Interaction of a Four-Level Atom with a Deformed Quantum Field: Mathematical Model and Quantum Resources

Axioms
We introduce a framework presenting the interaction between a four-level atom (F-LA) and a field mode that begins in a coherent state within the para-Bose field (P-BF). The F-LA is considered in a cascade configuration and initially prepared in the upper

Simplified Carrier-Based SVDPWM Methods Using Reduced Common Mode Voltage Vector Redundancy for Improving Output Current Ripple in Four-Level NPC Inverter

IEEE Access
In this article, new fast and Three-level reduced common-mode voltage (RCMV) space vector Discontinuous pulse width modulation (SVDPWM) strategies are proposed to achieve high performance in four-level neutral point clamped (4L-NPC) inverters.

Localizing of a Four-Level Atom via Absorption Spectrum [PDF]

Journal of Sciences, Islamic Republic of Iran, 2006
We propose a scheme for localizing an atom in a four-level configuration inside a classical standing wave field, conditioned upon the measurement of frequency of a weak probe field.
