New high-spin structure and possible chirality in In
M. Wang, Y. Y. Wang, L. H. Zhu +20
High-spin structure of In has been investigated with the Mo(N, 5)In reaction at a beam energy of 78 MeV using the in-beam spectroscopic method…
Exact wave functions for the edge state of a disk-shaped two dimensional topological insulator
M. Pang, X. G. Wu
We report the exact wave functions for the eigen state of a disk-shaped two dimensional topological insulator. The property of the edge state whose energy lies inside the bulk gap…
Influence of bulk inversion asymmetry on the magneto-optical spectrum of a HgTe topological insulator
M. Pang, X. G. Wu
The influence of bulk inversion asymmetry in [001] and [013] grown HgTe quantum wells is investigated theoretically. The bulk inversion asymmetry leads to an anti-crossing gap betw…
Identification of a [505] isomer in the neutron-rich Os nucleus
B. S. Gao, X. H. Zhou, Y. D. Fang +13
The neutron rich nucleus Os was produced in the Os(Li,Li)Os reaction. An isomeric state based on the [505] nilsson orbital was identified…
Resonant Subband Landau Level Coupling in Symmetric Quantum Well
L. -C. Tung, X. -G. Wu, L. N. Pfeiffer +2
Subband structure and depolarization shifts in an ultra-high mobility GaAs/Al_{0.24}Ga_{0.76}As quantum well are studied using magneto-infrared spectroscopy via resonant subband La…
Excitons of Composite Fermions
R. K. Kamilla, X. G. Wu, J. K. Jain
The low-energy excitations of filled Landau levels (LL's) of electrons involve promotion of a single electron from the topmost filled LL to the lowest empty LL. These are called ex…
Skyrmions in the Fractional Quantum Hall Effect
R. K. Kamilla, X. G. Wu, J. K. Jain
It is verified that, at small Zeeman energies, the charged excitations in the vicinity of 1/3 filled Landau level are skyrmions of composite fermions, analogous to the skyrmions of…
Composite fermion theory of collective excitations in fractional quantum Hall effect
R. K. Kamilla, X. G. Wu, J. K. Jain
The low energy neutral excitations of incompressible fractional quantum Hall states are called collective modes or magnetic excitons. This work develops techniques for computing th…
Skyrmions in Higher Landau Levels
X. -G. Wu, S. L. Sondhi
We calculate the energies of quasiparticles with large numbers of reversed spins (``skyrmions'') for odd integer filling factors 2k+1, k is greater than or equals 1. We find, in co…
Excitation Spectrum and Collective Modes of Composite Fermions
X. G. Wu, J. K. Jain
According to the composite fermion theory, the interacting electron system at filling factor is equivalent to the non-interacting composite fermion system at , w…
Hund's Rule for Composite Fermions
J. K. Jain, X. G. Wu
We consider the ``fractional quantum Hall atom" in the vanishing Zeeman energy limit, and investigate the validity of Hund's maximum-spin rule for interacting electrons in various…
The Variance of QSO Counts in Cells
P. Andreani, S. Cristiani, F. Lucchin +2
{}From three quasar samples with a total of 1038 objects in the redshift range we measure the variance of counts in cells of volume . By a maximum likelihood…
Half-Integral Spin-Singlet Quantum Hall Effect
L. Belkhir, X. G. Wu, J. K. Jain
We provide numerical evidence that the ground state of a short range interaction model at is incompressible and spin-singlet for a wide range of repulsive interactions. Fur…
