Anderson transition of in-gap quasiparticles in a quasi-two-dimensional disordered superconductor
Hae-Ryong Park, Kyung-Yong Park, Kyoung-Min Kim +4
The Anderson transition of Bogoliubov-de Gennes (BdG) quasiparticles in superconducting state has been studied theoretically for last three decades. However, its experimental proof…
Quantum phase transition from a paramagnetic Anderson insulating state to a ferromagnetic many-body localized state via an intermediate ferromagnetic metallic phase
Kyung-Yong Park, Iksu Jang, Ki-Seok Kim
Effects of electron correlations on Anderson insulators have been one of the central themes for recent two decades, suggesting that the Anderson insulating phase turns into a novel…
Inhomogeneous Kondo destruction by RKKY correlations
Kyung-Yong Park, Iksu Jang, Ki-Seok Kim +1
The competition between the indirect exchange interaction (IEC) of magnetic impurities in metals and the Kondo effect gives rise to a rich quantum phase diagram, the Doniach Diagra…
Half metals at intermediate energy scales in Anderson-type insulators
Kyung-Yong Park, Hyun-Jung Lee, Ki-Seok Kim
Although quantum phase transitions involved with Anderson localization had been investigated for more than a half century, the role of spin polarization in these metal-insulator tr…
