Helimagnons and Skyrmion Dynamics in Cu2OSeO3 and Fe/Gd Multilayers Explored by Brillouin Light Scattering and X-ray Microscopy
Spin dynamics in skyrmion hosting materials provide novel functionality in magnonics because of the formation of a novel magnon band structure and the nanoscale sizes of magnetic skyrmions. In this thesis, we explore the spin dynamics in the chiral magnet ...
EPFL2021Emergent nonlinear phenomena in a driven dissipative photonic dimer
Tobias Kippenberg, Rui Ning Wang, Mikhail Churaev, Kenichi Komagata, Junqiu Liu, Hairun Guo, Alexey Tikan
Collective effects leading to spatial, temporal or spatiotemporal pattern formation in complex nonlinear systems driven out of equilibrium cannot be described at the single-particle level and are therefore often called emergent phenomena. They are characte ...
NATURE RESEARCH2021Quantum phase transitions beyond Landau-Ginzburg theory in one-dimensional space revisited
The phase diagram of the quantum spin-1/2 antiferromagnetic J(1)-J(2) XXZ chain was obtained by Haldane using bosonization techniques [Haldane, Phys. Rev. B 25, 4925 (1982); 26, 5257 (1982)]. It supports three distinct phases for 0
2019Intermode Breather Solitons in Optical Microresonators
Tobias Kippenberg, Michael Wolfgang Geiselmann, Junqiu Liu, Maxim Karpov, Hairun Guo, Martin Hubert Peter Pfeiffer, Erwan Guillaume Albert Lucas, Miles Henry Anderson, John David Jost
Dissipative solitons can be found in a variety of systems resulting from the double balance between dispersion and nonlinearity, as well as gain and loss. Recently, they have been observed to spontaneously form in Kerr nonlinear microresonators driven by a ...
2017On the global structure of deformed Yang-Mills theory and QCD(adj) on R-3 x S-1
Spatial compactification on R(3)xS(L)(1), at small S-1-size L often leads to a calculable vacuum structure, where various "topological molecules" are responsible for confinement and the realization of the center and discrete chiral symmetries. Within this ...
Springer2015Softening and hardening transitions in ferroelectric Pb(Zr,Ti)O3 ceramics
Hysteretic and nonlinear dielectric behaviour in ferroelectric ceramics has been of interest since 1950s, when these materials found application in various electronic devices. Presently, these phenomena concern with important areas of science, technology a ...
