Anomalous‐Chern Steering of Topological Nonreciprocal Guided Waves
Romain Christophe Rémy Fleury, Haoye Qin, Zhechen Zhang, Qiaolu Chen
Nonreciprocal topological edge states based on external magnetic bias have been regarded as the last resort for genuine unidirectional wave transport, showing superior robustness over topological states with preserved time-reversal symmetry. However, fast ...
2024Thermodynamic bounds on time-reversal asymmetry
Quantifying irreversibility of a system using finite information constitutes a major challenge in stochastic thermodynamics. We introduce an observable that measures the time-reversal asymmetry between two states after a given time lag. Our central result ...
College Pk2023Demonstration of a Plasmonic Nonlinear Pseudodiode
Olivier Martin, Karim Achouri, Andrei Kiselev, Sergejs Boroviks
We demonstrate a nonlinear plasmonic metasurface that exhibits strongly asymmetric second-harmonic generation: nonlinear scattering is efficient upon excitation in one direction, and it is substantially suppressed when the excitation direction is reversed, ...
AMER CHEMICAL SOC2023The arrow-of-time in neuroimaging time series identifies causal triggers of brain function
Dimitri Nestor Alice Van De Ville, Thomas William Arthur Bolton, Maria Giulia Preti, Enrico Amico, Raphaël Pierre Liégeois
Moving from association to causal analysis of neuroimaging data is crucial to advance our understanding of brain function. The arrow-of-time (AoT), that is, the known asymmetric nature of the passage of time, is the bedrock of causal structures shaping phy ...
WILEY2023Two-dimensional Hubbard model at finite temperature: Weak, strong, and long correlation regimes
We investigate the momentum-resolved spin and charge susceptibilities, as well as the chemical potential and double occupancy in the two-dimensional Hubbard model as functions of doping, temperature, and interaction strength. Through these quantities, we i ...
AMER PHYSICAL SOC2022Time-reversed Impulse Response Haptic Demonstrator
The EPFL - LAI is investigating novel haptic technologies for rendering rich vibrotactile feedback in digital musical interfaces. The main objective is to develop an interactive surface that can render multitouch vibrotactile stimuli. As part of this resea ...
2022Finite-temperature materials modeling from the quantum nuclei to the hot electron regime
Michele Ceriotti, Chiheb Ben Mahmoud, Nataliya Lopanitsyna
Atomistic simulations provide insights into structure-property relations on an atomic size and length scale, that are complementary to the macroscopic observables that can be obtained from experiments. Quantitative predictions, however, are usually hindere ...
2021Bell Diagonal and Werner State Generation: Entanglement, Non-Locality, Steering and Discord on the IBM Quantum Computer
Nicolas Macris, Su Yeon Chang, Marc-André Dupertuis, Chun Lam Chan, Samuel Bosch, Nicolas Schwaller, Frédéric Gessler
We propose the first correct special-purpose quantum circuits for preparation of Bell diagonal states (BDS), and implement them on the IBM Quantum computer, characterizing and testing complex aspects of their quantum correlations in the full parameter spa ...
2021Arbitrarily high time bandwidth performance in a nonreciprocal optical resonator with broken time invariance
Camille Sophie Brès, Hatice Altug, Davide Grassani, Ivan Cardea, Kosmas Tsakmakidis, Simon Julien Fabbri
Most present-day resonant systems, throughout physics and engineering, are characterized by a strict time-reversal symmetry between the rates of energy coupled in and out of the system, which leads to a trade-off between how long a wave can be stored in th ...
