in iso-symmetric QCD and the CKM matrix unitarity
Alessandro Conigli, Julien Frison, Alejandro Sáez
We present lattice results for in the iso-symmetric limit of pure QCD (isoQCD) with flavours, along with a determination of and a study on t…
The quest for the quark-gluon plasma from the perspective of dynamical models of relativistic heavy-ion collisions
Marcus Bleicher, Elena Bratkovskaya
The physics of heavy-ion collisions is one of the most exciting and challenging directions of science for the last four decades. On the theoretical side one deals with a non-abelia…
The order of the chiral phase transition in massless many-flavour lattice QCD
Jan Philipp Klinger, Reinhold Kaiser, Owe Philipsen
The nature of the QCD phase transition in the chiral limit presents a challenging problem for lattice QCD. However, its study provides constraints on the phase diagram at the physi…
Warm Start of Variational Quantum Algorithms for Quadratic Unconstrained Binary Optimization Problems
Yahui Chai, Karl Jansen, Stefan Kühn +2
Variational Quantum Eigensolver (VQE) is widely used in near-term hardware. However, their performances remain limited by the poor trainability and are dependent on random paramete…
On the (in)consistency of perturbation theory at finite temperature
Peter Lowdon, Owe Philipsen
A well-known difficulty of perturbative approaches to quantum field theory at finite temperature is the necessity to address theoretical constraints that are not present in the vac…
Pseudo-scalar meson spectral properties in the chiral crossover region of QCD
Dibyendu Bala, Olaf Kaczmarek, Peter Lowdon +2
Determining the type of excitations that can exist in a thermal medium is key to understanding how hadronic matter behaves at extreme temperatures. In this work we study this quest…
