Orthogonality catastrophe in a composite fermion liquid
Abstract
We discuss the emergence of an orthogonality catastrophe in the response of a composite fermion liquid as the filling factor approaches 1/2m, where m=1,2,3.... A tunneling experiment is proposed in which dramatic changes in the I-V characteristic should be observable as is varied. Explicit I-V characteristics calculated within the so-called Modified Random Phase Approximation, are provided for =1/3 -> =1/2.
