Special Condensed Matter Seminar, G. Baskaran, Perimeter, "Bismuth - an Element of Surprise !"
Elemental semi metals, Bi, As, Sb, alpha-Sn and Graphehe which straddle an insulator and a metal are fascinating.
Bismuth, a member in this group has been investigated for more than a century, resulting in discovery of some well known effects in solid state physics. New phenomena have appeared in recent times.
One such surprise is discovery of superconductivity at 0.5 mK.
Focussing on a quasi one dimensional organization of half filled bands in this system, I will present a rich hidden physics including a crashed high Tc superconductivity and a normal state containing superconducting phase fluctuations.
