Coherent state fock basis
WebCoherent-State Approach for Majorana Representation∗ ... As we know,a two-level pure state can be described by a point on the Bloch sphere,and its evolution is perfectly represented by the trajectory of the point on the sphere.However,it seems hard to extend this geometric interpretation to a higher dimensional quantum states,since it is ... Webwe could construct a state that consists of Fock states with numbers jniand jn+ 1i. De nition: Coherent states j iare eigenfunctions of the annihilation operator ^a, so that: a^j …

Webtion of photons. For a coherent light such as laser, the electric and magnetic field behave exactly like in the classical Maxwell theory. Laser is described in terms of a coherent state. 3 Coherent State Wave Functions Coherent state of course can be studied using the conventional wave func-tions. It takes a few tricks to workt it out, however. Webthe time-dependent Schrödinger equation (TDSE) both in imaginary and real times on the basis of a static grid of coherent states (CSs). Moreover, we consider classical dynamics for the nuclei by solving their Newtonian equations of motion. By implementing classical nuclear dynamics, we compute the electronic-state potential energy curves of H+
