Umklapp Processes for Electrons and Their Renormalisation Group Flow
Deepak Kumar, R. Rajaraman
We study Umklapp couplings and their renormalisation group flow for electrons in a two dimensional lattice. It is shown that the effective low energy Hamiltonian involves not only…
Role of Defects in Self-Organized Criticality: A Directed Coupled Map Lattice Model
Bosiljka Tadic, Ramakrishna Ramaswamy
We study a directed coupled map lattice model in two dimensions, with two degrees of freedom associated with each lattice site. The two freedoms are coupled at a fraction of la…
A Field Theory for the Read Operator
R. Rajaraman, S. L. Sondhi
We introduce a new field theory for studying quantum Hall systems. The quantum field is a modified version of the bosonic operator introduced by Read. In contrast to Read's origina…
