Notes Double well levels For the double well potential, the WKB approximation can be applied separately in each well and in the barrier region between the wells. The resulting energy levels depend on the ...
Notes WKB approximation for Barrier Tunneling The WKB approximation, short for Wentzel–Kramers–Brillouin approximation, is a powerful method in quantum mechanics for approximating the solutions to the Schrödinger equation. The WKB approximation …
Notes Relativistic Lagrangian for a charged particle in electromagnetic field. The Lagrangian describes the dynamics of the system and is used in the Lagrangian formulation of classical mechanics to derive the equations of motion of the particle. The principle of ...
Notes Effective mass of an electron in solids In solid-state physics, the concept of effective mass is used to describe the behavior of electrons in a crystal lattice. The effective mass of an electron in a solid is ...
Notes Interpretation of mass neutron with fermi theory of beta decay In 1934, fermi made a successful theory of β decay based on Pauli's neutrino hypothesis. Fermi suggested that- The neutrino's rest mass affects how the spectrum is shaped. The ...
Notes Briet Wigner Resonance formula The Breit-Wigner formula, also known as the Breit-Wigner resonance formula, is a mathematical expression used to describe the probability of a resonance occurring in a particle physics experiment. It …
Notes Atomic Scattering factor The ratio of the radiation amplitude scattered by an atom's real electron distribution to the radiation amplitude scattered by a single electron localized as a point is known as the ...
Notes Strain and Strain components In materials science and solid-state physics, a crystal is a solid material whose atoms or molecules are arranged in a highly ordered, repeating pattern extending in all three spatial dimensions. ...
