A Closed-Form Approach to Oscillatory Integrals in Level-Crossing Physics
Maseim B. Kenmoe, Anicet D. Kammogne
We present a closed-form, exact analytical solution, valid at finite times, to a class of multiple integrals with highly oscillatory kernels. Our approach leverages the intimate co…
Effect of spontaneous emission on a tanh model
A. D. Kammogne
This study examines the impact of spontaneous emission on a tanh model. The effect is characterized by introducing an imaginary term and a shift in the model, resulting in its non-…
Spontaneous emission in an exponential model
A. D. Kammogne, L. C. Fai
The phenomenon of spontaneous emission can lead to the creation of an imaginary coupling and a shift. To explore this, we utilized the renormalized first Nikitin model, revealing a…
Landau-Zener transitions in a qubit periodically driven in both longitudinal and transverse directions
A. B. Tchapda, M. B. Kenmoe, A. D. Kammogne +1
We theoretically investigate the dynamics of a spin-qubit periodically driven in both longitudinal and transverse directions by two classical fields respectively a radio-frequency…
