Inter-valley coherent order and isospin fluctuation mediated superconductivity in rhombohedral trilayer graphene. [PDF]
Nat Commun, 2022 Superconductivity was recently discovered in rhombohedral trilayer graphene (RTG) in the absence of a moiré potential. Superconductivity is observed proximate to a metallic state with reduced isospin symmetry, but it remains unknown whether this is a ...

The isospin and compositeness of the $$T_{cc}(3875)$$ T cc ( 3875 ) state [PDF]
European Physical Journal C: Particles and Fields, 2023 We perform a fit to the LHCb data on the $$T_{cc}(3875)$$ T cc ( 3875 ) state in order to determine its nature. We use a general framework that allows to have the $$D^0 D^{*+},$$ D 0 D ∗ + , $$D^+ D^{*0}$$ D + D ∗ 0 components forming a molecular state ...

Isospin Effect on Baryon and Charge Fluctuations from the pNJL Model
Universe, 2020 We have studied the possible isospin corrections on the skewness and kurtosis of net-baryon and net-charge fluctuations in the isospin asymmetric matter formed in relativistic heavy-ion collisions at RHIC-BES energies, based on a 3-flavor Polyakov-looped

Isospin symmetry of fragmentation functions [PDF]
Physics Letters B, 2021 We make a systematic study of the isospin symmetry of fragmentation functions by taking decay contributions into account. We assume the isospin symmetry in strong interactions and show that in the unpolarized case the isospin symmetry is held for ...

Isospin-Symmetry Breaking within the Nuclear Shell Model: Present Status and Developments
Physics, 2023 The paper reviews the recent progress in the description of isospin-symmetry breaking within the nuclear shell model and applications to actual problems related to the structure and decay of exotic neutron-deficient nuclei and nuclei along the N=Z line ...

Isospin asymmetry in holographic baryonic matter [PDF]
SciPost Physics, 2021 We study baryonic matter with isospin asymmetry, including fully dynamically its interplay with pion condensation. To this end, we employ the holographic Witten-Sakai-Sugimoto model and the so-called homogeneous ansatz for the gauge fields in the bulk

Finite-density massless two-color QCD at the isospin Roberge-Weiss point and the 't Hooft anomaly
Physical Review Research, 2020 We study the phase diagram of two-flavor massless two-color QCD (QC_{2}D) under the presence of quark chemical potentials and imaginary isospin chemical potentials.

Thermodynamics and susceptibilities of isospin imbalanced QCD matter [PDF]
European Physical Journal C: Particles and Fields, 2020 We study the thermodynamics and the susceptibilities of quark matter in the framework of two-flavor Nambu–Jona–Lasinio model at finite isospin chemical potential and temperature.

Isospin-symmetry breaking in superallowed Fermi β-decay due to isospin-nonconserving forces
Physics Letters B, 2017 We investigate isospin-symmetry breaking effects in the sd-shell region with large-scale shell-model calculations, aiming to understand the recent anomalies observed in superallowed Fermi β-decay.

Isospin magnetism and spin-polarized superconductivity in Bernal bilayer graphene [PDF]
Science, 2021 In conventional superconductors, Cooper pairing occurs between electrons of opposite spin. We observe spin-polarized superconductivity in Bernal bilayer graphene when doped to a saddle-point van Hove singularity generated by a large applied perpendicular
