Light can hit a lead halide perovskite crystal that is anything but pristine and still end up as useful electric current. That mismatch has bothered solar researchers for more than a decade. Silicon ...

Researchers from the University of Tartu Institute of Physics have developed a novel method for enhancing the quality of ...

Abstract: This paper presents a novel wideband low-profile linear-to-circular polarizer based on high refractive-index metamaterials in the X band. The proposed design is a multilayer structure that ...

Physicists have watched a quantum fluid do something once thought almost impossible: stop moving. In experiments with ultra-thin graphene, researchers observed a superfluid—normally defined by its ...

Abstract: This communication introduces a novel Graded Index (GRIN) lens that consists of four sections made of anisotropic engineered materials. The lens is specifically designed to convert the ...

Quantum physics paints a strange picture of the world, one filled with spooky connections, unsettling uncertainties and—perhaps oddest of all—particles that spontaneously spring into being from the ...
