A Phenomenological Symmetry Rule for Chemical Reactivity Under Vibrational Strong Coupling

Angewandte Chemie, EarlyView.
A general symmetry rule emerges from the study of charge transfer complexes in cavities that points to an underlying framework to the predict the outcome of chemical reactivity under vibrational strong coupling. Abstract Symmetry is known to strongly influence the course of a chemical reaction.

A note on Fibonacci matrices of even degree

International Journal of Mathematics and Mathematical Sciences, 2001
This paper presents a construction of m-by-m irreducible Fibonacci matrices for any even m. The proposed technique relies on matrix representations of algebraic number fields which are an extension of the golden section field.

Irreducible representations of $\mathbb{Z}_2^2$-graded supersymmetry algebra and their applications

SciPost Physics Proceedings, 2023
We give a brief review on recent developments of $\mathbb{Z}_2^n$-graded symmetry in physics in which hidden $\mathbb{Z}_2^n$-graded symmetries and $\mathbb{Z}_2^n$-graded extensions of known systems are discussed.

High‐Performance Phototransistor Based on a 2D Polybenzimidazole Polymer

Advanced Materials, EarlyView.
A crystalline 2D polybenzimidazole polymer (2DPBI), incorporating a porphyrin‐based π‐system linked via 1,3‐diazole units, is synthesized on the water surface over large areas. The 2DPBI thin‐film exhibits high charge carrier mobility (≈240 cm2 V−1 s−1, measured by terahertz spectroscopy), strong photoresponse, and band‐like transport, enabling ...

Quantitatively Predicting Angle‐Resolved Polarized Raman Intensity of Anisotropic Layered Materials

Advanced Materials, EarlyView.
This study develops comprehensive methodologies to predict angle‐resolved polarized Raman (ARPR) intensity profiles of anisotropic layered materials (ALMs), spanning from atomically‐thin layers to bulk limit. By considering birefringence, linear dichroism and multilayer interference, the complex refractive indexes and intrinsic Raman tensors are ...

Efficient operators for studying higher partial waves

EPJ Web of Conferences, 2018
An extended multi-hadron operator is developed to extract the spectra of irreducible representations in the finite volume. The irreducible representations of the cubic group are projected using a coordinate-space operator.

W_{1+\infty} and W(gl_N) with central charge N

, 1994
We study representations of the central extension of the Lie algebra of differential operators on the circle, the W-infinity algebra. We obtain complete and specialized character formulas for a large class of representations, which we call primitive ...

Mn3SnN‐Based Antiferromagnetic Tunnel Junction with Giant Tunneling Magnetoresistance and Multi‐States: Design and Theoretical Validation

Advanced Science, EarlyView.
A non‐collinear Mn3SnN/SrTiO3/Mn3SnN (001) AFMTJ is proposed with a theoretical TMR exceeding 1500%, enabled by optimal momentum (k)‐space matching between Mn3SnN's spin‐polarized Fermi surface (pk||${p}_{{\bm{k}}_{\mathbf{|}\mathbf{|}}}$) and the low‐decay‐rate (κk||${\kappa}_{{\bm{k}}_{\mathbf{|}\mathbf{|}}}$) of the SrTiO3 barrier.
