Light Absorption in Quantum Narrowing in a Longitudinal Magnetic Field

Key Points

• The research aims to explore how light absorption in quantum narrowings is affected by a longitudinal magnetic field.
• Examined the optical properties of micro-narrowing under varying magnetic field strengths.
• Utilized a soft wall potential model for the confinement of micro-narrowings.
• Analyzed the transition from micro-narrowing to quantum wire characteristics.
• The light absorption coefficient varies significantly with the strength of the external magnetic field.
• Findings indicate a clear limiting transition from micro-narrowing to quantum wire as field strength increases.
