"Universal conductance in quantum multi-wire junctions"
 
 Slideshow (PDF)
ABSTRACT:
Using boundary conformal field theory, we relate the universal conductance tensors of quantum multi-wire junctions to static correlation functions in a finite system. We then propose a general method for determining the conductance. Applying the method to a Y-junction of interacting quantum wires, we verify a theoretical prediction for the conductance of the chiral fixed-point of the Y-junction and then calculate the thus far unknown conductance of its M fixed point with the time-independent density matrix renormalization group method.
