Dependence of electromagnetically induced transparency on pressure and temperature in a quantum dot with flat cylindrical geometry

• The study is carried out in a quantum dot having quantum disk geometry.
• The study is carried out in the presence of a laser field and a magnetic field.
• It is found that electromagnetically induced transparency (EIT) occurs in the system.
• Influence of static magnetic field is analyzed.
• The combined effects of hydrostatic pressure, temperature and confinement length on EIT are also investigated.

We demonstrate an electromagnetically induced transparency in a quantum dot having disk geometry under two radiation fields. It is found that electromagnetically induced transparency occurs in the system. Analytical expressions for the complex electric susceptibility, absorption, dispersion and group index are presented. The combined effects of external factors such as magnetic field, hydrostatic pressure, temperature and confinement length on the electromagnetically induced transparency are investigated. Our results may have potential applications in optical communication and quantum information processing.
