Phase space crystals

Phase space crystal is the state of a physical system that displays discrete symmetry in phase space instead of real space. For a single-particle system, the phase space crystal state refers to the eigenstate of the Hamiltonian for a closed quantum system or the eigenoperator of the Liouvillian for an open quantum system. For a many-body system, phase space crystal is the solid-like crystalline state in phase space. The general framework of phase space crystals is to extend the study of solid state physics and condensed matter physics into phase space of dynamical systems. While real space has Euclidean geometry, phase space is embedded with classical symplectic geometry or quantum noncommutative geometry. (Wikipedia).

Solid State Physics in a Nutshell: Topic 5-1: Introduction to Phonons

We begin today with a one dimensional crystal and we treat the bonds between the atoms as springs. We then develop an expression for the force acting on one particular atom. Using a plane wave approximation for the displacement we then develop an equation relating the wave vector and the f

Crystalline vs Amorphous materials

Materials are either crystalline or amorphous. They contain long-range periodic order or they do not. This leads to very different properties! Crystalline materials can be either polycrystalline or single crystal in nature. we can see evidence of single crystals in faceting of crystal face
