The recent detection of a Fast Radio Burst (FRB) from a Galactic magnetar secured the fact that neutron stars (NSs) with super-strong magnetic fields are capable of producing these extremely bright coherent radio bursts. One of the leading…

In this Letter we show that the strong coupling between a disordered set of molecular emitters and surface plasmons leads to the formation of spatially coherent hybrid states extended on acroscopic distances. Young type interferometric…

It has recently been proposed that radio emission from magnetars can be evaluated using a "fundamental plane" in parameter space between pulsar voltage gap and ratio of X-ray luminosity Lx to rotational energy loss rate Edot. In particular,…
