To find the energy eigenvalues in the 3D Hilbert space

Click For Summary
SUMMARY

The discussion focuses on finding the energy eigenvalues of a Hamiltonian operator defined as \(\hat H=\alpha (\hat L^2_++\hat L^2_-)\) for a system with three degenerate angular momentum states where \(\ell=1\). Participants emphasize the importance of constructing the matrix representation of the operator to facilitate the calculation of eigenvalues. The conversation also highlights the need for clarity in notation, specifically the correct use of end tags in LaTeX formatting.

PREREQUISITES
  • Understanding of quantum mechanics and angular momentum operators
  • Familiarity with Hamiltonian mechanics
  • Knowledge of matrix representations of operators
  • Proficiency in LaTeX for mathematical notation
NEXT STEPS
  • Study the derivation of eigenvalues for Hamiltonians in quantum mechanics
  • Learn about the properties of angular momentum operators in quantum systems
  • Explore matrix diagonalization techniques for operator eigenvalue problems
  • Review LaTeX formatting for mathematical expressions and symbols
USEFUL FOR

Quantum physicists, graduate students in physics, and anyone involved in theoretical mechanics or quantum computing who seeks to deepen their understanding of energy eigenvalues in quantum systems.

A fictitious system having three degenerate angular momentum states with ##\ell=1## is described by the Hamiltonian \hat H=\alpha (\hat L^2_++\hat L^2_-) where ##\alpha## is some positive constant. How to find the energy eigenvalues of ##\hat H##?

How would you usually find the eigenvalues of an operator?

Also, the end tag is [/tex], not [\tex]. Or you can just use double hashes (##) for both tags instead.

    I tried to write the matrix form of the operator.

And that looked like? What did you do after that?
