Beyond Eikonal Scattering in M(atrix)-Theory
Robert Helling
We study the problem of more general kinematics for the finite N M(atrix)-Model than the simple straight line motion that has been used before. This is supposed to be related to mo…
Bound States of D(2p)-D0 Systems and Supersymmetric p-Cycles
Ralph Blumenhagen, Volker Braun, Robert Helling
We discuss some issues related to D(2p)-D0 branes with background magnetic fluxes respectively, in a T-dual picture, Dp-Dp branes at angles. In particular, we describe the nature o…
Fast Tree Search for Enumeration of a Lattice Model of Protein Folding
Henry Cejtin, Jan Edler, Allan Gottlieb +5
Using a fast tree-searching algorithm and a Pentium cluster, we enumerated all the sequences and compact conformations (structures) for a protein folding model on a cubic lattice o…
A World-Volume Perspective on the Recombination of Intersecting Branes
Johanna Erdmenger, Zachary Guralnik, Robert Helling +1
We study brane recombination for supersymmetric configurations of intersecting branes in terms of the world-volume field theory. This field theory contains an impurity, correspondi…
Why Do Proteins Look Like Proteins?
Hao Li, Robert Helling, Chao Tang +1
Protein structures in nature often exhibit a high degree of regularity (secondary structures, tertiary symmetries, etc.) absent in random compact conformations. We demonstrate in a…
Supermembranes and M(atrix) Theory
Hermann Nicolai, Robert Helling
In these lectures, we review the D=11 supermembrane and supersymmetric matrix models at an introductory level. We also discuss some more recent developments in connection with non-…
