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 (pi…
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…
Revisiting the spatially inhomogeneous condensates in the -dimensional chiral Gross-Neveu model via the bosonic two-point function in the infinite- limit
Adrian Koenigstein, Marc Winstel
This work shows that the known phase boundary between the phase with chiral symmetry and the phase of spatially inhomogeneous chiral symmetry breaking in the phase diagram of the $…
Lattice study of disordering of inhomogeneous condensates and the Quantum Pion Liquid in effective model
Marc Winstel, Semeon Valgushev
In this talk, we study a scalar model with a so-called moat regime -- a regime with negative bosonic wave function renormalization -- using lattice field theory. For negativ…
Spatially oscillating correlation functions in -dimensional four-fermion models: The mixing of scalar and vector modes at finite density
Marc Winstel
In this work, we demonstrate that the mixing of scalar and vector condensates produces spatially oscillating, but exponentially damped correlation functions in fermionic theories a…
Absence of inhomogeneous chiral phases in 2+1-dimensional four-fermion and Yukawa models
Laurin Pannullo, Marc Winstel
We show the absence of an instability of homogeneous (chiral) condensates against spatially inhomogeneous perturbations for various 2+1-dimensional four-fermion and Yukawa models.…

Laurin Pannullo, Marc Wagner, Marc Winstel
In this work we study the -dimensional Nambu-Jona-Lasinio (NJL) model in the mean field-approximation. We carry out calculations using five different regularization schemes (t…
Stability of homogeneous chiral phases against inhomogeneous perturbations in 2+1 dimensions
Marc Winstel, Laurin Pannullo
In this work, inhomogeneous chiral phases are studied in a variety of Four-Fermion and Yukawa models in dimensions at zero and non-zero temperature and chemical potentials. E…
Inhomogeneous phases in the chirally imbalanced -dimensional Gross-Neveu model and their absence in the continuum limit
Laurin Pannullo, Marc Wagner, Marc Winstel
We study the -- phase diagram of the -dimensional Gross-Neveu model, where denotes the ordinary chemical potential, the chiral chemical potential an…
Detecting inhomogeneous chiral condensation from the bosonic two-point function in the -dimensional Gross-Neveu model in the mean-field approximation
Adrian Koenigstein, Laurin Pannullo, Stefan Rechenberger +2
The phase diagram of the -dimensional Gross-Neveu model is reanalyzed for (non-)zero chemical potential and (non-)zero temperature within the mean-field approximation. By…
Phase diagram of the 2+1-dimensional Gross-Neveu model with chiral imbalance
Marc Winstel, Laurin Pannullo, Marc Wagner
In this work, the phase diagram of the -dimensional Gross-Neveu model is investigated with baryon chemical potential as well as chiral chemical potential in the mean-field app…

Michael Buballa, Lennart Kurth, Marc Wagner +1
The phase diagram of the Gross-Neveu model in space-time dimensions at non-zero temperature and chemical potential is studied in the limit of infinitely many flavors, focusin…
Lattice investigation of an inhomogeneous phase of the 2+1-dimensional Gross-Neveu model in the limit of infinitely many flavors
Marc Winstel, Jonas Stoll, Marc Wagner
We investigate the phase structure of the 2+1-dimensional Gross-Neveu model in the large-Nf limit, where Nf denotes the number of fermion flavors. We discuss two different fermion…
