Force generation in small ensembles of Brownian motors

Martin Linden, Tomi Tuohimaa, Ann-Beth Jonsson +1

The motility of certain gram-negative bacteria is mediated by retraction of type IV pili surface filaments, which are essential for infectivity. The retraction is powered by a stro…

The line-of-sight towards GRB 030429 at z = 2.66: Probing the matter at stellar, galactic and intergalactic scales

P. Jakobsson, J. Hjorth, J. P. U. Fynbo +21

We report the discovery of the optical afterglow (OA) of the long-duration gamma-ray burst GRB 030429, and present a comprehensive optical/near-infrared dataset used to probe the m…

Half-Filled Lowest Landau Level on a Thin Torus

Emil J. Bergholtz, Anders Karlhede

We solve a model that describes an interacting electron gas in the half-filled lowest Landau level on a thin torus, with radius of the order of the magnetic length. The low energy…

Magnetization process of spin ice in a [111] magnetic field

S. V. Isakov, K. S. Raman, R. Moessner +1

Spin ice in a magnetic field in the [111] direction displays two magnetization plateaux, one at saturation and an intermediate one with finite entropy. We study the crossovers betw…

Topological Order in the (2+1)D Compact Lattice Superconductor

Anders Vestergren, Jack Lidmar, T. H. Hansson

We study topological aspects of a compact lattice superconductor, and show that the characteristic energy splitting, , between almost degenerate ground states, is simply related…
