DOI: 10.1063/5.0013008
Abstract: Combining thermal field sensing with microwave manipulation has always been a widely pursued topic for metamaterials for some time. However, most temperature-sensitive designs for metamaterials and metasurfaces are still limited in the single absorption manipulation.… read more here.

DOI: 10.1103/physreva.96.023618
Abstract: The wave-front aberration of Raman beams induces phase noise in atom interferometers and thus limits the performance of atom interferometers. We theoretically analyze the wave-front-aberration phase noise in weakequivalence-principle tests using dual-species atom interferometers, and… read more here.

DOI: 10.1103/physrevlett.121.063901
Abstract: Complicated multipath trajectories of waves in disordered cavities cause object localization to be very challenging with traditional ray-tracing approaches. Yet it is known that information about the object position is encoded in the Green's function.… read more here.
