Quantum kinetic theory of trapped atomic gases

H. T. C. Stoof

We present a general framework in which we can accurately describe the non-equilibrium dynamics of trapped atomic gases. This is achieved by deriving a single Fokker-Planck equatio…

Brane Actions and String Dualities

Eduardo Eyras, Yolanda Lozano

An effective action for the M9-brane is proposed. We study its relation with other branes via dualities. Among these, we find actions for branes which are not suggested by the cent…

Complexity of the Havas, Majewski, Matthews LLL Hermite Normal Form algorithm

Wilberd van der Kallen

We show that the integers in the HMM LLL HNF algorithm have bit length O(m.log(m.B)), where m is the number of rows and B is the maximum square length of a row of the input matrix.…

Exact Stationary State for an ASEP with Fully Parallel Dynamics

Jan de Gier, Bernard Nienhuis

The exact stationary state of an asymmetric exclusion process with fully parallel dynamics is obtained using the matrix product Ansatz. We give a simple derivation for the determin…

The dynamics of a low-order coupled ocean-atmosphere model

L. van Veen, F. Verhulst, T. Opsteegh

A system of five ordinary differential equations is studied which combines the Lorenz-84 model for the atmosphere and a box model for the ocean. The behaviour of this system is stu…

Anomalous couplings for D-branes and O-planes

Jose F. Morales, Claudio A. Scrucca, Marco Serone

We study anomalous Wess-Zumino couplings of D-branes and O-planes in a general background and derive them from a direct string computation by factorizing in the RR channel various…
