Strong Coupling Corrections to the Ginzburg-Landau Theory of Superfluid ^{3}He
H. Choi, J. P. Davis, J. Pollanen +2
In the Ginzburg-Landau theory of superfluid He, the free energy is expressed as an expansion of invariants of a complex order parameter. Strong coupling effects, which increa…
Intrinsic Impurity in the High Temperature Superconductor Bi_2Sr_2CaCu_2O
Bo Chen, Sutirtha Mukhopadhyay, W. P. Halperin +2
The {}^{17}O NMR spectra of Bi_2Sr_2CaCu_2O (Bi-2212) single crystals were measured in the temperature range from 4 K to 200 K and magnetic fields from 3 to 29 T, reported…
Two-dimensional Vortices in Superconductors
Bo Chen, W. P. Halperin, Prasenjit Guptasarma +4
Superconductors have two key characteristics. They expel magnetic field and they conduct electrical current with zero resistance. However, both properties are compromised in high m…
Helium-Three in Aerogel
W. P. Halperin, J. A. Sauls
Liquid 3He confined in silica aerogel provides us with a unique system to study the effects of quenched disorder on the properties of a strongly correlated quantum liquid. The supe…
Specific Heat of Disordered Superfluid He
H. Choi, K. Yawata, T. M. Haard +6
The specific heat of superfluid He, disordered by a silica aerogel, is found to have a sharp discontinuity marking the thermodynamic transition to superfluidity at a temperat…
Comment on "Magnetic Field Independence of the Spin Gap in YBa_2Cu_3O_{7-d}" by K. Gorny et al., Phys. Rev. Lett. 82, 177 (1999)
V. F. Mitrovi{ć}, H. N. Bachman, W. P. Halperin +2
In a recent Letter of Gorny et al. it was reported that the spin-lattice relaxation rate in YBCO_{7-d} is magnetic field independent. These authors point out that their results are…
