Goldfishing by gauge theory
F. Calogero, E. Langmann
A new solvable many-body problem of goldfish type is identified and used to revisit the connection among two different approaches to solvable dynamical systems. An isochronous vari…
Exact solution of a 1D many-body system with momentum dependent interactions
Harald Grosse, Edwin Langmann, Cornelius Paufler
We discuss a 1D many-body model of distinguishable particles with local, momentum dependent two-body interactions. We show that the restriction of this model to fermions correspond…
Exact Solution of Noncommutative Field Theory in Background Magnetic Fields
E. Langmann, R. J. Szabo, K. Zarembo
We obtain the exact non-perturbative solution of a scalar field theory defined on a space with noncommuting position and momentum coordinates. The model describes non-locally inter…
Interacting fermions on noncommutative spaces: Exactly solvable quantum field theories in 2n+1 dimensions
Edwin Langmann
I present a novel class of exactly solvable quantum field theories. They describe non-relativistic fermions on even dimensional flat space, coupled to a constant external magnetic…
Anomalies and Schwinger terms in NCG field theory models
E. Langmann, J. Mickelsson, S. Rydh
We study the quantization of chiral fermions coupled to generalized Dirac operators arising in NCG Yang-Mills theory. The cocycles describing chiral symmetry breaking are calculate…
The Luttinger-Schwinger Model
H. Grosse, E. Langmann, E. Raschhofer
We study the Luttinger-Schwinger model, i.e. the (1+1) dimensional model of massless Dirac fermions with a non-local 4-point interaction coupled to a U(1)-gauge field. The complete…
