Load-dependent resistive-force theory for helical filaments
Pyae Hein Htet, Eric Lauga
The passive rotation of rigid helical filaments is the propulsion strategy used by flagellated bacteria and some artificial microswimmers to navigate at low Reynolds numbers. In a…

Analytical methods for cytoplasmic streaming in elongated cells
Pyae Hein Htet, Eric Lauga
Cytoplasmic streaming, the coherent flow of cytoplasm, plays a critical role in transport and mixing over large scales in eukaryotic cells. In many large cells, this process is dri…

Hydrodynamic hovering of swimming bacteria above surfaces
Pyae Hein Htet, Debasish Das, Eric Lauga
Flagellated bacteria are hydrodynamically attracted to rigid walls, yet past work shows a 'hovering' state where they swim stably at a finite height above surfaces. We use numerics…
