A lattice pairing-field approach to ultracold Fermi gases
Florian Ehmann, Joaquín E. Drut, Jens Braun
We develop a pairing-field formalism for ab initio studies of non-relativistic two-component fermions on a -dimensional spacetime lattice. More specifically, we focus on…
Renormalised spectral flows
Jens Braun, Yong-rui Chen, Wei-jie Fu +11
We derive renormalised finite functional flow equations for quantum field theories in real and imaginary time that incorporate scale transformations of the renormalisation conditio…
Speed of sound in dense strong-interaction matter
Jens Braun, Andreas Geißel, Benedikt Schallmo
We study the speed of sound in strong-interaction matter at zero temperature and in density regimes which are expected to be governed by the presence of a color-superconducting gap…
Zero-temperature thermodynamics of dense asymmetric strong-interaction matter
Jens Braun, Benedikt Schallmo
Employing constraints derived from the microscopic theory of the strong interaction, we estimate the zero-temperature phase structure of dense isospin-asymmetric matter with two qu…
Pairing patterns in polarized unitary Fermi gases above the superfluid transition
Felipe Attanasio, Lukas Rammelmüller, Joaquín E. Drut +1
We non-perturbatively study pairing in the high-temperature regime of polarized unitary two-component Fermi gases by extracting the pair-momentum distribution and shot-noise correl…
Numerical fluid dynamics for FRG flow equations: Zero-dimensional QFTs as numerical test cases. II. Entropy production and irreversibility of RG flows
Adrian Koenigstein, Martin J. Steil, Nicolas Wink +2
We demonstrate that the reformulation of renormalization group (RG) flow equations as non-linear heat equations has severe implications on the understanding of RG flows in general.…
