Vor 3 Tagen · Quantum mechanics is the study of the dynamics of particles at its most fundamental level. The state of a particle, such as its position or momentum, is described by a statistical distribution ...
Vor 4 Tagen · Simplified quantum-mechanical description. The full quantum-mechanical treatment of bremsstrahlung is very involved. The "vacuum case" of the interaction of one electron, one ion, and one photon, using the pure Coulomb potential, has an exact solution that was probably first published by A. Sommerfeld in 1931.
Vor 6 Tagen · 1. 개요 [편집] 양자역학 ( 量 子 力 學, quantum mechanics), 혹은 양자물리학 (量子物理學, quantum physics)은 원자 와 이를 이루는 아원자 입자 등 미시세계와, 그러한 계에서 일어나는 현상을 탐구하는 현대물리학 의 한 분야이다. [1] 주로 미시 세계에 활용되고 있지만 ...
Vor 3 Tagen · Planck, Schrödinger, and others introduced quantum mechanics, a probabilistic notion of particles and interactions that allowed an accurate description of atomic and subatomic scales. Later, quantum field theory unified quantum mechanics and special relativity. General relativity allowed for a dynamical, curved spacetime, with which highly ...
Vor 2 Tagen · Special relativity can be combined with quantum mechanics to form relativistic quantum mechanics and quantum electrodynamics. How general relativity and quantum mechanics can be unified is one of the unsolved problems in physics ; quantum gravity and a " theory of everything ", which require a unification including general relativity too, are active and ongoing areas in theoretical research.
Vor 5 Tagen · Von Neumann established a rigorous mathematical framework for quantum mechanics with his work Mathematische Grundlagen der Quantenmechanik. He provided in this work a theory of measurement, where the usual notion of wave function collapse is described as an irreversible process (the so-called von Neumann or projective measurement ).
Vor 4 Tagen · Oppenheimer published more than a dozen papers while in Europe, including many important contributions to the new field of quantum mechanics. He and Born published a famous paper on the Born–Oppenheimer approximation , which separates nuclear motion from electronic motion in the mathematical treatment of molecules, allowing nuclear motion to be neglected to simplify calculations.
