Majorana's stellar representation for the local polarization of harmonic electromagnetic and gravitational waves
Patrick Bruno
The local polarization of electromagnetic (EMW) and gravitational waves (GW) is discussed from an operational point of view, in which all the relevant mathematical framework is con…
Jacques Friedel and the physics of metals and alloys
Jacques Villain, Mireille Lavagna, Patrick Bruno
This is an introduction to the theoretical physics of metals for students and physicists from other specialities. Certain simple consequences of the Fermi statistics in pure metals…
Maxwell-Sylvester Multipoles and the Geometric Theory of Irreducible Tensor Operators of Quantum Spin Systems
Patrick Bruno
A geometric theory of the irreducible tensor operators of quantum spin systems. It is based upon the Maxwell-Sylvester geometric representation of the multipolar electrostatic pote…
Impossibility of Spontaneously Rotating Time-Crystals: A No-Go Theorem
Patrick Bruno
I present arguments indicating the impossibility of spontaneously rotating quantum timecrystals, as recently proposed by Frank Wilczek [arXiv:1202.2539]. In particular, I prove a N…
