of a fermion field with a scalar field and analyze the spectrum of the theory obtained in this way. It is shown that due to non-perturbative dynamics i…
