Mechanical quantum sensing in the search for dark matter [PDF]

open access: yes, 2021
Numerous astrophysical and cosmological observations are best explained by the existence of dark matter, a mass density which interacts only very weakly with visible, baryonic matter.

Measurement of nonlinear piezoelectric coefficients using a micromechanical resonator [PDF]

open access: yes, 2018
We describe and demonstrate a method by which the nonlinear piezoelectric properties of a piezoelectric material may be measured by detecting the force that it applies on a suspended micromechanical resonator at one of its mechanical resonance ...

Topological plasma transport from a diffusion view

open access: yes, 2023
Recent studies have identified plasma as a topological material. Yet, these researches often depict plasma as a fluid governed by electromagnetic fields, i.e., a classical wave system.

Automated design of multi junction solar cells by genetic approach : reaching the >50% efficiency target [PDF]

open access: yes, 2017
The proper design of the multi-junction solar cell (MJSC) requires the optimisation search through the vast parameter space, with parameters for the proper operation quite often being constrained, like the current matching throughout the cell.

Novel color center platforms enabling fundamental scientific discovery

open access: yes, 2020
Color centers are versatile systems that generate quantum light, sense magnetic fields and produce spin-photon entanglement. We review how these properties have pushed the limits of fundamental knowledge in a variety of scientific disciplines, from ...

Assessing Phonon Coherence Using Spectroscopy

open access: yes, 2022
As a fundamental physical quantity of thermal phonons, temporal coherence participates in a broad range of thermal and phononic processes, while a clear methodology for the measurement of phonon coherence is still lacking.

Quantum gas-enabled direct mapping of active current density in percolating networks of nanowires

open access: yes, 2023
Electrically percolating nanowire networks are amongst the most promising candidates for next-generation transparent electrodes. Scientific interest in these materials stems from their intrinsic current distribution heterogeneity, leading to phenomena ...

Injection locking at fractional frequencies of magnetic tunnel junction (MTJ)-based read sensors' ferromagnetic resonance modes

open access: yes, 2019
Being nonlinear dynamic systems, magnetic read sensors should respond to an excitation signal of a frequency considerably different from their natural ferromagnetic resonance (FMR) frequencies.
