Interaction-Induced Strong Localization in Quantum Dots
A. D. Guclu, A. Ghosal, C. J. Umrigar +1
We argue that Coulomb blockade phenomena are a useful probe of the cross-over to strong correlation in quantum dots. Through calculations at low density using variational and diffu…

Incipient Wigner Localization in Circular Quantum Dots
Amit Ghosal, A. D. Guclu, C. J. Umrigar +2
We study the development of electron-electron correlations in circular quantum dots as the density is decreased. We consider a wide range of both electron number, N<=20, and electr…

Correlation Induced Inhomogeneity in Circular Quantum Dots
Amit Ghosal, A. D. Guclu, C. J. Umrigar +2
Properties of the "electron gas" - in which conduction electrons interact by means of Coulomb forces but ionic potentials are neglected - change dramatically depending on the balan…
