Magnetic control of an exciton–polariton condensate in a van der Waals magnet

Abstract Quasiparticle condensates are among the most striking solid-state manifestations of quantum physics. Coupling macroscopic real-space wavefunctions to additional degrees of freedom, such as the electron spin, would add valuable control knobs for quantum applications. Whil...

Deep-Subwavelength and Broadband Quarter-Wave Retardation in Ultrathin Hyperbolic MoOCl2

Abstract The miniaturization of polarization-controlling optical components is one of the central pursuits in nanophotonics. While traditional anisotropic materials require large propagation lengths to achieve the desired phase shifts, metasurfaces mitigate this size constraint b...

Stacking‐Controlled Spontaneous Polarization in Zn–In–S Nanosheets for Efficient Piezo‐Photocatalytic H 2 O 2 Production Toward Uranium Recovery

ABSTRACT Efficient uranium recovery from wastewater is vital for nuclear fuel sustainability and environmental protection. However, conventional photocatalytic and adsorption approaches suffer from sluggish charge separation, limited active sites, and poor selectivity. Piezo‐phot...
