  1. Derivation of momentum operator / origin of -ih d/dx

    Aug 13, 2011 · Derivation of momentum operator / origin of -ih d/dx Juqon Aug 13, 2011 Derivation Momentum Operator Origin Aug 13, 2011 #1 Juqon 31 0

  2. Is the Momentum Operator Hermitian in Quantum Mechanics?

    Mar 8, 2014 · A Hermitian operator A is defined by A=A (dagger) which is the transpose and complex conjugate of A. In 1-D the momentum operator is -i (h bar)d/dx. How can this be Hermitian as the …

  3. What is the Correct Value of the Square of a Momentum Operator ...

    Aug 25, 2012 · know I'm missing something obvious. for a momentum operator p = -iħ d/dx if I square the -iħ part I get (+1)ħ2 but I believe the correct value (as in the kinetic energy of the Hamiltonian) is …

  4. Heisenberg uncertainty principle and the canonical momentum …

    Dec 10, 2024 · The momentum operator, defined as , is applicable in free space but requires modification in the presence of a vector potential, leading to the canonical momentum expression . …

  5. How to "derive" momentum operator in position basis using STE?

    Apr 27, 2024 · In Introduction to Quantum Mechanics by Griffiths and Schroeter, the IMO motivates the form of momentum operator in position basis in a very nice manner. However, the problem is that …

  6. What is the Time Evolution of the Angular Momentum Operator?

    Jan 30, 2014 · To have an operator inherit the time dependence we simply make use of the unitary representation of time translations. Then our angular momentum operator would inherit time …

  7. How Does Position Interact with Spin Angular Momentum in Quantum ...

    Nov 30, 2023 · The spin angular momentum operator commutes with both position and momentum (i.e., its commutator with those operators vanishes), since it operates on a different part of the Hilbert …

  8. No r dependence in L operator? • Physics Forums

    Feb 20, 2017 · In classical mechanics, angular momentum, L = r x p, depends of r. For a given momentum p, the bigger r is, the bigger is the angular momentum. Event in spherical coordinates, r …

  9. Understanding the Momentum Operator in Quantum Mechanics

    Mar 26, 2005 · The discussion centers on the origin and understanding of the momentum operator in quantum mechanics, specifically the expression P = -ih/ (2π) * d/dx. Participants highlight the …
