Tight-Binding Formalism in the Context of the PythTB

In condensed matter physics, Bloch's theorem states that solutions to the Schrödinger equation in a periodic potential take the form of a plane wave modulated by a periodic function. The theorem is named after the physicist Felix Bloch, who discovered the theorem in 1929. Mathematically, they are written See more Applicability The most common example of Bloch's theorem is describing electrons in a crystal, especially in characterizing the crystal's electronic properties, such as electronic band structure See more Bloch's theorem is as follows: For electrons in a perfect crystal, there is a basis of wave functions with the following two properties: Each of these wave functions is an energy eigenstate Each of these wave functions is a Bloch state, meaning that this … See more • Bloch oscillations • Bloch wave – MoM method • Electronic band structure See more • Ashcroft, Neil; Mermin, N.

Solution of the Bloch Equations including Relaxation

WebSolution of Bloch equations with T1, T2 → ∞ [ edit] Assume that: at t = 0 the transverse nuclear magnetization Mxy (0) experiences a constant magnetic field B ( t) = (0, 0, B0 ); B0 is positive; there are no longitudinal and transverse relaxations (that is T1 and T2 → ∞). Then the Bloch equations are simplified to: , .
