We respond to a recent paper by Rindler on the " Anti–Machian " nature of the Lense–Thirring effect. We remark that his conclusion depends crucially on the particular formulation of Mach's principle used.

I study the Chaté–Manneville cellular automata rules on randomly connected lattices. The periodic and quasi–periodic macroscopic behaviours associated with these rules on finite–dimensional lattices persist on an infinite– dimensional lattice with finite connectivity and symmetric bonds. The lower critical connectivity for these models is at C = 4 and the mean–field connectivity, if finite, is ...

We present results from magnetic monopoles in SU (2) lattice gauge theory at finite temperature. The lattices are 16 3 × N t , for N t = 4, 6, 8, 12, at β = 2.5115. Quantities discussed are: the spacial string tension, Polyakov loops, and the screening of timelike and spacelike magnetic currents.

In this work, we study some general property of a strongly correlated electron system defined on a lattice. Assuming that the lattice system exhibits off-diagonal long-range order, we show rigorously that this assumption would lead to Meissner effect. This generalizes previous results of continuous case to a lattice electron system.
