Fluctuation-induced ionic friction at solid-electrolyte interfaces
Damien Toquer, Baptiste Coquinot, Nikita Kavokine +1
In this article, we explore how transport at a solid--electrolyte interface is affected by the internal fluctuations of the solid and quantify the role of solid excitations on ioni…
Crossing the Rotational Sound Barrier in a Quantum Solvent
Baptiste Coquinot, Giacomo Bighin, Mikhail Lemeshko +1
Molecules embedded in superfluids provide an experimentally controllable platform for investigating impurity physics. Here, we investigate a driven molecule rotating in a superflui…
Optical centrifuge as a probe of strong dissipative coupling between a molecular rotor and superfluid helium
Ian MacPhail-Bartley, Sören E. Mahr, Cameron E. Peters +7
A macroscopic manifestation of superfluidity is that objects moving through liquid helium experience negligible friction below the Landau critical velocity. How this frictionless m…
Fluctuation-induced and quantum effects in nanofluidic transport
Adrien Sutter, Peter Gispert, Baptiste Coquinot +2
The hydrodynamic wall has traditionally been considered a featureless object, whose only role is to provide a boundary for fluid flow. Yet, there is now ample evidence that at nano…
Exciton-mediated optical control of liquid-solid friction
Timur Pryadilin, Alexey Kavokin, Baptiste Coquinot
Interfacial friction in nanofluidic systems can arise from fluctuation-induced coupling between liquid charge fluctuations and the internal excitations of the confining solid. Here…
Architecting mechanosensitive nanofluidic transport in graphite nanoslits
Mathieu Lizée, Zhijia Zhang, Baptiste Coquinot +2
Mechanosensitive ion transport plays a central role in enabling living systems to perceive and adapt to their environment through the deformation of soft, embedded ion channels. In…
Hydrodynamic permeability of fluctuating porous membranes
Albert Dombret, Adrien Sutter, Baptiste Coquinot +3
In this paper we examine how porosity fluctuations affect the hydrodynamic permeability of a porous matrix or membrane. We introduce a fluctuating Darcy model, which couples the Na…
Fluctuation-Induced Supersolidity at the Superfluid-Solid Interface
Baptiste Coquinot, Ragheed Alhyder, Alberto Cappellaro +1
Supersolidity, combining superfluid and crystalline orders, has been realized in dipolar Bose-Einstein condensates by tuning interatomic interactions. Here we show that supersolidi…
Direct imaging elucidates ionic memory in two-dimensional nanochannels
Kalluvadi Veetil Saurav, Nathan Ronceray, Baptiste Coquinot +5
Nanofluidic memristors promise brain-inspired information processing with ions, yet their microscopic origin remains debated. So far, ionic memory has been attributed to ion-specif…
Electron-electrolyte coupling in AC transport through nanofluidic channels
Baptiste Coquinot, Mathieu Lizée, Lydéric Bocquet +1
The transport properties of nanofluidic channels are usually studied under constant (DC) voltage or pressure driving. However, the frequency response under sinusoidal (AC) drivings…
Momentum tunnelling between nanoscale liquid flows
Baptiste Coquinot, Anna T. Bui, Damien Toquer +4
The world of nanoscales in fluidics is the frontier where the continuum of fluid mechanics meets the atomic, and even quantum, nature of matter. While water dynamics remains largel…
Anomalous friction of supercooled glycerol on mica
Mathieu Lizée, Baptiste Coquinot, Guilhem Mariette +2
The fundamental understanding of friction of liquids on solid surfaces remains one of the key knowledge gaps in the transport of fluids. While the standard perspective emphasizes t…
Hydroelectric energy conversion of waste flows through hydroelectronic drag
Baptiste Coquinot, Lydéric Bocquet, Nikita Kavokine
Hydraulic energy is a key component of the global energy mix, yet there exists no practical way of harvesting it at small scales, from flows at low Reynolds number. This has trigge…
Drastic reduction of dynamic liquid-solid friction in supercooled glycerol
Mathieu Lizée, Guilhem Mariette, Baptiste Coquinot +2
This study addresses the influence of internal liquid dynamics on liquid-solid friction. Taking advantage of the wide range of relaxation timescales in supercooled liquids, we use…
Collective modes and quantum effects in two-dimensional nanofluidic channels
Baptiste Coquinot, Maximilian Becker, Roland R. Netz +2
Nanoscale fluid transport is typically pictured in terms of atomic-scale dynamics, as is natural in the real-space framework of molecular simulations. An alternative Fourier-space…

The interface between a liquid and a solid is the location of plethora of intrincate mechanisms at the nanoscale, at the root of their specific emerging properties in natural proce…
Quantum feedback at the solid-liquid interface: flow-induced electronic current and its negative contribution to friction
Baptiste Coquinot, Lydéric Bocquet, Nikita Kavokine
An electronic current driven through a conductor can induce a current in another conductor through the famous Coulomb drag effect. Similar phenomena have been reported at the inter…
A General Metriplectic Framework with Application to Dissipative Extended Magnetohydrodynamics
Baptiste Coquinot, Philip J. Morrison
General equations for conservative yet dissipative (entropy producing) extended magnetohydrodynamics are derived from two-fluid theory. Keeping all terms generates unusual cross-ef…
