Spatiotemporal energy‐density distribution of time‐reversed electromagnetic fields
Marcos Rubinstein, Farhad Rachidi-Haeri, Hamidreza Karami, Elias Per Joachim Le Boudec, Nicolas Mora Parra
Time reversal exploits the invariance of electromagnetic wave propagation in reciprocal and lossless media to localize radiating sources. Time-reversed measurements are back-propagated in a simulated domain and converge to the unknown source location. The ...

2023Impact of quantum-chemical metrics on the machine learning prediction of electron density
Ksenia Briling, Alberto Fabrizio
Machine learning (ML) algorithms have undergone an explosive development impacting every aspect of computational chemistry. To obtain reliable predictions, one needs to maintain a proper balance between the black-box nature of ML frameworks and the physics ...
AMER INST PHYSICS2021Analysis of the lightning production of convective cells
Marcos Rubinstein, Mohammad Azadifar, Antonio Sunjerga, Amirhossein Mostajabi, Jacopo Grazioli, Nikola Besic, Urs Martin Germann
This paper presents an analysis of the lightningproduction of convective cells. The cells were detected by the MeteoSwiss Thunderstorms Radar Tracking (TRT) algorithm in the course of a lightning measurement campaign thattook place in the summer of 2017 in ...
2019Cryo-CMOS Electronics for Quantum Computing Applications
Quantum computers hold the promise to solve some of the most complex problems of today. The core of a quantum computer is a quantum processor, which is composed of quantum bits (qubits). Qubits are fragile and their state needs to be corrected in real time ...
IEEE2019Quantum Brownian Motion at Strong Dissipation Probed by Superconducting Tunnel Junctions
Klaus Kern, Markus Etzkorn, Jacob Senkpiel, Berthold Jäck
We have investigated the phase dynamics of a superconducting tunnel junction at ultralow temperatures in the presence of high damping, where the interaction with environmental degrees of freedom represents the leading energy scale. In this regime, theory p ...
Amer Physical Soc2017Examples of algebraic groups of type G (2) having the same maximal tori
Answering a question of A. Rapinchuk, we construct examples of non-isomorphic semisimple algebraic groups H (1) and H (2) of type G (2) having coherently equivalent systems of maximal k-tori. ...
Maik Nauka/Interperiodica/Springer2016Flexure-based multi-degrees-of-freedom in-vivo force sensors for medical instruments
Simon Nessim Henein, Charles Baur, Marine Chantal Elisabeth Geneviève Clogenson, Sebastian Krzysztof Fifanski, José Luis Rivera Gutiérrez
This paper presents novel multi-degrees-of-freedom force sensors based on flexures used as mecano-optical transducers (named flexure body) and white light interferometers used as opto-electrical transducers. Together, these transducers make up a load cell ...
2016Single Photon Counting UV Solar-Blind Detectors Using Silicon and III-Nitride Materials
Edoardo Charbon, Preethi Padmanabhan
Ultraviolet (UV) studies in astronomy, cosmology, planetary studies, biological and medical applications often require precision detection of faint objects and in many cases require photon-counting detection. We present an overview of two approaches for ac ...
2016Milli Newton force measurement and control for micro ultrasonic machining
Ultrasonic machining is performed using closed-loop Z-axis position and force control. Micromachining requires tools smaller than 100 micrometers in diameter, necessitating the use of forces in the low mN range. ...
