Abstract

For the first time, we introduce a fully quantum mechanical Hamiltonian for a semi-infinite chain model of atoms. We then derive the vibration modes of this model by virtue of the "invariant eigen-operator" method in two different cases, which is concise and revealing.

Hong-Yi Fan, Hao Wu

For diatomic chain-lattice we introduce a fully quantum-mechanical Hamiltonian operator and then search for its eigen-operator, in this way the acoustic modes and optical modes are easily obtained. This approach sharply differs from the traditional classical treatment and demonstrates the directness, simplicity and efficiency of the invariant eigen-operator method.

In this paper, we apply the method of "invariant eigen-operator" to study the Hamiltonian of several different qubit-environment models. We find the invari-ant eigen-operator in terms of these models, which directly leads to the ener-gy-level gap for total system.

The Hamiltonian energylevel gap of the sodium D lines and the ordinary Zeeman effect can be obtained with convenience and directness by the invariant eigen-operator method. Applying this method,we mostly deal with the quantum operators,and do not have to refer the quantum states or wave functuion.

Fan Hong-Yi, Hao Wu

Based on the coupled harmonic oscillator model, which is born of Heisenberg ferromagnetic spin chain with nearest-neighbor interactions, we adopt the invariant eigen-operator method to derive its energy level, which provides an alternate approach to dealing with the dynamics of spin chain.
