DOI: 10.1038/s41586-021-03409-2
Abstract: In condensed-matter systems, higher temperatures typically disfavour ordered phases, leading to an upper critical temperature for magnetism, superconductivity and other phenomena. An exception is the Pomeranchuk effect in 3He, in which the liquid ground state… read more here.

DOI: 10.1103/physrevc.100.045201
Abstract: We study the Kondo effect for a Σc (Σ ∗ c) baryon in nuclear matter. In terms of the spin and isospin (SU(2)spin × SU(2)isospin) symmetry, the heavy-quark spin symmetry and the S-wave interaction, we… read more here.

DOI: 10.1103/physrevd.107.074027
Abstract: We use the two-flavor linear sigma model with quarks to study the phase structure of isospin asymmetric matter at zero temperature. The meson degrees of freedom provide the mean field chiral- and isospin-condensates on top… read more here.
