1/f Noise and Long Configuration Memory in Bak-Tang-Wiesenfeld Models on Narrow Stripes
Sergei Maslov, Chao Tang, Yi-Cheng Zhang
We report our findings of an 1/f power spectrum for the total amount of sand in directed and undirected Bak-Tang-Wiesenfeld models confined on narrow stripes and driven locally. Th…
Low Energy Excitations and Phase Transitions in the Frustrated Two-Dimensional XY Model
Colin Denniston, Chao Tang
We study the critical properties of the two-dimensional (2D) XY model in a transverse magnetic field with filling factors f=1/3 and 2/5. To obtain a comparison with recent experime…
Commensurability in One Dimension and the Josephson Junction Ladder
Colin Denniston, Chao Tang
We study a Josephson junction ladder in a magnetic field in the absence of charging effects via a transfer matrix formalism. The eigenvalues of the transfer matrix are found numeri…
Incommensurability in the Frustrated Two-Dimensional XY Model
Colin Denniston, Chao Tang
To examine the properties of the frustrated XY model at an incommensurate field we have examined a sequence of magnetic filling factors f which approach the irrational value of one…
Domain Walls and Phase Transitions in the Frustrated Two-Dimensional XY Model
Colin Denniston, Chao Tang
We study and compare the critical properties of the two-dimensional (2D) XY model in a transverse magnetic field with magnetic filling factors f=1/3 and f=2/5. In addition to the s…
