Polarizability of a Wigner crystal
Navinder Singh Bathinda
We present a calculation of the imaginary part of the polarizability of a Wigner crystal using the Fluctuation-Dissipation theorem. The oscillations of the localized electrons abou…
One Rudolf Peierls' surprise: the quantum-to-classical transition in the context of solid-state physics
Navinder Singh Bathinda
In solid state physics, it is an unsaid (tacit) assumption that the Bloch theorem is applicable to a crystal lattice even if it is of the macroscopic dimensions, provided periodici…
V. J. Emery and P. W. Anderson's views and related issues regarding the basics of cuprates: a re-look
Navinder Singh
In 1991, V. J. Emery in his important review article entitled "Some aspects of the theory of high temperature superconductors"\cite{emery1} argued against the Zhang-Rice reduction…
Hot (non-equilibrium) electron relaxation: A review of the ultra-fast phenomena in metals and superconductors (PART I)
Navinder Singh
The famous Two-Temperature Model (TTM) used extensively in the investigations of energy relaxation in photo-excited systems originated in the seminal work of M. I. Kaganov, I. M. L…
