Hadronic Molecules and Coupled States
Kotaro Miyake, Yasuhiro Yamaguchi
We investigate hidden-charm exotic mesons based on a coupled-channel framework, where the physical states are described as superpositions of a compact core (identified wi…

Emergent spin- Haldane gap and ferroelectricity in a frustrated spin- ladder
Hiroshi Ueda, Shigeki Onoda, Yasuhiro Yamaguchi +19
We report experimental and theoretical evidence that RbCuMoO has a nonmagnetic tetramer ground state of a two-leg ladder comprising antiferromagnetically coupled…
