Isotropic-nematic transition in hard-rod fluids: relation between continuous and restricted-orientation models
Kostya Shundyak, René van Roij
We explore models of hard-rod fluids with a finite number of allowed orientations, and construct their bulk phase diagrams within Onsager's second virial theory. For a one-componen…
GBT Discovery of Two Binary Millisecond Pulsars in the Globular Cluster M30
Scott M. Ransom, Ingrid H. Stairs, Donald C. Backer +4
We report the discovery of two binary millisecond pulsars in the core-collapsed globular cluster M30 using the Green Bank Telescope (GBT) at 20 cm. PSR J2140-2310A (M30A) is an ecl…
Efficient sampling in complex materials at finite temperature: the thermodynamically-weighted activation-relaxation technique
Normand Mousseau, G. T. Barkema
We present an accelerated algorithm that samples correctly the thermodynamic ensemble in complex systems where the dynamics is controlled by activation barriers. The efficiency of…
Magnetic field decay, or just period-dependent beaming?
Joeri van Leeuwen, Frank Verbunt
Several recent papers conclude that radio-pulsar magnetic fields decay on a time-scale of 10 Myr, apparently contradicting earlier results. We have implemented the methods of these…
Free planar isotropic-nematic interfaces in binary hard-rod fluids
Kostya Shundyak, Rene van Roij
Within the Onsager theory we study free planar isotropic-nematic interfaces in binary mixtures of hard rods. For sufficiently different particle shapes the bulk phase diagrams of t…
Space-time foam in 2D and the sum over topologies
R. Loll, W. Westra
It is well-known that the sum over topologies in quantum gravity is ill-defined, due to a super-exponential growth of the number of geometries as a function of the space-time volum…
