Unveiling radial breathing mode in a particle-on-mirror plasmonic nanocavity [PDF]
Nanophotonics, 2022 Plasmonic radial breathing mode (RBM), featured with radially oscillating charge density, arises from the surface plasmon waves confined in the flat nanoparticles. The zero net dipole moment endows the RBM with an extremely low radiation yet a remarkable

On the onset of breathing mode in Hall thrusters and the role of electron mobility fluctuations
Frontiers in Physics, 2022 Breathing mode is an ionization instability which is observed ubiquitously in the operation of Hall thrusters. It is recognized as a relatively low frequency (10–30 kHz) longitudinal oscillation of the discharge current and the plasma parameters ...

Breathing mode selectively modulates brain-wide functional connectivity. [PDF]
PLoS ONEWhile respiration is known to rhythmically modulate brain activity, how different breathing modes (nasal vs. oral) affect frequency-specific large-scale neural connectivity in humans remains unexplored. We used resting-state functional magnetic resonance

Collective excitations in two-dimensional SU(N) Fermi gases with tunable spin [PDF]
Physical Review Research, 2020 We measure collective excitations of a harmonically trapped two-dimensional (2D) SU(N) Fermi gas of ^{173}Yb confined to a stack of layers formed by a one-dimensional optical lattice.

Computational fluid dynamics simulation of upper airway flow and soft tissue deformation in a mouth-breathing patient: a case study [PDF]
BMC Oral HealthObjective The primary objective of this study was to establish a three-dimensional fluid-structure interaction (FSI) model to compare the biomechanical effects of three distinct breathing modes—nasal (NA), oronasal (ONA), and oral (OA) ventilation—on ...

Numerical and Experimental Investigation of Longitudinal Oscillations in Hall Thrusters
Aerospace, 2021 One of the main oscillatory modes found ubiquitously in Hall thrusters is the so-called breathing mode. This is recognized as a relatively low-frequency (10–30 kHz), longitudinal oscillation of the discharge current and plasma parameters.
