Article Abstract
The spectral structure of a photonic reservoir shapes radiation phenomena for embedded quantum emitters. We implement an all-optical analog to study such an effect, particularly to observe the non-Markovian radiation dynamics of an emitter coupled to two-dimensional structured reservoirs. Its dynamics is simulated by light propagating through a photonic lattice, acting as a reservoir for an adjacent waveguide that mimics a coupled quantum emitter. We study radiation dynamics in square and Lieb lattices under different coupling regimes and observe how the flat band properties of the Lieb lattice significantly enhances light-matter coupling and non-Markovianity. Our platform opens a path for the experimental exploration of single-photon quantum optical phenomena in structured reservoirs to enhance light-matter interactions.

The coupling between transition metal dichalcogenides (TMDCs) and SrTiO has recently emerged as a fertile platform for discovering interfacial phenomena, where particle interactions, lattice coupling, and dielectric screening give rise to interesting physical effects. These hybrid systems hold significant promise for two-dimensional (2D) electronics, ferroelectric state control, and metastable phase engineering. However, effective modulation of the interfacial electronic structure remains a critical challenge.

Nature uses elongated shapes and filaments to build stable structures, generate motion and allow complex geometric interactions. In this review, we examine the role of biological filaments across different length scales. From the molecular scale, where cytoskeletal filaments provide a robust but dynamic cellular scaffolding, over the scale of cellular appendages like cilia and flagella, to the scale of filamentous microorganisms like cyanobacteria, among the most successful genera on Earth, and even to the scale of elongated animals like worms and snakes, whose motility modes inspire robotic analogues.

Polymorphic two-dimensional (2D) transition metal dichalcogenides (TMDCs) exhibit diverse properties for optoelectronic applications. Here, utilizing phase-engineered MoTe as a prototypical platform, we comprehensively explored its ultrafast and nonlinear optical properties to complete the fundamental framework of phase-dependent optical phenomena in 2D TMDCs. Starting with the phase-selective synthesis of 2H- and 1T'-MoTe with tailored thicknesses, we revealed their distinct photocarrier relaxation mechanisms using intensive power-/temperature-/thickness-dependent transient absorption spectra (TAS).

Human brain organoids, generated from pluripotent stem cells, recapitulate fundamental features of human brain development, including neuronal diversity, regional architecture, and functional network activity. Integrated multimodal and transcriptomic analyses reveal a molecular repertoire of ionotropic receptors supporting action potentials, synaptic transmission, and oscillatory dynamics resembling early brain activity. This review synthesizes current knowledge on the molecular and electrophysiological determinants of neuronal maturation and network computations, from synaptic integration to large-scale dynamics.

Glycolipids are key structural and functional components of biological membranes, yet their interfacial hydration behavior remains poorly understood. Here, we use vibrational heterodyne-detected sum-frequency generation (HD-SFG) spectroscopy to probe the molecular structure of the air-water interface formed by monolayers of ohmline, a glycolipid bearing a lactose headgroup and carrying no formal charge. Upon electrolyte addition, we observe a striking reorientation of interfacial water and a reversal of the HD-SFG signal, indicative of apparent surface charging by an otherwise neutral headgroup.
