Rational CFTs on Riemann surfaces
Marianne Leitner, Werner Nahm
The partition function of rational conformal field theories (CFTs) on Riemann surfaces is expected to satisfy ODEs of Gauss-Manin type. We investigate the case of hyperelliptic sur…
An algebraic approach to minimal models in CFTs
Marianne Leitner
CFTs are naturally defined on Riemann surfaces. The rational ones can be solved using methods from algebraic geometry. One particular feature is the covariance of the partition fun…
CFTs on Riemann Surfaces of genus : Dependence on moduli
Marianne Leitner, Werner Nahm
The dependence of the Virasoro--point function on the moduli of the Riemann surface is investigated. We propose an algebraic geometric approach that applies to any hyperelliptic…
Boundary states and edge currents for free fermions
Marianne Leitner, Werner Nahm
We calculate the ground state current densities for 2+1 dimensional free fermion theories with local, translationally invariant boundary states. Deformations of the bulk wave funct…
Spontaneous edge currents for the Dirac equation in two space dimensions
Michael J. Gruber, Marianne Leitner
Spontaneous edge currents are known to occur in systems of two space dimensions in a strong magnetic field. The latter creates chirality and determines the direction of the current…
