Resonances at finite temperature from the lattice
Jakob Hoffmann, Peter Lowdon, Owe Philipsen
The properties of hadronic resonances at finite temperature constitute an important probe of the thermal QCD medium. In this work we use the concept of thermoparticles, which chara…
On the phase structure of massless many-flavour QCD with staggered fermions
Jan Philipp Klinger, Reinhold Kaiser, Owe Philipsen +1
When the number of massless fermions exceeds a critical value , QCD enters the conformal window and becomes chirally symmetric already in the vacuum. Determining fro…
On the nature of the QCD chiral phase transition with imaginary chemical potential
Alfredo D'Ambrosio, Michael Fromm, Reinhold Kaiser +1
The order of the thermal chiral phase transition in lattice QCD is known to be strongly cutoff-dependent. A previous study using mass-degenerate, unimproved…
From deconfinement to nuclear matter: mean-field approaches for effective Polyakov loop theories of lattice QCD
Christoph Konrad, Owe Philipsen
Numerical studies of the QCD phase diagram at finite baryon chemical potential on the lattice are impeded by a sign problem. Effective Polyakov loop theories derived from lat…
Lattice Monte Carlo meets lattice functional Renormalization Group: A quantitative comparison
Niklas Zorbach, Jan Philipp Klinger, Owe Philipsen +1
Lattice Monte Carlo (MC) simulations and the functional Renormalization Group (RG) are powerful approaches that allow for quantitative studies of non-perturbative phenomena such as…
Pion condensation at non-zero isospin chemical potential with Wilson fermions
Rocco Francesco Basta, Bastian B. Brandt, Francesca Cuteri +2
In contrast to the case of non-zero baryon chemical potential, the isospin chemical potential does not introduce a sign problem and can be simulated on the lattice. When the isospi…

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…
Quantum computational resources for lattice QCD in the strong-coupling limit
Michael Fromm, Lucas Katschke, Owe Philipsen +1
We consider the strong coupling limit of lattice QCD with massless staggered quarks and study the resource requirements for quantum simulating the theory in its Hamiltonian formula…
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…
Quantum Gate Sets for Lattice QCD in the strong coupling limit:
Michael Fromm, Owe Philipsen, Wolfgang Unger +1
We derive the primitive quantum gate sets to simulate lattice quantum chromodynamics (LQCD) in the strong-coupling limit with one flavor of massless staggered quarks. This theory i…
Simulating Lattice Gauge Theory with the Variational Quantum Thermalizer
Michael Fromm, Owe Philipsen, Michael Spannowsky +1
The properties of strongly-coupled lattice gauge theories at finite density as well as in real time have largely eluded first-principles studies on the lattice. This is due to the…

Gert Aarts, Joerg Aichelin, Chris Allton +38
Phase transitions in a non-perturbative regime can be studied by ab initio Lattice Field Theory methods. The status and future research directions for LFT investigations of Quantum…

The thermodynamics of QCD with sufficiently heavy dynamical quarks can be described by a three-dimensional Polyakov loop effective theory, obtained after a truncated character and…

For the exploration of the phase diagram of QCD, effective Polyakov loop theories derived from lattice QCD provide a valuable tool in the heavy quark mass regime. In practice, the…
The chiral phase transition at non-zero imaginary baryon chemical potential for different numbers of quark flavours
Alfredo D'Ambrosio, Owe Philipsen, Reinhold Kaiser
The so-called Columbia plot summarises the order of the QCD thermal transition as a function of the number of quark flavours and their masses. Recently, it was demonstrated that th…

Reinhold Kaiser, Owe Philipsen
The global center symmetry of quenched QCD at zero baryonic chemical potential is broken spontaneously at a critical temperature leading to a first-order phase transition. In…

Non-perturbative insights into the spectral properties of QCD at finite temperature
Peter Lowdon, Owe Philipsen
In quantum field theories at finite temperature spectral functions describe how particle systems behave in the presence of a thermal medium. Although data from lattice simulations…
Pion spectral properties above the chiral crossover of QCD
Peter Lowdon, Owe Philipsen
Spectral functions encode a wealth of information about the dynamics of any given system, and the determination of their non-perturbative characteristics is a long-standing problem…
