Bosonization of current-current interactions

Bosonization and Current Algebra of Spinning Strings

We write down a general geometric action principle for spinning strings in d-dimensional Minkowski space, which is formulated without the use of Grassmann coordinates. Instead, it is constructed in terms of the pull-back of a left invariant Maurer-Cartan form on the ddimensional Poincaré group to the world sheet. The system contains some interesting special cases. Among them are the Nambu strin...

Current Algebra and Bosonization in Three Dimensions

We consider the fermion-boson mapping in three dimensional space-time, in the Abelian case, from the current algebra point of view. We show that in a path-integral framework one can derive a general bosonization recipe leading, in the bosonic language, to the correct equal-time current commutators of the original free fermionic theory. Also at Universit e de Savoie and at Institut Universitaire...

We discuss a generalization of the conventional bosonization procedure to the case of current-current interactions which get their natural representation in terms of current instead of fermion number density operators. A consistent bosonization procedure requires a geometrical quantization of the hamiltonian action of W ∞ on its coadjoint orbits. An integrable example of a nontrivial realizatio...
