Entanglement and magic transitions in an all-to-all non-Hermitian spin model
Sasanka Dowarah, Michael Kolodrubetz
The long-time state of a non-Hermitian system is determined by the eigenvalue with the largest imaginary part. In interacting many-body systems this eigenvalue usually cannot be tr…

Coherent matter wave emission from an atomtronic transistor
Sasanka Dowarah, Mengxin Du, Alan Zanders +3
The atomtronic matter-wave triple-well transistor is theoretically predicted to exhibit current gain and act as a coherent matter-wave emitter. In this work, we investigate the dyn…

Spectral statistics and energy-gap scaling in local spin Hamiltonians
Sasanka Dowarah
We investigate the spectral properties of all-to-all interacting spin Hamiltonians acting on exactly spins, whose coupling coefficients are drawn from a normal distribution wit…
