Theory of magnetic field-induced metaelectric critical end point in BiMnO
Gun Sang Jeon, Jin-Hong Park, Kee Hoon Kim +1
A recent experiment on the multiferroic BiMnO compound under a strong applied magnetic field revealed a rich phase diagram driven by the coupling of magnetic and charge (di…
Observation of a multiferroic critical end point
Jae Wook Kim, S. Y. Haam, Y. S. Oh +9
The study of abrupt increases in magnetization with magnetic field known as metamagnetic transitions has opened a rich vein of new physics in itinerant electron systems, including…
Relaxation dynamics and interrupted coarsening in irrationally frustrated superconducting arrays
Gun Sang Jeon, Sung Jong Lee, Bongsoo Kim +1
Equilibrium and non-equilibrium relaxation behaviors of two-dimensional superconducting arrays are investigated via numerical simulations at low temperatures in the presence of inc…
Semiconductor quantum dots in high magnetic fields: The composite-fermion view
Gun Sang Jeon, Chia-Chen Chang, Jainendra K. Jain
We review and extend the composite fermion theory for semiconductor quantum dots in high magnetic fields. The mean-field model of composite fermions is unsatisfactory for the quali…
Near-field Optical Spectroscopy and Microscopy of Laterally Coupled Quantum Dots: Bonding and Antibonding States
Young-Jun Yu, Haneol Noh, Gun Sang Jeon +2
We report on high-resolution photoluminescence (PL) spectroscopic and microscopic study of laterally coupled InAs/GaAs self-assembled quantum dots by using a low-temperature near-f…
