Pair-exchange dynamics of magnetohydrodynamic turbulence
Jean-Mathieu Teissier, Wolf-Christian Müller
Nonlinear interactions in incompressible magnetohydrodynamic (MHD) and Navier-Stokes turbulence involve three spatial fluctuations conservatively exchanging, e.g., energy. The math…
VCSEL-based CPO for Scale-Up in A.I. Datacenter. Status and Perspectives
Manuel Kohli, Jean Teissier
The drastic increase of bandwidth demands in AI datacenters requires new solutions with low power consumption and high bandwidth densities. Further increasing the total bandwidth w…
Emergence of magnetic structure in supersonic isothermal magnetohydrodynamic turbulence
Jean-Mathieu Teissier, Wolf-Christian Müller
The inverse transfer of magnetic helicity is a fundamental process which may explain large scale magnetic structure formation and sustainement. Until very recently, direct numerica…
High-order finite-volume integration schemes for subsonic magnetohydrodynamics
Jean-Mathieu Teissier, Wolf-Christian Müller
We present an efficient dimension-by-dimension finite-volume method which solves the adiabatic magnetohydrodynamics equations at high discretization order, using the constrained-tr…
Higher-order magnetohydrodynamic numerics
Jean-Mathieu Teissier, Wolf-Christian Müller
In this chapter, we aim at presenting the basic techniques necessary to go beyond the widely accepted paradigm of second-order numerics. We specifically focus on finite-volume sche…
Stability of plasmas through magnetic helicity
Simon Candelaresi, Fabio Del Sordo
Magnetic helicity, and more broadly magnetic field line topology, impose constraints on the plasma dynamics. Helically interlocked magnetic rings are in a non-trivial topological s…
Laser cooling of a Planck mass object close to the quantum ground state
Leonhard Neuhaus, Remi Metzdorff, Salim Zerkani +13
Quantum mechanics has so far not been tested for mechanical objects at the scale of the Planck mass . We present an experiment where a 1 m…
Inverse transfer of magnetic helicity in direct numerical simulations of compressible isothermal turbulence: helical transfers
Jean-Mathieu Teissier, Wolf-Christian Müller
The role of the different helical components of the magnetic and velocity fields in the inverse spectral transfer of magnetic helicity is investigated through Fourier shell-to-shel…
Inverse transfer of magnetic helicity in direct numerical simulations of compressible isothermal turbulence: scaling laws
Jean-Mathieu Teissier, Wolf-Christian Müller
The inverse transfer of magnetic helicity is investigated through direct numerical simulations of large-scale-mechanically-driven turbulent flows in the isothermal ideal magnetohyd…
Non-reciprocal coherent dynamics of a single spin under closed-contour interaction
Arne Barfuss, Johannes Kölbl, Lucas Thiel +3
Three-level quantum systems have formed a cornerstone of quantum optics since the discovery of coherent population trapping (CPT) and electromagnetically induced transparency. Key…
Hybrid continuous dynamical decoupling: a photon-phonon doubly dressed spin
Jean Teissier, Arne Barfuss, Patrick Maletinsky
We study the parametric interaction between a single Nitrogen-Vacancy electronic spin and a diamond mechanical resonator in which the spin is embedded. Coupling between spin and os…
A quantum fiber-pigtail
Davide Cadeddu, Jean Teissier, Floris Braakman +7
We present the experimental realization of a quantum fiber-pigtail. The device consists of a semiconductor quantum-dot embedded into a conical photonic wire that is directly connec…
Fourth Order Accurate Finite Volume CWENO Scheme For Astrophysical MHD Problems
Prabal Singh Verma, Jean-Mathieu Teissier, Oliver Henze +1
In this work, a simple fourth-order accurate finite volume semi-discrete scheme is introduced to solve astrophysical magnetohydrodynamics (MHD) problems on Cartesian meshes. Hydrod…
Strong mechanical driving of a single electron spin
Arne Barfuss, Jean Teissier, Elke Neu +2
Quantum devices for sensing and computing applications require coherent quantum systems which can be manipulated in a fast and robust way. Such quantum control is typically achieve…
Resolved sidebands in a strain-coupled hybrid spin-oscillator system
Jean Teissier, Arne Barfuss, Patrick Appel +2
We report on single electronic spins coupled to the motion of mechanical resonators by a novel mechanism based on crystal strain. Our device consists of single-crystalline diamond…
Optical properties of metal-dielectric-metal microcavities in the THz frequency range
Yanko Todorov, Lorenzo Tosetto, Jean Teissier +6
We present an experimental and theoretical study of the optical properties of metal-dielectric-metal structures with patterned top metallic surfaces, in the THz frequency range. Wh…
