Scalable Robust MCTS with Anytime Deterministic Optimality Guarantees
Tomer Massas, Vadim Indelman
MDP planners often rely on nominal transition models that may differ from the true dynamics. Robust MDP planning accounts for this uncertainty through a set of admissible models, b…
Atom diffraction in the strong-coupling regime
Carina Kanitz, Jakob Bühler, François Aguillon +6
Analytic methods based on matter-wave diffraction are a cornerstone in condensed-matter research, providing access to static and dynamic materials properties down to the atomic lev…
Diffraction of fast heavy noble gas atoms, Ar, Kr and Xe on a LiF(001) surface Changing the tip of a 'perfect' AFM
Debiossac Maxime, Pan Peng, Kanitz Carina +1
We investigate experimentally the diffraction of fast atoms of noble gas on a LiF(100) crystal oriented along the [100] and [110] directions. The wavelengths are so short that the…
Diffraction of atomic matter waves through a 2D crystal
Carina Kanitz, Jakob Bühler, Vladimír Zobač +4
Diffraction of atoms from surfaces provides detailed insights into structures, interactions, and dynamical processes. However, currently the method is limited to measurements in re…
Hollow-core fiber loading of nanoparticles into ultra-high vacuum
Stefan Lindner, Paul Juschitz, Jakob Rieser +4
Many experiments in the field of optical levitation with nanoparticles today are limited by the available technologies for particle loading. Here we introduce a new particle loadin…
Elastic and inelastic diffraction of fast neon atoms on a LiF surface
Maxime Debiossac, Peng Pan, Philippe Roncin
Grazing incidence fast atom diffraction has mainly been investigated with helium atoms, considered as the best possible choice for surface analysis. This article presents experimen…
Convergence to the asymptotic large deviation limit
Maxime Debiossac, Nikolai Kiesel, Eric Lutz
Large deviation theory offers a powerful and general statistical framework to study the asymptotic dynamical properties of rare events. The application of the formalism to concrete…
Optimal time-entropy bounds and speed limits for Brownian thermal shortcuts
Luís Barbosa Pires, Rémi Goerlich, Arthur Luna da Fonseca +4
By controlling in real-time the variance of the radiation pressure exerted on an optically trapped microsphere, we engineer temperature protocols that shortcut thermal relaxation w…
Temperature dependence in fast-atom diffraction at surfaces
Peng Pan, Maxime Debiossac, Philippe Roncin
Grazing incidence fast atom diffraction at crystal surfaces (GIFAD or FAD) has demonstrated coherent diffraction both at effective energies close to one eV ( 14 pm…
MAQRO -- BPS 2023 Research Campaign Whitepaper
Rainer Kaltenbaek, Markus Arndt, Markus Aspelmeyer +43
The objective of the proposed MAQRO mission is to harness space for achieving long free-fall times, extreme vacuum, nano-gravity, and cryogenic temperatures to test the foundations…
Non-Markovian feedback control and acausality: an experimental study
Maxime Debiossac, Martin Luc Rosinberg, Eric Lutz +1
Causality is an important assumption underlying nonequilibrium generalizations of the second law of thermodynamics known as fluctuation relations. We here experimentally study the…
Nonequilibrium control of thermal and mechanical changes in a levitated system
Markus Rademacher, Michael Konopik, Maxime Debiossac +3
Fluctuation theorems are fundamental extensions of the second law of thermodynamics for small nonequilibrium systems. While work and heat are equally important forms of energy exch…
Refraction of fast Ne atoms in the attractive well of LiF(001) surface
Maxime Debiossac, Philippe Roncin, A. G. Borisov
Ne atoms with energies up to 3 keV are diffracted under grazing angles of incidence from a LiF(001) surface. For a small momentum component of the incident beam perpendicular to th…
Thermodynamics of continuous non-Markovian feedback control
Maxime Debiossac, David Grass, Jose Joaquin Alonso +2
Feedback control mechanisms are ubiquitous in science and technology, and play an essential role in regulating physical, biological and engineering systems. The standard second law…
