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…
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…
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…
Dihedral Lattice Gauge Theories on a Quantum Annealer
Michael Fromm, Owe Philipsen, Christopher Winterowd
We study lattice gauge theory with discrete, non-Abelian gauge groups. We extend the formalism of previous studies on D-Wave's quantum annealer as a computing platform to finite, s…
Onset Transition to Cold Nuclear Matter from Lattice QCD with Heavy Quarks to
Jens Langelage, Mathias Neuman, Owe Philipsen
We present results of our ongoing studies of an effective three-dimensional theory of thermal lattice QCD with heavy Wilson quarks. This is done by combined strong coupling and hop…
Phase transitions in heavy-quark QCD from an effective theory
Michael Fromm, Jens Langelage, Stefano Lottini +2
With combined hopping parameter and strong coupling expansions, we calculate a dimensionally reduced Polyakov-loop effective theory valid for heavy quarks at nonzero temperature an…
Onset Transition to Cold Nuclear Matter from Lattice QCD with Heavy Quarks
Michael Fromm, Jens Langelage, Stefano Lottini +2
Lattice QCD at finite density suffers from a severe sign problem, which has so far prohibited simulations of the cold and dense regime. Here we study the onset of nuclear matter em…
Strong coupling effective theory with heavy fermions
Michael Fromm, Jens Langelage, Stefano Lottini +1
We extend the recently developed strong coupling, dimensionally reduced Polyakov-loop effective theory from finite-temperature pure Yang-Mills to include heavy fermions and nonzero…
The QCD deconfinement transition for heavy quarks and all baryon chemical potentials
Michael Fromm, Jens Langelage, Stefano Lottini +1
Using combined strong coupling and hopping parameter expansions, we derive an effective three-dimensional theory from thermal lattice QCD with heavy Wilson quarks. The theory depen…
Towards corrections to the strong coupling limit of staggered lattice QCD
Philippe de Forcrand, Michael Fromm, Jens Langelage +3
We report on the first steps of an ongoing project to add gauge observables and gauge corrections to the well-studied strong coupling limit of staggered lattice QCD, which has been…
Nuclear physics from strong coupling QCD
Michael Fromm, Philippe de Forcrand
The strong coupling limit (beta_gauge = 0) of QCD offers a number of remarkable research possibilities, of course at the price of large lattice artifacts. Here, we determine the co…
Nuclear Physics from lattice QCD at strong coupling
Philippe de Forcrand, Michael Fromm
We study numerically the strong coupling limit of lattice QCD with one flavor of massless staggered quarks. We determine the complete phase diagram as a function of temperature and…
Revisiting strong coupling QCD at finite temperature and baryon density
M. Fromm, Ph. de Forcrand
The strong coupling limit () of lattice QCD with staggered fermions enjoys the same non-perturbative properties as continuum QCD, namely confinement and chiral symmetr…
