Fast Population Leakage in Astronomical Masers: Maser Amplification and Transient Superradiance
Vahid Anari, Toktam Rashidi, Fereshteh Rajabi
We use a -type three-level Maxwell--Bloch model to test whether an inverted molecular transition in an astronomical maser source can produce maser amplification or superradianc…

Quantum coherence and the invisible Universe: Subradiance as a dark matter mechanism
Martin Houde, Fereshteh Rajabi, Lamies Sati +1
The origin of dark matter in galactic halos, one of the deepest unsolved problems in astrophysics, may find an unexpected contribution from the quantum mechanics of ordinary atomic…

A Unified Maxwell-Bloch Framework for Multi-periodic 6.7 GHz Methanol Flaring in G9.62+0.20E
T. Rashidi, V. Anari, O. Powles +4
We analyze a decade of 6.7 GHz methanol monitoring data in G9.62+0.20E, confirming the known periodicities of p1 = 241.3 +/- 2.3 d and p2 = 52.5 +/- 0.3 d, and identifying three ne…
