Fermi surface renormalization and confinement in two coupled metallic chains
, 2007 Using a non-perturbative functional renormalization group approach involving both fermionic and bosonic fields we calculate the interaction-induced change of the Fermi surface of spinless fermions moving on two chains connected by weak interchain hopping

Advanced Science, EarlyView.. ABSTRACT Colloidal quantum dots (CQDs) based on II–V semiconductors offer attractive optical absorption and carrier transport properties for infrared optoelectronics, yet their device‐relevant electronic behavior remains poorly understood. In particular, Cd3P2 CQDs have been constrained by limited control over nanocrystal growth and carrier polarity.

Advanced Science, EarlyView.The development of polarization‐sensitive ultraviolet photodetectors is limited by poor heterojunction quality and low polarization sensitivity. This study integrates synthesized CsAg2I3 single crystals with intrinsic non‐centrosymmetry into van der Waals heterojunction devices, demonstrating pronounced pyro‐phototronic effect.

A Theory of BOT Concession Contracts [PDF]
In this paper, we discuss the choice for build-operate-and-transfer (BOT) concessions when governments and rm managers do not share the same information regarding the operation characteristics of a facility.

Rigid‐Flexible Coupling Units Enable Robust Large Birefringence
Advanced Science, EarlyView.A rigid–flexible coupling strategy, combining flexible (S3)2− linear units with rigid (VO4)3− tetrahedra, yields Sr4(VO4)2S3—a robust crystal exhibiting large birefringence (Δn = 0.52@550 nm) and remarkable thermal, air, and water stability. ABSTRACT Birefringent crystals are central to polarization control in laser technologies (e.g., wave plates and ...

Proximity Ferroelectricity in Compositionally Graded Structures
Advanced Electronic Materials, EarlyView.We perform the finite element modeling of the polarization switching in the compositionally graded AlN‐Al1‐xScxN and ZnO‐Zn1‐xMgxO structures and reveal the switching of spontaneous polarization in the whole structure in all these systems. The coercive field to switch is significantly lower than the electric breakdown field of the unswitchable AlN and ...

Large Language Model in Materials Science: Roles, Challenges, and Strategic Outlook
Advanced Intelligent Discovery, EarlyView.Large language models (LLMs) are reshaping materials science. Acting as Oracle, Surrogate, Quant, and Arbiter, they now extract knowledge, predict properties, gauge risk, and steer decisions within a traceable loop. Overcoming data heterogeneity, hallucinations, and poor interpretability demands domain‐adapted models, cross‐modal data standards, and ...

Advances in understanding the molecular mechanisms of borderline ovarian tumors
Frontiers in Molecular BiosciencesBorderline ovarian tumors (BOTs), which are a special type of epithelial tumor of the ovary, lie between benign and malignant tumors and have low malignant potential. Due to the fact that the early symptoms of these tumors are relatively subtle, they are
