Role of Resonant k\mathbf{k}-Points in the Transient Optical Response of Pumped Germanium

This study reveals that in pumped germanium, the transient optical response is dominated by resonant crystal momenta rather than the total residual excitation population, demonstrating that virtual pump-induced contributions from resonant regions are crucial for determining the material's optical weight.

Spin injection of exciton-polaritons with halide perovskites at room temperature

This study demonstrates room-temperature spin injection and preservation in exciton-polaritons within a monolithic Tamm-plasmon microcavity embedding 2D halide perovskites, where rapid polariton decay outcompetes spin relaxation mechanisms to enable potential applications in chiral lasers and switches.

Single photon emitters in hBN: Limitations of atomic resolution imaging and potential sources of error

This study demonstrates that identifying single-photon emitters in hexagonal boron nitride using atomic-resolution ADF-STEM is fundamentally limited by sample thickness (beyond ~17 layers) and susceptible to misidentification due to residual threefold astigmatism, rendering the technique unreliable for the thicker flakes typically used in photonic research.

Dynamics of Long-lived Carriers in Molybdenum Carbide Nanosheets

This study reveals that Molybdenum Carbide (MoC) nanosheets exhibit significantly longer carrier lifetimes than other transition metal carbides due to restricted phonon decay pathways caused by the large mass difference between Mo and C atoms, offering a promising strategy for enhancing photothermal and photovoltaic device performance through efficient hot carrier utilization.
