Disclination states in nonreciprocal topological networks
Romain Christophe Rémy Fleury, Haoye Qin, Zhechen Zhang, Qiaolu Chen
Recently, nonreciprocal two-dimensional unitary scattering networks have gained considerable interest due to the possibility of obtaining robust edge wave propagation in their anomalous topological insulating phase. However, zero-dimensional states in such ...
2024Ultrafast control of emergent quantum matter probed by electron microscopy
Benoît Guilhem Michel Binh Truc
In the quest for controlling materials' properties, light as an external stimulus has a special place as it can create new states of matter and enable their ultrafast manipulation. In particular, spintronics, an exciting emergent field relying on the elect ...
EPFL2023Percolation and phase behavior in cellulose nanocrystal suspensions from nonlinear rheological analysis
We examine the influence of surface charge on the percolation, gel-point and phase behavior of cellulose nanocrystal (CNC) suspensions in relation to their nonlinear rheological material response. Desulfation decreases CNC surface charge density which lead ...
ELSEVIER SCI LTD2023Unconventional Flat Chern Bands and 2e Charges in Skyrmionic Moire Superlattices
The interplay of topological characteristics in real space and reciprocal space can lead to the emergence of unconventional topological phases. In this Letter, we implement a novel mechanism for generating higher-Chern flat bands on the basis of twisted bi ...
AMER CHEMICAL SOC2023Emergent non-Hermitian localization phenomena in the synthetic space of zero-dimensional bosonic systems
Phase transitions in non-Hermitian systems are at the focus of cutting edge theoretical and experimental research. On the one hand, parity-time- (PT-) and anti-PT-symmetric physics have gained ever-growing interest, due to the existence of non-Hermitian sp ...
AMER PHYSICAL SOC2023Mechanism of Reduction of Aqueous U(V)-dpaea and Solid-Phase 2 U(VI)-dpaea Complexes: The Role of Multiheme c‑Type Cytochromes
Marinella Mazzanti, Rizlan Bernier-Latmani, Karin Lederballe Meibom, Margaux Camille Andréa Molinas, Radmila Faizova
The biological reduction of soluble U(VI) complexes to form immobile U(IV) species has been proposed to remediate contaminated sites. It is well established that multiheme c-type cytochromes (MHCs) are key mediators of electron transfer to aqueous phase U( ...
2023Active Acoustic Su-Schrieffer-Heeger-Like Metamaterial
Romain Christophe Rémy Fleury, Hervé Lissek, Mathieu François Padlewski, Maxime Volery, Xinxin Guo
An acoustic dimer composed of two electronically controlled electroacoustic resonators is presented with the view of exploring one-dimensional topological phenomena. Active control allows real-time manipulation of the metamaterial’s properties, including i ...
2023Modeling and characterization of the nucleation and growth of carbon nanostructures in physical synthesis
Carbon nanostructures formed through physical synthesis come in a variety of sizes and shapes. With the end goal of rationalizing synthetic pathways of carbon nanostructures as a function of tunable parameters in the synthesis, we investigate how the initi ...
ELSEVIER2023Thermal Modelling and Experimental Validation in the Perspective of Tool Steel Laser Polishing
Eric Boillat, Alexandre Masserey, Bastian Meylan
Laser polishing (LP) is a process that allows a significant reduction of the surface roughness of a metal workpiece via re-melting a shallow layer of material. However, the practical use of LP is limited due to the difficulty of satisfying the high surface ...
MDPI2022Nonequilibrium quasistationary spin disordered state in ?-RuCl3
We photoexcite high-energy holon-doublon pairs as a way to alter the magnetic free energy landscape and resulting phase diagram of the frustrated honeycomb magnet ??-RuCl3. The pair recombination through multimagnon emission is tracked through the time evo ...
