Competing states for the fractional quantum Hall effect in the 1/3-filled second Landau level
Jae-Seung Jeong, Hantao Lu, Ki Hoon Lee +3
In this work, we investigate the nature of the fractional quantum Hall state in the 1/3-filled second Landau level (SLL) at filling factor (and 8/3 in the presence of the p…
Bilayer mapping of the paired quantum Hall state: Instability toward anisotropic pairing
Jae-Seung Jeong, Kwon Park
One of the most dominant candidates for the paired quantum Hall (QH) state at filling factor is the Moore-Read (MR) Pfaffian state. A salient problem, however, is that it d…
Emergent quantum phases in a frustrated J1-J2 Heisenberg model on hyperhoneycomb lattice
SungBin Lee, Jae-Seung Jeong, Kyusung Hwang +1
We investigate possible quantum ground states as well as the classical limit of a frustrated J1-J2 Heisenberg model on the three-dimensional (3D) hyperhoneycomb lattice. Our study…
Curvature-induced spin-orbit coupling and spin relaxation in a chemically clean single-layer graphene
Jae-Seung Jeong, Jeongkyu Shin, Hyun-Woo Lee
The study of spin-related phenomena in materials requires knowledge on the precise form of effective spin-orbit coupling of conducting carriers in the solid-states systems. We demo…
Suppression of Spin Dephasing in a Two-Dimensional Electron Gas with a Quantum Point Contact
Jae-Seung Jeong, Hyun-Woo Lee
Spin-orbit coupling is a source of strong spin dephasing in two- and three-dimensional semiconducting systems. We report that spin dephasing in a two-dimensional electron gas can b…
Curvature-enhanced spin-orbit coupling in a carbon nanotube
Jae-Seung Jeong, Hyun-Woo Lee
Structure of the spin-orbit coupling varies from material to material and thus finding the correct spin-orbit coupling structure is an important step towards advanced spintronic ap…
Bifurcations and bistability in cavity assisted photoassociation of Bose-Einstein condensed molecules
Markku Jaaskelainen, Jaeyoon Jeong, Christopher P. Search
We study the photo-association of Bose-Einstein condensed atoms into molecules using an optical cavity field. The driven cavity field introduces a new dynamical degree of freedom i…
Ballistic spin field-effect transistors: Multichannel effects
Jae-Seung Jeong, Hyun-Woo Lee
We study a ballistic spin field-effect transistor (SFET) with special attention to the issue of multi-channel effects. The conductance modulation of the SFET as a function of the R…
Optimal conversion of Bose condensed atoms into molecules via a Feshbach resonance
Jaeyoon Jeong, Chris P. Search, Ivana Djuric
In many experiments involving conversion of quantum degenerate atomic gases into molecular dimers via a Feshbach resonance, an external magnetic field is linearly swept from above…
