Abstract

We extend the concept of invariant eigen-operator to pseudo-invariant eigen-operator case through analyzing the standard Jaynes–Cummings model. We find the pseudo-invariant eigen-operator in terms of supersymmetric generators of this model, which diretly leads to the energy-level gap for Jaynes–Cummings Hamiltonian.

Pseudo-invariant Eigen-Operator Method for Solving Field-Intensity-Dependent Jaynes–Cummings Model

By using the pseudo invariant eigen-operator method we analyze the field-intensity-dependent Jaynes–Gumming (JC) model. The pseudo-invariant eigen-operator is found in terms of the supersymmetric generators. The energy-level gap of this JC Hamiltonian is derived. This approach seems concise.

``Pseudo-invariant Eigen-operator" Method for Deriving Energy-Gap of an Atom-Cavity Jaynes–Cummings Hamiltonian with Atomic Centre-of-Mass Motion

Fan Hong-Yi, Xubing Tang

Using the ``pseudo-invariant eigen-operator" method we find the energy-gap of the Jaynes–Cummings Hamiltonian model of an atom-cavity system. This model takes the atomic centre-of-mass motion into account. The supersymmetric structure is involved in the Hamiltonian of an atom-cavity system. By selecting suitable supersymmetric generators and using supersymmetric transformation the Hamiltonian is diagonalized and energy eigenvectors are obtained.

SEARCHING FOR PSEUDO-INVARIANT EIGEN-OPERATOR OF THE ∧-TYPE THREE-LEVEL JAYNES–CUMMINGS MODEL

Hong‐Chun Yuan, Hong-Yi Fan, Heng-Mei Li +1 more

We utilize pseudo-invariant eigen-operator (PIEO) method to research the three-level Jaynes–Cummings (JC) model. Our main task is to simplify the JC model and then redescribe the Hamiltonian via supersymmetric transformation generators. Another is to search for the so-called PIEO in terms of supersymmetric generators, which directly leads to the energy-level gap for the above system. We believe that this new approach may be extended to deal with more other generalized JC models.

PSEUDO-INVARIANT EIGEN-OPERATOR METHOD FOR TWO GENERALIZED JAYNES–CUMMINGS MODELS

Hong-Yi Fan, Weijun Gui, JIA-ZHANG GUI

We develop the invariant eigen-operator (IEO) theory proposed in the preceding study (Phys. Lett. A321 (2004) 75) to the pseudo-invariant eigen-operator (PIEO) method, with which we derive energy-level gap of two generalized Jaynes–Cummings models. The PIEO usually exists in some Hilbert space which is spanned by the eigenvectors of conservative quantities of the dynamic system.
