Tunneling through two resonant levels: fixed points and conductances
Sumathi Rao, Diptiman Sen
We study point contact tunneling between two leads of a Tomonaga-Luttinger liquid through two degenerate resonant levels in parallel. This is one of the simplest cases of a quantum…

Magnetic properties of a helical spin chain with alternating isotropic and anisotropic spins: magnetization plateaus and finite entropy
V. Ravi Chandra, S. Ramasesha, Diptiman Sen
We study a model which could explain some of the unusual magnetic properties observed for the one-dimensional helical spin system Co(hfac)_2 NITPhOMe. One of the properties observe…
