Solar flares, often accompanied by coronal mass ejections and other solar phenomena, are one of the most important sources affecting space weather. It is important to investigate the forecast approach of solar flares to mitigate their destructive eff

Since the quantum concept of parity-time (PT) symmetry has been introduced into the conventional inductor–capacitor resonance, strategies based on exceptional points (EP) based strategies redefine our understanding of sensitivity limitation. This c

By exploring the extraordinary property of exceptional points (EPs) in non-Hermitian systems, we here demonstrate that losses can play a constructive role in controlling bistable states. We experimentally realize the EP in a non-Hermitian meta-molecu

We introduce here the concept of establishing parity-time (PT)-symmetry through a gauge transformation involving a shift of the mirror plane for the parity operation. The corresponding unitary transformation on the system’s constitutive matrix allo

To increase the efficiency of silicon heterojunction (SHJ) solar cells (SCs), it is paramount to enhance the utilization of sunlight by light management. In this study, the dependences of weighted reflectance and thus generation current (JG) for SHJ
