Dynamic scaling theory of the Kosterlitz-Thouless-Berezinskii transition: ubiquitous finite size effects
Louis Colonna-Romano, Stephen W. Pierson, Mark Friesen
A numerical study of the neutral two-dimensional (2D) lattice Coulomb gas is performed to examine dynamic scaling, finite size effects, and the dynamic critical exponent of the…
Flux Lattice Melting and the onset of H_c2 fluctuations
Stephen W. Pierson, Oriol T. Valls
The flux lattice melting temperature in optimally doped YBCO has been shown to be very close to that of the onset of fluctuations around H_{c2}(T). Here, we present a theoretical a…
Dynamic scaling of I-V data for the neutral 2D Coulomb gas
Stephen W. Pierson, Mark Friesen
The value of the dynamic critical exponent z has been studied for experimental two-dimensional superconducting and Josephson Junction array systems in zero magnetic field via the F…
Dynamic scaling for 2D superconductors, Josephson junction arrays and superfluids
S. W. Pierson, M. Friesen, S. M. Ammirata +2
The value of the dynamic critical exponent is studied for two-dimensional superconducting, superfluid, and Josephson Junction array systems in zero magnetic field via the Fishe…
Renormalization Group Study of the Intrinsic Finite Size Effect in 2D Superconductors
Stephen W. Pierson, Oriol T. Valls
Vortices in a thin-film superconductor interact logarithmically out to a distance on the order of the two-dimensional (2D) magnetic penetration depth , at which point the…
Dynamic Scaling at the Zero-field 2D Superconducting Transition
S. M. Ammirata, Mark Friesen, Stephen W. Pierson +4
Zero-field current-voltage (I-V) characteristics of a thin ("two-dimensional") crystal are reported and analyzed in two ways. The "conventional" approach yi…
Flux Lattice Melting and Lowest Landau Level Fluctuations
Stephen W. Pierson, Oriol T. Valls
We discuss the influence of lowest Landau level (LLL) fluctuations near H_{c2}(T) on flux lattice melting in YBaCuO (YBCO). We show that the specific heat step of t…
A Review of the Real Space Renormalization Group Analysis of the Two- Dimensional Coulomb Gas, the Kosterlitz-Thouless-Berezinski Transition, and Extensions to a Layered Vortex Gas
Stephen W. Pierson
Fundamental properties of the Kosterlitz-Thouless-Berezinskii (KTB) transition which occurs in systems in the universality class of the two-dimensional X-Y model are reviewed here…
3D Lowest Landau Level Theory Applied to YBCO Magnetization and Specific Heat Data: Implications for the Critical Behavior in the H-T Plane
Stephen W. Pierson, Oriol T. Valls, Zlatko Tesanovic +1
We study the applicability of magnetization and specific heat equations derived from a lowest-Landau-level (LLL) calculation, to the high-temperature superconducting (HTSC) materia…
The Current-Temperature Phase Diagram of Layered Superconductors
Stephen W. Pierson
The behavior of clean layered superconductors in the presence of a finite electric current and in zero-magnetic field behavior is addressed. The structure of the current temperatur…
