Nonlocal Metaspire: A Scalable Elastic Material Platform With Decoupled Mechanical Modes

open access: yesAdvanced Materials, EarlyView.
Nonlocal Metaspire introduces sequential rotation to realize wider scalability in implementing complex nonlocal couplings in elastic metamaterials while suppressing unintended mode coupling. Numerical results clarify the underlying wave motions, demonstrate mode‐decoupled roton and maxon formation, and support a straightforward extension to higher ...

Internal-wave reflection from uniform slopes: higher harmonics and Coriolis effects [PDF]

open access: yesNonlinear Processes in Geophysics, 2006
Weakly nonlinear reflection of internal waves from uniform slopes produces higher harmonics and mean fields; the expressions are here derived for constant stratification and with Coriolis effects fully included, i.e. the horizontal component of the

Measuring and Manipulating Density of States in Two‐Dimensional Materials With Electrochemical Capacitance

open access: yesAdvanced Materials Interfaces, EarlyView.
We report electrochemical quantum capacitance spectroscopy as an ambient, in situ probe for defect‐mediated electronic structure at 2D material interfaces. Using monolayer MoS2, the method resolves band edges and vacancy states, tracks sulfur‐vacancy evolution during hydrogen evolution, and links interfacial density‐of‐states changes to nearly ...

Importance of including higher signal harmonics in the modeling of extreme mass-ratio inspirals

open access: yes, 2023
Extreme mass-ratio inspirals (EMRIs) are the most potential sources detectable by the Laser Interferometer Space Antenna (LISA). To analyze the influence of higher harmonics on parameter estimation for EMRIs efficiently, we use the waveform model that ...
