Observation of a singular Weyl point surrounded by charged nodal walls in PtGa

Oleg Yazyev, Jan Hugo Dil, Quansheng Wu, Shengnan Zhang

Constrained by the Nielsen-Ninomiya no-go theorem, in all so-far experimentally determined Weyl semimetals (WSMs) the Weyl points (WPs) always appear in pairs in the momentum space with no exception. As a consequence, Fermi arcs occur on surfaces which con ...

Asymmetric azide-alkyne Huisgen cycloaddition on chiral metal surfaces

Harald Brune, Roland Hany, Roland Widmer, Michael Bauer, Samuel Thomas Stolz

Achieving fundamental understanding of enantioselective heterogeneous synthesis is marred by the permanent presence of multitudinous arrangements of catalytically active sites in real catalysts. In this study, we address this issue by using structurally co ...

Arrested phase separation in chiral fluids of colloidal spinners

Ignacio Pagonabarraga Mora

We investigate phase separation in a chiral fluid, made of spinning ferromagnetic colloids that interact both via hydrodynamic and dipolar forces and collectively organize into separated circulating clusters. We show that, at high spinning frequency, hydro ...

Dielectric Metasurfaces Enabling Advanced Optical Biosensors

Hatice Altug, Aleksandrs Leitis, Ming-Lun Tseng

Dielectric metasurfaces have emerged as a powerful platform for novel optical biosensors. Due to their low optical loss and strong light-matter interaction, they demonstrate several exotic optical properties, including sharp resonances, strong nearfield en ...

Visible-Light-Driven Catalytic Deracemization of Secondary Alcohols

Xile Hu, Zhikun Zhang

Deracemization of racemic chiral compounds is an attractive approach in asymmetric synthesis, but its development has been hindered by energetic and kinetic challenges. Here we describe a catalytic deracemization method for secondary benzylic alcohols whic ...

Chiral Alkyl Amine Synthesis via Catalytic Enantioselective Hydroalkylation of Enecarbamates

Xile Hu, Srikrishna Bera, Deyun Qian

Chiral alkyl amines are omnipresent as bioactive molecules and synthetic intermediates. The catalytic and enantioselective synthesis of alkyl amines from readily accessible precursors is challenging. Here we develop a nickel-catalyzed hydroalkylation metho ...

Near-Enantiopure Trimerization of 9-Ethynylphenanthrene on a Chiral Metal Surface

Harald Brune, Roland Widmer, Aliaksandr Yakutovich, Jan Prinz, Samuel Thomas Stolz

Enantioselectivity in heterogeneous catalysis strongly depends on the chirality transfer between catalyst surface and all reactants, intermediates, and the product along the reaction pathway. Herein we report the first enantioselective on-surface synthesis ...

Radial Spin Texture of the Weyl Fermions in Chiral Tellurium

Majed Chergui, Henrik Moodysson Rønnow, Marco Grioni, Oleg Yazyev, Luc Testa, Daniel Gosalbez Martinez, Philippe Bugnon, Alberto Crepaldi, Luca Moreschini, Mauro Fanciulli, Simon Karl Moser, Gianmarco Gatti, Serhii Polishchuk

Trigonal tellurium, a small-gap semiconductor with pronounced magneto-electric and magneto-optical responses, is among the simplest realizations of a chiral crystal. We have studied by spin- and angle-resolved photoelectron spectroscopy its unconventional ...
