# The Variational Methods of Quantum Systems in Holomorphic Representation

@inproceedings{Almasri2021TheVM, title={The Variational Methods of Quantum Systems in Holomorphic Representation}, author={Mohammad Almasri and Mohamed Ridza Wahiddin}, year={2021} }

We show that variational method for harmonic oscillator in Bargmann representation breaks down since we always end up with one of the exact eigenvalues of Hamiltonian using any normalized monomials in the complex plane. Using the holomorphic representation of pure spin systems , we also encounter the same result found earlier for harmonic oscillators in Bargmann representation. We conclude that the exact energy eigenvalues of these systems are unavoidable starting from any normalized monomials…

The thermal coherent states considered previously by the present authors represent an alternative mixed-state generalization of the usual pure-state coherent states and are shown to provide a "random" (or "thermal" or "noisy") basis on a quantum-mechanical Hilbert space scrH.
