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 Bathinda
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 Bathinda
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…
Drude's lesser known error of a factor of two and Lorentz's correction
Navinder Singh Bathinda
As is well known, Paul Drude put forward the very first quantitative theory of electrical conduction in metals in 1900. He could successfully account for the Wiedemann-Franz law wh…
