Realization of an atomic quantum Hall system in four dimensions
Modern condensed matter physics relies on the concept of topology to classify matter, from quantum Hall systems to topological insulators. Engineered systems, benefiting from synthetic dimensions, can potentially give access to topological states predicted ...
Amer Assoc Advancement Science2024Topological 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 ...
EPFL2024Anomalous‐Chern Steering of Topological Nonreciprocal Guided Waves
Romain Christophe Rémy Fleury, Haoye Qin, Zhechen Zhang, Qiaolu Chen
Nonreciprocal topological edge states based on external magnetic bias have been regarded as the last resort for genuine unidirectional wave transport, showing superior robustness over topological states with preserved time-reversal symmetry. However, fast ...
2024Experimental observation of topological transition in linear and nonlinear parametric oscillators
Romain Christophe Rémy Fleury, Benjamin Apffel
Parametric oscillators are examples of externally driven systems that can exhibit two stable states with opposite phase depending on the initial conditions. In this work, we propose to study what happens when the external forcing is perturbed by a continuo ...
2024Phase of Topological Lattice with Leaky Guided Mode Resonance
Kirsten Emilie Moselund, Chang Won Lee
Topological nature in different areas of physics and electronics has often been characterized and controlled through topological invariants depending on the global properties of the material. The validity of bulk-edge correspondence and symmetry-related to ...
Basel2023Complementary 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 Pk2023Seeding and Emergence of Composite Skyrmions in a van der Waals Magnet
Klaus Kern, Marko Burghard, Lukas Powalla
Topological charge plays a significant role in a range of physical systems. In particular, observations of real-space topological objects in magnetic materials have been largely limited to skyrmions - states with a unitary topological charge. Recently, mor ...
WILEY-V C H VERLAG GMBH2023Topological Effects in Carbon-based Two-dimensional Nanostructures
Recent advances on low-dimensional and topological materials has greatly inspired the research in condensed matter physics. This thesis is devoted to the computational and theoretical study of topological effects in two-dimensional materials, especially na ...

Anna Fontcuberta i Morral, Didem Dede, Valerio Piazza, Nicholas Paul Morgan
Selective area epitaxy is a promising approach to definenanowirenetworks for topological quantum computing. However, it is challengingto concurrently engineer nanowire morphology, for carrier confinement,and precision doping, to tune carrier density. We re ...
AMER CHEMICAL SOC2023Anomalous topological waves in strongly amorphous scattering networks
Romain Christophe Rémy Fleury, Zhechen Zhang, Pierre Delplace
Topological insulators are crystalline materials that have revolutionized our ability to control wave transport. They provide us with unidirectional channels that are immune to obstacles, defects, or local disorder and can even survive some random deformat ...
