Journal ArticleDOI
Vortices in high-temperature superconductors
TL;DR: The Ginzburg number as discussed by the authors was introduced to account for thermal and quantum fluctuations and quenched disorder in high-temperature superconductors, leading to interesting effects such as melting of the vortex lattice, the creation of new vortex-liquid phases, and the appearance of macroscopic quantum phenomena.
Journal ArticleDOI
Theory of collective flux creep
TL;DR: The nature of flux-creep phenomena in the case of collective pinning by weak disorder is discussed and the Anderson concept of flux bundle is explored and developed.
Journal ArticleDOI
From isotropic to anisotropic superconductors: A scaling approach.
Gianni Blatter,Gianni Blatter,Vadim B. Geshkenbein,Vadim B. Geshkenbein,A. I. Larkin,A. I. Larkin +5 more
TL;DR: A new scaling approach is presented which allows one to map results obtained for isotropic superconductors to anisotropic materials in a simple and direct way.
Journal ArticleDOI
Thermodynamic observation of first-order vortex-lattice melting transition in Bi2Sr2CaCu2O8
Eli Zeldov,D. Majer,Marcin Konczykowski,Vadim B. Geshkenbein,Valerii M. Vinokur,Hadas Shtrikman +5 more
TL;DR: In this article, the lattice of magnetic flux lines that can permeate a type ii superconductor, such as the high-transition-temperature copper oxide materials, was found to be first-order.
Journal ArticleDOI
Geometrical barriers in high-temperature superconductors.
Eli Zeldov,A. I. Larkin,A. I. Larkin,Vadim B. Geshkenbein,Vadim B. Geshkenbein,Marcin Konczykowski,D. Majer,Boris Khaykovich,V. M. Vinokur,Hadas Shtrikman +9 more
TL;DR: A theoretical description of vortex dynamics in thin flat samples is derived and is found to compare favorably with experimental results, finding a vortex concentration in the center of the sample and a zero-field peak in the magnetization loops.
