Doubly heavy tetraquarks in a chiral-diquark picture
Yonghee Kim, Makoto Oka, Kei Suzuki
Energy spectrum of doubly heavy tetraquarks, ( with and ), is studied in the potential chiral-diquark model. Using the chiral e…
Heavy baryon spectrum with chiral multiplets of scalar and vector diquarks
Yonghee Kim, Yan-Rui Liu, Makoto Oka +1
Chiral effective theory of scalar and vector diquarks is formulated according to the linear sigma model. The main application is to describe the ground and excited states of singly…
Spectrum of singly heavy baryons from a chiral effective theory of diquarks
Yonghee Kim, Emiko Hiyama, Makoto Oka +1
The mass spectra of singly charmed and bottom baryons, and , are investigated using a nonrelativistic potential model with a heavy…
Nonlinear, Nonequilibrium and Collective Dynamics in a Periodically Modulated Cold Atom System
Geol Moon, Myoung-Sun Heo, Yonghee Kim +2
The physics of critical phenomena in a many-body system far from thermal equilibrium is an interesting and important issue to be addressed both experimentally and theoretically. Th…
An Ideal Mean-Field Transition in a Modulated Cold Atom System
Myoung-Sun Heo, Yonghee Kim, Kihwan Kim +5
We show that an atomic system in a periodically modulated optical trap displays an ideal mean-field symmetry-breaking transition. The symmetry is broken with respect to time transl…
