Yin, L., Xia, J. S., Zapf, V. S., Sullivan, N. S., Paduan-Filho, A.
In this work, we demonstrate field-induced Bose-Einstein condensation (BEC) in the organic compound NiCl$_2$-4SC(NH$_2$)$_2$ using AC susceptibility measurements down to 1 mK. The Ni $\textsl{S}$=1...
Experimental studies of the fractional quantum Hall effect in the first excited Landau level (2008)
Pan, W., Xia, J. S., Stormer, H. L., Tsui, D. C., Vicente, C., Adams, E. D., ...
We present a spectrum of experimental data on the fractional quantum Hall effect (FQHE) states in the first excited Landau level, obtained in an ultrahigh mobility two-dimensional electron system...
Disappearance of the metal-like behavior in GaAs two-dimensional holes below 30 mK (2007)
Huang, Jian, Xia, J. S., Tsui, D. C., Pfeiffer, L. N., West, K. W.
The zero-field temperature-dependence of the resistivity of two-dimensional holes are observed to exhibit two qualitatively different characteristics for a fixed carrier density for which only the...
The effect of 3He impurities on the nonclassical response to oscillation of solid 4He (2007)
Kim, E., Xia, J. S., West, J. T., Lin, X., Clark, A. C., Chan, M. H. W.
We have investigated the influence of impurities on the possible supersolid transition by systematically enriching isotopically-pure 4He (< 1 ppb of 3He) with 3He. The onset of nonclassical...
Giant viscosity enhancement in a spin-polarized Fermi liquid (2007)
Akimoto, H., Xia, J. S., Candela, D., Mullin, W. J., Adams, E. D., Sullivan, N. S.
The viscosity is measured for a Fermi liquid, a dilute $^3$He-$^4$He mixture, under extremely high magnetic field/temperature conditions ($B \leq 14.8$ T, $T \geq 1.5$ mK). The spin splitting energy...
Pan, W., Xia, J. S., Stormer, H. L., Tsui, D. C., Vicente, C. L., Adams, E. D., ...
We have observed quantization of the diagonal resistance, R_xx, at the edges of several quantum Hall states. Each quantized R_xx value is close to the difference between the two adjacent Hall...

At a very low temperature of 9mK, electrons in the 2nd Landau level of an extremely high mobility two-dimensional electron system exhibit a very complex electronic behavior. With varying filling...
New Evidence for Zero-Temperature Relaxation in a Spin-Polarized Fermi Liquid (2002)
