Abstract Photochromic smart windows have drawn increasing attention as an approach to improve building energy efficiency and enhance indoor daylight comfort. However, existing photochromic still block sunlight from entering the room on sunny winter days, causing additional consumption for heating. Herein, a dual‐mode window is designed with decoupled photo thermal functions by combining colorless Fe‐doped WO 3 film rotation. Based this, selective heating cooling of between summer achieved...
Topological order is often quantified in terms of Chern numbers, each which classifies a topological singularity. Here, inspired by concepts from high-energy physics, we use quantum simulation based on the spin degrees freedom atomic Bose-Einstein condensates to characterize singularity present five-dimensional non-Abelian gauge theories-a Yang monopole. We quantify monopole numbers measured enclosing manifolds: Whereas well-known first number vanishes, second does not. By displacing...

Spin-orbit-coupled Bose-Einstein condensates (SOBECs) exhibit two new phases of matter, now known as the stripe and plane-wave phases. When interacting spin components a SOBEC spatially overlap, density modulations with periodicity given by spin-orbit coupling strength appear. In equilibrium, these fully overlap in miscible phase only domain wall immiscible phase. Here we probe modulation present any overlapping region optical Bragg scattering observe sudden drop shrinks. Using an atomic...
Recently, all-polymer solar cells (all-PSCs) have received increasing attention and made tremendous progress. However, the power conversion efficiency (PCE) of all-PSCs still lags behind polymer-donor-small-molecule-acceptor based organic cells, owing to excessive phase separation with poor miscibility between polymer donor acceptor. In this research, an "end-capped" ternary strategy is proposed by introducing PM6TPO as a third component fabricate highly efficient all-PSCs. The...
