18. The Kondo effect in dense QCD

Dr Koichi Hattori (Yukawa Institute, Kyoto University)

Oral talk

We discuss Kondo effect occurring in dense QCD [1,2]. Based on the renormalization-group analysis, we show that effective coupling strengths between ungapped and gapped quarks in the two-flavor color superconducting (2SC) phase are renormalized by logarithmic quantum corrections, which drives the system into a strongly coupled regime [2]. This is a characteristic behavior observed in the Kondo...

40. Non-Abelian vortices in dense QCD: quark-hadron continuity and non-Abelian statistics

Prof. Muneto Nitta (Keio University)

Oral talk

Quark-hadron continuity was proposed as crossover between hadronic matter and quark matter without a phase transition, based on the matching of the symmetry and excitations in both phases. In the limit of a light strange-quark mass, it connects hyperon matter and the color-flavor-locked phase exhibiting color superconductivity. Here, we argue that three hadronic superfluid vortices must...

44. Quark-hadron continuity beyond Ginzburg-Landau paradigm

Dr Yuji Hirono (Asia Pacific Center for Theoretical Physics)

Oral talk

Quark-hadron continuity [1] is a scenario that hadronic matter is continuously connected to color superconductor without phase transitions as the baryon chemical potential increases. This scenario is based on Landau's classification of phases since they have the same symmetry breaking pattern. We address the question whether this continuity is true as quantum phases of matter, which requires...
