The physicists working in several areas of research know quite well the name of Ettore Majorana, since it is currently associated to fundamental concepts like Majorana neutrinos in particle physics and cosmology or Majorana fermions in condensed matter physics. But, probably, very few is known about other substantial contributions of that ingenious scholar, and even less about his personal background. For non specialists, instead, the name of Ettore Majorana is usually intimately related to the… 
The disappearance of Ettore Majorana: an analytic examination
The many recent researches into the mysterious disappearance of Ettore Majorana, one of the greatest minds of theoretical physics in the twentieth century, are summarised and discussed in some
Majorana Solutions to the Two-Electron Problem
The two-electron atom is the simplest nontrivial quantum system not amenable to exact solutions. Today, its relevance in the development of quantum mechanics and its pedagogical value within the
Fundamental times, lengths and physical constants: Some unknown contributions by Ettore Majorana
We review the introduction in physics of the concepts of an elementary space length and of a fundamental time scale, analyzing some related unknown contributions by Ettore Majorana. In particular, we
This paper is dedicated to the memory of Matey Mateev , a missing friend Clifford Algebras and Spinors
Expository notes on Clifford algebras and spinors with a detailed discussion of Majorana, Weyl, and Dirac spinors. The paper is meant as a review of background material, needed, in particular, in now
Majorana and the theoretical problem of photon-electron scattering
Relevant contributions by Majorana regarding Compton scattering off free or bound electrons are considered in detail, where a (full quantum) generalization of the Kramers-Heisenberg dispersion
Majorana, Pauling and the quantum theory of the chemical bond
Nonlocal electrodynamics is a formalism developed to include nonlocal effects in the measurement process in order to account for the impossibility of instantaneous measurement of physical fields.

Teaching theoretical physics: The cases of Enrico Fermi and Ettore Majorana
We report on theoretical courses by Enrico Fermi and Ettore Majorana, which give evidence of the first appearance and further development of quantum mechanics teaching in Italy. On the basis of
The talk is quite subjective in character, and is in no way complete. It is not a chapter of history of particle physics. It is a collection of a few short stories related to neutrino physics. Two of
Majorana and the Quasi-Stationary States in Nuclear Physics
Abstract A complete theoretical model describing artificial disintegration of nuclei by bombardment with α-particles, developed by Majorana as early as 1930, is discussed in detail jointly with the
Ettore Majorana’s Course on Theoretical Physics: A Recent Discovery
We analyze in some detail the course that Ettore Majorana gave on theoretical physics at the University of Naples between January and March 1938, just prior to his mysterious disappearance. We
Comments on a Paper by Majorana Concerning Elementary Particles
An early paper (1932) by Majorana, that has received but scant attention, is reexamined in light of later developments. This pioneering paper constructs a relativistically invariant theory of
An unknown story: Majorana and the Pauli‐Weisskopf scalar electrodynamics
An account is given of an interesting but unknown theory by Majorana regarding scalar quantum electrodynamics, elaborated several years before the known Pauli‐Weisskopf theory. Theoretical
Following Weyl on Quantum Mechanics: The Contribution of Ettore Majorana
After a quick historical account of the introduction of the group-theoretical description of quantum mechanics in terms of symmetries, as proposed by Weyl, we examine some unpublished papers by
80 Years of Professor Wigner's Seminal Work "On Unitary Representations of the Inhomogeneous Lorentz Group"
It is perhaps the most fundamental principle of Quantum Mechanics that the system of states forms a linear manifold,1 in which a unitary scalar product is defined.2 The states are generally
The Theory of Electric and Magnetic Susceptibilities
THE development of a scientific theory involves the interplay of observation, reasoning, and imagination. Experimental results are co-ordinated by generalisations of ever-widening scope through those
Space-Time Approach to Non-Relativistic Quantum Mechanics
Non-relativistic quantum mechanics is formulated here in a different way. It is, however, mathematically equivalent to the familiar formulation. In quantum mechanics the probability of an event which
