A Dislocation Perspective on Strength and Toughness in Ceramics

open access: yesAdvanced Engineering Materials, EarlyView.
Dislocations in ceramics enjoy a long but yet under‐appreciated history. The three research waves for dislocations in ceramics highlight the topic evolution over the last 90 years. This review focuses on the impact of dislocation on strength and toughness in ceramics.

Quantum Product and Parabolic Orbits in Homogeneous Spaces [PDF]

open access: yes, 2014
Chaput, Manivel, and Perrin proved in [3] a formula describing the quantum product by Schubert classes associated to cominuscule weights in a rational projective homogeneous space X. In the case where X has Picard rank one, we relate this formula to the

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

open access: yesAdvanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Quantum computing thanks to Bianchi groups

open access: yesEPJ Web of Conferences, 2019
It has been shown that the concept of a magic state (in universal quantum computing: uqc) and that of a minimal informationally complete positive operator valued measure: MIC-POVMs (in quantum measurements) are in good agreement when such a magic state ...

Semidual Kitaev lattice model and tensor network representation

open access: yesJournal of High Energy Physics, 2021
Kitaev’s lattice models are usually defined as representations of the Drinfeld quantum double D(H) = H ⋈ H *op, as an example of a double cross product quantum group.

Ferroelectricity in Antiferromagnetic Wurtzite Nitrides

open access: yesAdvanced Functional Materials, EarlyView.
We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and

QCD multiplet bases with arbitrary parton ordering

open access: yesJournal of High Energy Physics, 2018
We develop an algorithm for recursively constructing orthogonal multiplet bases for the color space of QCD, for any order of partons and any N c . This recipe is then applied for explicitly constructing some of these bases.

Polarizable Vanadium Dipoles Promote Water Dissociation on Vanadium‐Based Metal Organic Framework

open access: yesAdvanced Functional Materials, EarlyView.
The polarization of unpaired V 3d electrons weakens the H─O bond to improve water dissociation by the dual Vδ+:O─H and Pλ−:H─O coupling hydrogen bonds formation and relaxation. P@V‐MOF electrocatalyst shows low overpotentials (94 mV in acid, 178 mV in neutral, and 77 mV in alkaline solutions) with excellent stability for effective overall water ...

A note on quantum subgroups of free quantum groups

open access: yesComptes Rendus. Mathématique
In this short note, quantum subgroups in finite free products of the Pontryagin duals of free unitary quantum groups are classified. They correspond to pairs of a subgroup $\Gamma $ and a subset $S$ of the free group $\mathbb{F}_n$ such that $S$ is ...

Quantum D = 3 Euclidean and Poincaré symmetries from contraction limits

open access: yesJournal of High Energy Physics, 2020
Following the recently obtained complete classification of quantum-deformed o $$ \mathfrak{o} $$ (4), o $$ \mathfrak{o} $$ (1, 3) and o $$ \mathfrak{o} $$ (2) algebras, characterized by classical r-matrices, we study their inhomogeneous D = 3 quantum IW ...
