Persistent currents with long-range hopping in 1D single-isolated-diffusive rings
Santanu K. Maiti, J. Chowdhury, S. N. Karmakar
We show from exact calculations that a simple tight-binding Hamiltonian with diagonal disorder and long-range hopping integrals, falling off as a power of the inter-site separa…

On the role of electron correlation and disorder on persistent currents in isolated one-dimensional rings
Santanu K. Maiti, J. Chowdhury, S. N. Karmakar
To understand the role of electron correlation and disorder on persistent currents in isolated 1D rings threaded by magnetic flux , we study the behavior of persistent currents…

Strange behavior of persistent currents in small Hubbard rings
Santanu K. Maiti, J. Chowdhury, S. N. Karmakar
We show exactly that small Hubbard rings exhibit unusual kink-like structures giving anomalous oscillations in persistent current. Singular behavior of persistent current disappear…
