Spectroscopy of metal "superatom" nanoclusters and high- superconducting pairing
Avik Halder, Vitaly V. Kresin
A unique property of metal nanoclusters is the "superatom" shell structure of their delocalized electrons. The electronic shell levels are highly degenerate and therefore represent…
Nanocluster ionization energies and work function of aluminum, and their temperature dependence
Avik Halder, Vitaly V. Kresin
Ionization threshold energies of Al (n=32-95) nanoclusters are determined by laser ionization of free neutral metal clusters thermalized to several temperatures in the range fr…
A novel feature in aluminum cluster photoionization spectra and possibility of electron pairing at T>~100K
Avik Halder, Anthony Liang, Vitaly V. Kresin
A unique property of size-resolved metal nanocluster particles is their "superatom"-like electronic shell structure. The shell levels are highly degenerate, and it has been predict…
Flat Thomas-Fermi artificial atoms
Yu. N. Ovchinnikov, Avik Halder, Vitaly V. Kresin
We consider two-dimensional (2D) "artificial atoms" confined by an axially symmetric potential . Such configurations arise in circular quantum dots and other systems effectiv…
Statistical Physics Analysis of Maximum a Posteriori Estimation for Multi-channel Hidden Markov Models
Avik Halder, Ansuman Adhikary
The performance of Maximum a posteriori (MAP) estimation is studied analytically for binary symmetric multi-channel Hidden Markov processes. We reduce the estimation problem to a 1…
