Fractional Periodicity of Persistent Currents: A Signature of Broken Internal Symmetry
P. Singha Deo, P. Koskinen, M. Koskinen +1
We show from the symmetries of the many body Hamiltonian, cast into the form of the Heisenberg (spin) Hamiltonian, that the fractional periodicities of persistent currents are due…

Scattering phase shifts in quasi-one-dimension
P. Singha Deo, Swarnali Bandopadhyay, Sourin Das
Scattering of an electron in quasi-one dimensional quantum wires have many unusual features, not found in one, two or three dimensions. In this work we analyze the scattering phase…
