Ultrawide Bandwidth Optomechanical Magnetometry Using Flux Concentration
Benjamin J. Carey, Nathaniel Bawden, Fernando Gottardo +4
Low-frequency magnetic fields carry vital information for neuroscience, navigation, and Earth science. However, they are generally weak, making it challenging to measure them with…
Solitary waves in a phononic integrated circuit
Timothy M. F. Hirsch, Xiaoya Jin, Nicolas P. Mauranyapin +6
Solitons are universal nonlinear excitations that appear in settings as varied as optics, water waves, and quantum gases [1-5]. While reduced models of soliton dynamics are well es…
