Towards quantitative precision in ultracold atoms with functional renormalisation
Bruno M. Faigle-Cedzich, Jan M. Pawlowski, Christof Wetterich
We compute the equation of state, the gap as well as the density fluctuations of a two-component superfluid Fermi gas over the whole range of BEC-BCS crossover at vanishing tempera…
Scaling solutions for asymptotically free quantum gravity
Saswato Sen, Christof Wetterich, Masatoshi Yamada
We compute scaling solutions of functional flow equations for quantum gravity in a general truncation with up to four derivatives of the metric. They connect the asymptotically fre…
Coupled and uncoupled early dark energy, massive neutrinos and the cosmological tensions
Adrià Gómez-Valent, Ziyang Zheng, Luca Amendola +2
Some cosmological models with non-negligible dark energy fractions in particular windows of the pre-recombination epoch are capable of alleviating the Hubble tension quite efficien…
Gluon condensates and effective gluon mass
Jan Horak, Friederike Ihssen, Joannis Papavassiliou +3
Lattice simulations along with studies in continuum QCD indicate that non-perturbative quantum fluctuations lead to an infrared regularisation of the gluon propagator in covariant…
Asymptotic freedom and safety in quantum gravity
Saswato Sen, Christof Wetterich, Masatoshi Yamada
We compute non-perturbative flow equations for the couplings of quantum gravity in fourth order of a derivative expansion. The gauge invariant functional flow equation for arbitrar…
Early dark energy in the pre- and post-recombination epochs
Adrià Gómez-Valent, Ziyang Zheng, Luca Amendola +2
Many quintessence models possess scaling or attractor solutions where the fraction of dark energy follows the dominant component in previous epochs of the expansion, or phase trans…
