Ultra-broadband and compact 22 3-dB silicon adiabatic coupler based on supermode-injected adjoint shape optimization
Hongliang Chen, Guangchen Su, Xin Fu +1
The 22 3-dB couplers are one of the most widely used and important components in silicon photonics. We propose an ultra-broadband and compact 22 3-dB adiabatic coup…
Entanglement phase transitions in non-Hermitian Floquet systems
Longwen Zhou
The competition between unitary time-evolution and quantum measurements could induce phase transitions in the entanglement characteristics of quantum many-body dynamics. In this wo…
Correlation-induced phase transitions and mobility edges in an interacting non-Hermitian quasicrystal
Tian Qian, Yongjian Gu, Longwen Zhou
Non-Hermitian quasicrystal constitutes a unique class of disordered open system with PT-symmetry breaking, localization and topological triple phase transitions. In this work, we u…
Entanglement phase transitions in non-Hermitian quasicrystals
Longwen Zhou
The scaling law of entanglement entropy could undergo qualitative changes during the nonunitary evolution of a quantum many-body system. In this work, we uncover such entanglement…
Super stealth dicing of transparent solids with nanometric precision
Zhen-Ze Li, Hua Fan, Lei Wang +9
Laser cutting of semiconductor wafers and transparent dielectrics has become a dominant process in manufacturing industries, encompassing a wide range of applications from flat dis…
Transition between radial and toroidal orders in a trimer-based magnetic metasurface
Vladimir R. Tuz, Andrey B. Evlyukhin, Volodymyr I. Fesenko
The change in the arrangement of magnetic dipole moments in a magnetic metasurface, due to the influence of an external static magnetic field, is discussed. Each meta-atom of the m…
