Abstract: Scattering coefficients can diverge at spectral singularities. In such situation, the stationary solution becomes a laser solution with outgoing waves only. We explore a parity-time $(\mathcal{PT})$-symmetric non-Hermitian two-arm Aharonov-Bohm interferometer consisting of three coupled resonators… read more here.

Abstract: A flat band is nondispersive and formed under destructive interference. Although flat bands are found in various Hermitian systems, to realize a flat band in non-Hermitian systems is an interesting task. Here, we propose a… read more here.

DOI: 10.12693/aphyspola.134.503
Abstract: We consider theoretically static and dynamic properties of vortex formation in trapped Bose–Einstein condensates in synthetic magnetic field and compare the results created by rotating frame method. As the first step, we discuss the ground… read more here.
