    The role of the pion mass on the QCD phase diagram in the plane

    Chowdhury Aminul Islam🇩🇪 · Mahammad Sabir Ali🇮🇳 · Rishi Sharma🇮🇳

    We investigated the role of the pion mass on the QCD phase diagram in the plane using an effective model treatment. Such treatments are able to capture the main features predicted by first-principles calculations. We also employed the model to estimate the pion mass beyond which the inverse magnetic catalysis (IMC) effect disappears. The value is found to be independent of the strength of the magnetic field.

    The Renormalized Yukawa Hamiltonian: Spectrum, Parton Distribution Functions, and Resource Estimates for Quantum Simulation

    Carter M. Gustin🇺🇸 · Kamil Serafin🇺🇸 · William A. Simon🇺🇸 · Alexis Ralli🇺🇸 · Gary R. Goldstein🇺🇸 · Peter J. Love🇺🇸

    We apply the Renormalization Group Procedure for Effective Particles (RGPEP) to the front form Yukawa Hamiltonian, yielding a renormalized (effective) Hamiltonian, accurate up to second order in the coupling strength. Subsequently, we examine the spectrum and parton distribution functions produced by the renormalized Hamiltonian, and show that the addition of counterterms leads to finite results. Resource estimates for quantum simulation are calculated for a single `Ladder Operator Block Encoding' (LOBE), and show that the cost to block encode the renormalized Hamiltonian is comparable to block encoding the bare Hamiltonian.
