Superfluid flow above the critical velocity by A. Paris-Mandoki, J. Shearring, F. Mancarella, T. M. Fromhold, A. Trombettoni, P. Krüger

“…Abstract Superfluidity and superconductivity have been widely studied since the last century in many different contexts ranging from nuclear matter to atomic quantum gases. The rigidity of these systems with respect to external perturbations results in frictionless motion for superfluids and resistance-free electric current flow in superconductors. …”

Flavor hierarchy of parton energy loss in quark-gluon plasma from a Bayesian analysis by Wen-Jing Xing, Shanshan Cao, Guang-You Qin

“…We find that the average parton energy loss at high energies follows the expected hierarchy of 〈ΔEg〉>〈ΔEq〉∼〈ΔEc〉>〈ΔEb〉, while the parton energy loss distribution can further test the QCD calculations of parton interaction with the dense nuclear matter. We also find that the reduction of experimental uncertainties can significantly improve the precision of the extracted parton energy loss functions inside the QGP.…”

Impact of different components of the Skyrme nucleon–nucleon effective interaction on the nuclear density distribution by W. M. Seif, A. S. Hashem

“…Abstract We systematically investigate the impact of the different terms of the Skyrme energy density functional of the effective nucleon-nucleon interaction, and of its associated nuclear matter (NM) properties, on the density distributions of spherical nuclei. …”

Mapping Topology of Skyrmions and Fractional Quantum Hall Droplets to Nuclear EFT for Ultra-Dense Baryonic Matter by Mannque Rho

“…The theory constructed is found to be consistent with no conflicts with the presently available observations in both normal nuclear matter and compact-star matter. The hidden symmetries involved are “local flavor symmetry” of the vector mesons identified to be (Seiberg-)dual to the gluons of QCD and hidden “quantum scale symmetry” with an IR fixed point with a “genuine dilaton (GD)” characterized by non-vanishing pion and dilaton decay constants. …”

Strange Hadron Production in Au+Au Collisions at √SNN = 54.4 GeV by Huang Yan

“…As a sensitive probe to the transition from the hadron gas to the Quark-Gluon Plasma, the particle ratios of strange hadrons are measured to study the properties of nuclear matter. Recently, the production of strange hadrons (KS0, Λ, Ξ, Ω, and ϕ)$\left({K_S^0,\Lambda ,\Xi ,\Omega ,\,{\rm{and}}\,\phi } \right)$(KS0,Λ,Ξ,Ω, and ϕ) at mid-rapidity (|y|<0.5) in Au+Au collisions at √SNN = 54.4 GeV$\sqrt {{S_{{\rm{NN}}}}} = 54.4\,{\rm{GeV}}$SNN=54.4 GeV were measured by the STAR experiment at RHIC. …”

Weighing massive neutron star with screening gravity: a look on PSR J0740 + 6620 and GW190814 secondary component by Rafael C. Nunes, Jaziel G. Coelho, José C. N. de Araujo

“…Abstract Neutron stars (NSs) are excellent natural laboratories to constrain gravity on strong field regime and nuclear matter in extreme conditions. Motivated by the recent discovery of a compact object with $$2.59^{+0.08}_{-0.09} M_\odot $$ 2 . 59 - 0.09 + 0.08 M ⊙ in the binary merger GW190814, if this object was a NS, it serves as a strong constraint on the NS equation of state (EoS), ruling out several soft EoSs favored by GW170817 event. …”

Directed and elliptic flows of protons and deuterons in HADES Au+Au collisions at sNN=2.4 GeV by Huan Du, Gao-Feng Wei, Gao-Chan Yong

Λ⁎(1405)-matter: Stable or unstable? by J. Hrtánková, N. Barnea, E. Friedman, A. Gal, J. Mareš, M. Schäfer

“…The central density of Λ⁎ matter is found to saturate as well, at roughly twice nuclear matter density. Moreover, it is shown that the underlying very strong K¯N potentials, fitted for isospin I=0 to the mass and width values of Λ⁎(1405), fail to reproduce values of single-nucleon absorption fractions deduced across the periodic table from K− capture-at-rest bubble chamber experiments. …”

Uncertainties in WIMP dark matter scattering revisited by John Ellis, Natsumi Nagata, Keith A. Olive

“…Abstract We revisit the uncertainties in the calculation of spin-independent scattering matrix elements for the scattering of WIMP dark matter particles on nuclear matter. In addition to discussing the uncertainties due to limitations in our knowledge of the nucleonic matrix elements of the light quark scalar densities $$\langle N |{{{\bar{u}}}} u, {{{\bar{d}}}} d, {{{\bar{s}}}} s| N \rangle $$ ⟨N|u¯u,d¯d,s¯s|N⟩ , we also discuss the importances of heavy quark scalar densities $$\langle N |{{{\bar{c}}}} c, {{{\bar{b}}}} b, {{{\bar{t}}}} t| N \rangle $$ ⟨N|c¯c,b¯b,t¯t|N⟩ , and comment on uncertainties in quark mass ratios. …”

Thermography of the superfluid transition in a strongly interacting Fermi gas by Yan, Zhenjie, Patel, Parth B., Mukherjee, Biswaroop, Vale, Chris J., Fletcher, Richard J., Zwierlein, Martin

“…Here we establish thermography of a strongly interacting atomic Fermi gas, a paradigmatic system whose properties relate to strongly correlated electrons, nuclear matter and neutron stars. Just as the color of a glowing metal reveals its temperature, the radiofrequency spectrum of the interacting Fermi gas provides spatially resolved thermometry with sub-nanokelvin resolution. …”

Progress in Constraining Nuclear Symmetry Energy Using Neutron Star Observables Since GW170817 by Bao-An Li, Bao-Jun Cai, Wen-Jie Xie, Nai-Bo Zhang

“…The density dependence of nuclear symmetry energy is among the most uncertain parts of the Equation of State (EOS) of dense neutron-rich nuclear matter. It is currently poorly known especially at suprasaturation densities partially because of our poor knowledge about isovector nuclear interactions at short distances. …”

Constraints on the symmetry energy from PREX-II in the multimessenger era by Tong-Gang Yue, Lie-Wen Chen, Zhen Zhang, Ying Zhou
