Hot Superconductivity - Exciting Times
ABSTRACT :
After an introduction to superconductivity, we will discuss the possibility of hot superconductivity in real materials, with a focus on recent reports [1] of superconductivity at 400 K in Cu-Pb apatite. After describing the complex structure in a friendly fashion, I will discuss qualitatively a novel mechanism [2] which makes hot superconductivity at ambient pressures a remarkable possibility. I will also summarise recent Indian efforts (Awana, NPL) and Thapa-Pandey-Ghosh (IISc) to produce new hot superconductors. Room temperature superconductivity will make macroscopic quantum mechanics part of our day today life. With a proper use, we can make the earth greener and good for all forms of life.

Professor G. Baskaran is a Distinguished Professor at IITMadras. He is an Emeritus Professor position at The Institute of Mathematical Sciences, Chennai and he also holds a Distinguished Visiting Research Chair at the Perimeter Institute for Theoretical Physics at Waterloo, Canada. His Ph.D. (1975) in Theoretical Condensed Matter Physics was from the Indian Institute of Science at Bangalore. With a general interest in Theoretical physics, he focuses on Condensed Matter Physics. To name a few t opics, strongly correlated electronic systems, high Tc Superconductivity, fractional quantum Hall effect, Non-Fermi liquid states, Supersolid phase in He4, solid state Qubits, topological quantum computation etc. He is passionate about room temperature superconductivity and offers theoretical guidelines. He has a long time fascination for biology, in particular quantum processes in biological systems. He has received several awards and honours including the Shanti Swarup Bhatnagar Award (in 1990) and ICTP Prize (in 1983).
