Dissipation, topology, and quantum phase transition in a one-dimensional Joesphson junction array
Pallab Goswami, Sudip Chakravarty
We study the phase diagram and quantum critical properties of a resistively shunted Josephson junction array in one dimension from a strong coupling analysis. After mapping the dis…

Photoemission From A Two Electron Quantum Dot
Pallab Goswami, Subinoy Das, J. K. Bhattacharjee
We consider photoemission from a two-electron quantum dot and find analytic expression for the cross-section. We show that the emission cross-section from the ground state as a fun…

Two Electron Quantum Dot - A Variational Treatment For The Ground State
Subinoy Das, Pallab Goswami, J. K. Bhattacharjee
A variational treatment for a two-electron quantum dot (the artificial helium atom) is proposed which leads to exact answer for the ground state energy. Depending on the magnetic f…
