New Criticality of 1D Fermions
M. Lassig
One-dimensional massive quantum particles (or 1+1-dimensional random walks) with short-ranged multi-particle interactions are studied by exact renormalization group methods. With r…

Bundles of Interacting Strings in Two Dimensions
C. Hiergeist, M. Lassig, R. Lipowsky
Bundles of strings which interact via short-ranged pair potentials are studied in two dimensions. The corresponding transfer matrix problem is solved analytically for arbitrary str…

Depinning in a Random Medium
H. Kinzelbach, M. Lassig
We develop a renormalized continuum field theory for a directed polymer interacting with a random medium and a single extended defect. The renormalization group is based on the ope…
