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 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 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

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.

Mesonic condensation in isospin matter under rotation * [PDF]
, 2020 We investigate mesonic condensation in isospin matter under rotation. Using the two-flavor NJL effective model in the presence of global rotation, we demonstrate two important effects of rotation on its phase structure: a rotational suppression of the ...

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

Quark mass dependence of ππ scattering in isospin 0, 1, and 2 from lattice QCD [PDF]
Physical Review D, 2023 Using lattice QCD we extract $\pi\pi$ scattering amplitudes with isospin--0,1,2 in low partial-waves at two values of the light quark mass corresponding to $m_\pi \sim 283$ and $330$ MeV.
