Abstract: Abstract We study different aspects of quantum field theory at finite density using methods from quantum information theory. For simplicity we focus on massive Dirac fermions with nonzero chemical potential, and work in 1 +… read more here.

Abstract: We construct the first analytic examples of non-homogeneous condensates in the Georgi-Glashow model at finite density in (2 + 1) dimensions. The non-homogeneous condensates, which live within a cylinder of finite spatial volume, possess a… read more here.

DOI: 10.1103/physrevd.99.074514
Abstract: 2-color QCD is the simplest QCD-like theory which is accessible to lattice simulations at finite density. It therefore plays an important role to test qualitative features and to provide benchmarks to other methods and models,… read more here.

DOI: 10.1103/physrevd.99.114510
Abstract: We study different estimators of the radius of convergence of the Taylor series of the pressure in finite density QCD. We adopt the approach in which the radius of convergence is estimated first in a… read more here.
