Fluctuation magnetoconductivity in YBa/sub 2/Cu/sub 3/O/sub 7/ : Gaussian, three-dimensional XY, beyond three-dimensional XY, and lowest-Landau-level scaling
(2001) [Artigo de periódico]Systematic measurements of the in-plane fluctuation magnetoconductivity in a YBa₂Cu₃O₇ single crystal are presented. Fields between 0 and 14 T were applied either parallel or perpendicular to the Cu-O atomic planes. The ... -
Pairing transition, coherence transition, and the irreversibility line in granular GdBa/sub 2/Cu/sub 3/O/sub 7-[delta]/
(2000) [Artigo de periódico]We report on electrical magnetoconductivity experiments near the superconducting transition of a granular sample of GdBa₂Cu₃O₇₋₈. The measurements were performed in magnetic fields ranging from 0 to 500 Oe applied parallel ... -
Quantum criticality of spin-1 bosons in a one-dimensional harmonic trap
(2012) [Artigo de periódico]We investigate universal thermodynamics and quantum criticality of spin-1 bosons with strongly repulsive density-density and antiferromagnetic spin-exchange interactions in a one-dimensional harmonic trap. From the equation ... -
Semilinear wave equation with time-dependent exponential speed of propagation, mass and dissipation
(2022) [Artigo de periódico]In order to prove global existence (in time) of small data energy solutions to the semilinear Cauchy problem for the wave equation with time-dependent exponential speed of propagation mass and dissipation we will derive ...
