Dipolar BEC
Dipolar BEC
Overview:
Overview:
Dipolar BECs are ultracold quantum gases made of atoms or molecules that possess a permanent magnetic or electric dipole moment. Unlike conventional BECs with only short-range contact interactions, dipolar BECs exhibit long-range and anisotropic dipole–dipole interactions, leading to rich and exotic quantum behavior.

Overview:
Polariton condensates are quantum fluids formed by polaritons- bosonic quasiparticles that are coherent mixtures of light (photons) with excitons (electron-hole pairs) in a solid-state system, typically inside an optical cavity.

This hybridization leads to dressed photons that acquire:
- Light effective mass: unlike atomic BECs, Condensation can occur at relatively high temperatures, even at room temperature.
- Strong interactions inherited from the excitonic component→ enable collective many-body behavior.
Polariton condensates behave like bosonic quantum fluids and exhibit macroscopic quantum phenomena, such as Bose-Einstein condensation, at much higher temperatures than atomic gases.
