DOI: 10.1038/s41586-021-04284-7
Abstract: The flow of water in carbon nanochannels has defied understanding thus far1, with accumulating experimental evidence for ultra-low friction, exceptionally high water flow rates and curvature-dependent hydrodynamic slippage2-5. In particular, the mechanism of water-carbon friction… read more here.

Abstract: Bodies in relative motion, spatially separated in vacuum, experience a tiny friction force known as quantum friction. This force has eluded experimental detection so far due to its small magnitude and short range. Herein, we… read more here.

DOI: 10.1103/physreva.98.032507
Abstract: We study quantum friction and Casimir forces with a full-relativistic formalism for atoms modelled as Unruh-DeWitt detectors in the presence of arbitrary macroscopic objects. We consider the general case of atoms with arbitrary relativistic trajectories… read more here.

DOI: 10.1103/physrevb.111.075403
Abstract: In this work, we develop an analytical framework to understand quantum friction across distinct stability regimes, providing approximate expressions for frictional forces both in the deep stable regime and near the critical threshold of instability.… read more here.

DOI: 10.1103/physrevb.98.125405
Abstract: We present a theoretical description of energy transfer processes between two noncontact quasi-twodimensional crystals separated by distance a, oscillating with frequency ω0 and amplitude ρ0, and compare it with the case of two quasi-two-dimensional crystals… read more here.
