The axion-photon coupling from lattice Quantum Chromodynamics
Bastian B. Brandt, Gergely EndrÅdi, José Javier Hernández Hernández +2
Quantum Chromodynamics (QCD) is the theory of the strong interactions within the Standard Model of particle physics, which explains more than 99% of the mass of the visible Univers…
Spectral reconstruction techniques, their shortcomings and relevance to the electric conductivity coefficient
C. Andratschke, B. B. Brandt, E. Garnacho-Velasco +3
Spectral reconstruction is a well studied numerically ill-posed problem which arises due to the relation of the Euclidean correlator to the spectral function via an inhomogeneous F…
Dilepton production from moaton quasiparticles
Zohar Nussinov, Michael C. Ogilvie, Laurin Pannullo +4
The phase diagram of QCD may contain a moat regime in a large region of temperature and chemical potential . A moat regime is characterized by quasiparticle moatons (p…
Constraining fermionic condensates
Gergely EndrÅdi, Tamás G. Kovács, Gergely Markó +1
We study spontaneous symmetry breaking in quantum field theories with fermionic order parameters and construct, for the first time in the literature, the constraint effective poten…
Regularization effects in the Nambu-Jona-Lasinio model: Strong scheme dependence of inhomogeneous phases and persistence of the moat regime
Laurin Pannullo, Marc Wagner, Marc Winstel
This work investigates the phase structure of the non-renormalizable (3+1)-dimensional Nambu-Jona-Lasinio (NJL) model with particular focus on inhomogeneous phases (IPs), where the…
