On quantum group symmetries of conformal field theories [PDF]
arXiv, 1991 The appearance of quantum groups in conformal field theories is traced back to the Poisson-Lie symmetries of the classical chiral theory. A geometric quantization of the classical theory deforms the Poisson-Lie symmetries to the quantum group ones. This elucidates the fundamental role of chiral symmetries that quantum groups play in conformal models ...

Advanced Functional Materials, EarlyView.A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Quantum field theory with indefinite causal structure [PDF]
arXiv, 2018 Quantum field theory (QFT) in classical spacetime has revealed interesting and puzzling aspects about gravitational systems, in particular black hole thermodynamics and its information processing. Although quantum gravitational effects may be relevant for a better understanding of these topics, a commonly accepted framework for studying QFT with ...

Advanced Functional Materials, EarlyView.This study examines the surface characteristics of AlInP (001), crucial for advanced solar cells and photoelectrochemical devices. Using theoretical modeling and experiments, it identifies how phosphorus‐rich and indium‐rich surfaces create mid‐gap states that pin the Fermi level and influence ultrafast electron dynamics.

Strings, loops and others: a critical survey of the present approaches to quantum gravity [PDF]
arXiv, 1998 I review the present theoretical attempts to understand the quantum properties of spacetime. In particular, I illustrate the main achievements and the main difficulties in: string theory, loop quantum gravity, discrete quantum gravity (Regge calculus, dynamical triangulations and simplicial models), Euclidean quantum gravity, perturbative quantum ...

Rigid Fluorescent Indacenetetraone‐Based Semiconducting Polymers via Knoevenagel Condensation
Advanced Functional Materials, EarlyView.New donor–acceptor polymers prepared by Knoevenagel condensation of indacenedithiophene‐ and indacenedifuran‐based aldehydes reveal an exceptionally rigid backbone, which is manifested in the remarkably narrow absorption and emission bands in red to near‐infrared region.

Revisiting Dynamics of Quantum Causal Structures—When Can Causal Order Evolve?
EntropyRecently, there has been substantial interest in studying the dynamics of quantum theory beyond that of states, in particular, the dynamics of channels, measurements, and higher-order transformations. Castro-Ruiz et al.
