An ultra-low field SQUID magnetometer for measuring antiferromagnetic and weakly remanent magnetic materials at low temperatures
(Journal article, 2023)A novel setup for measuring magnetic fields of antiferromagnets (i.e., quadrupolar or higher-order magnetic fields) and generally weakly remanent magnetic materials is presented. The setup features a highly sensitive ... -
Ultra-robust icephobic coatings with high toughness, strong substrate adhesion and self-healing capability
(Peer reviewed; Journal article, 2022)Enabling surfaces with passive anti-icing properties is an emerging, facile, economical, and energy-saving strategy to mitigate the harm caused by ice accretion. However, the combination of icephobicity and robustness still ... -
Ultra-short pulsed Tm- and Er-doped all-fiber MOPA lasers and supercontinuum sources.
(Doctoral thesis, 2016-12-12)The present work describes the results of the development of a family of novel diode-pumped ultra-short and short pulsed Er- and Tm-fiber laser systems in the “eye-safe” near- and mid-Infrared (mid-IR) wavelength range for ... -
Ultra-Short-Chain PFASs in the Sources of German Drinking Water: Prevalent, Overlooked, Difficult to Remove, and Unregulated
(Peer reviewed; Journal article, 2022)Per- and polyfluoroalkyl substances (PFASs) have been a focal point of environmental chemistry and chemical regulation in recent years, culminating in a shift from individual PFAS regulation toward a PFAS group regulatory ... -
Ultrabroad Continuous-Wave Tuning of Ceramic Cr:ZnSe and Cr:ZnS Lasers
(Chapter, 2010)Using a single set of optics, we demonstrate ultrabroad tuning over more than 1300 nm from 1973 to 3349 nm in Cr:ZnSe and from 1962 to 3195 nm in Cr:ZnS at <10 GHz linewidth. -
Ultrafast control of spin interactions in honeycomb antiferromagnetic insulators
(Journal article; Peer reviewed, 2019)Light enables the ultrafast, direct, and nonthermal control of the exchange and Dzyaloshinskii-Moriya interactions. We consider two-dimensional honeycomb lattices described by the Kane-Mele-Hubbard model at half filling ... -
Ultrafast fiber-based lasers beyond 2 µm
(Chapter, 2017)The talk reviews recent advances in fiber based ultrafast mid-IR lasers and frequency combs, outlines the trends in materials as well as novel approaches for generation of ultra-broadband spectra above 2 mm. -
Ultrafast generation and dynamics of isolated skyrmions in antiferromagnetic insulators
(Peer reviewed; Journal article, 2019)Based on atomistic spin dynamics simulations, we report the ultrafast generation of single antiferromagnetic (AFM) skyrmions in a confined geometry. This process is achieved through an effective magnetic field induced by ... -
