Detailed single crystal EPR lineshape measurements for the single molecule magnets Fe8Br and Mn12-ac

S. Hill, S. Maccagnano, K. Park +3

It is shown that our multi-high-frequency (40-200 GHz) resonant cavity technique yields distortion-free high field EPR spectra for single crystal samples of the uniaxial and biaxia…

Reconstruction of Fractional Quantum Hall Edges

Xin Wan, Kun Yang, E. H. Rezayi

We study the interplay of interaction, confining potential and effects of finite temperature at the edge of a quantum Hall liquid. Our exact diagonalization calculation indicates t…

Wigner Crystals in the lowest Landau level at low filling factors

Kun Yang, F. D. M. Haldane, E. H. Rezayi

We report on results of finite-size numerical studies of partially filled lowest Landau level at low electron filling factors. We find convincing evidence suggesting that electrons…

Dipolar Excitons, Spontaneous Phase Coherence, and Superfluid-Insulator Transition in Bi-layer Quantum Hall Systems at

Kun Yang

The spontaneous interlayer phase coherent (111) state of bi-layer Quantum Hall system at filling factor may be viewed as a condensate of interlayer particle-hole pairs or exc…
