Topological photonic transport in disordered scattering networks
This Ph.D. thesis unveils the unique topological phenomena occurring in such networks, focusing on the intricate interplay between their Floquet topology, the presence of disorder, and their unitary scattering at microscopic and macroscopic scales. Using t ...
EPFL2024Nonlinear optical diode effect in a magnetic Weyl semimetal
Philip Johannes Walter Moll, Chunyu Guo, Hao Yang
Diode effects are of great interest for both fundamental physics and modern technologies. Electrical diode effects (nonreciprocal transport) have been observed in Weyl systems. Optical diode effects arising from the Weyl fermions have been theoretically co ...
Nature Portfolio2024Complementary screening for quantum spin Hall insulators in two-dimensional exfoliable materials
Nicola Marzari, Davide Campi, Antimo Marrazzo, Davide Grassano
Quantum spin Hall insulators are a class of topological materials that has been extensively studied during the past decade. One of their distinctive features is the presence of a finite band gap in the bulk and gapless, topologically protected edge states ...
College Pk2023Crystalline or amorphous? A critical evaluation of phenomenological phase selection rules
In this work, we reviewed the available phase selection rules comprising atomic size and topological aspects, entropies, enthalpies, melting points, valence and itinerant electron concentrations, as well as electronegativity, and validated them using a car ...
ELSEVIER SCI LTD2023Topology, Oxidation States, and Charge Transport in Ionic Conductors
Recent theoretical advances, based on a combination of concepts from Thouless' topological theory of adiabatic charge transport and a newly introduced gauge-invariance principle for transport coefficients, have permitted to connect (and reconcile) Faraday' ...
WILEY-V C H VERLAG GMBH2022Single-Chain Nanoparticles for Intracellular Drug Delivery
Single-chain nanoparticles (SCNPs) are a type of polymeric nanoparticles formed by collapsing/folding individual polymer chains via intra-molecular interactions. Their emergence holds promise to construct sub-20 nm polymeric nanoparticles with defined stru ...

At the crossroads of the ethnography of scholarly practices and digital humanities, this study proposes to consider the exploratory aspect of the scientific activity as an intellectual path through a corpus made accessible by an online platform. My case st ...
2022Experimental Observation and Spin Texture of Dirac Node Arcs in Tetradymite Topological Metals
Emmanouil Frantzeskakis, Ji Dai
We report the observation of a nontrivial spin texture in Dirac node arcs, i.e., novel topological objects formed when Dirac cones of massless particles extend along an open one-dimensional line in momentum space. We find that such states are present in al ...
AMER PHYSICAL SOC2021Observation 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 ...
