Magnetic Fields

In comparison to the vapour gas-compression refrigeration, magnetic heat-pumping near room-temperature is regarded to be an alternative technology due to its high energy efficiency and environmentally friendly solid-state cooling materials. The magnetic heat pump technology utilizes the magnetic field induced temperature change, which is based on the magnetocaloric effect (MCE).

In this work, we proposed a simple model for control of subluminal and superluminal light propagation via an external magnetic field in a lambda configuration degenerate two-level atomic medium. We show that the absorption-dispersion properties and group index under the influence of the strength of coupling laser and external magnetic fields are controlled.
