Quantum–Electromagnetic Coupling in Time Domain Simulations Using COMSOL Multiphysics®

Gian Marco Zampa1, Davide Mencarelli1, Luca Pierantoni1
1Università Politecnica delle Marche

INTRODUCTION The coupling of the Schrödinger and Maxwell equations allows to predict the self-generated electromagnetic (EM) field for a quantum charged particle moving in a domain. Such problem is really challenging, and it must be investigated in order to simulate the behavior of a ... Read More

Simulation studies of the MADMAX dielectric haloscope for Dark Matter axion research

Antonios Gardikiotis1, Stefan Knirck2, Jan Schuette-Engel1
1University of Hamburg, Germany
2Max-Planck-Institut für Physik, Munich, Germany

The axion is an excellent cold dark matter (CDM) candidate, originally proposed to solve the strong CP problem in strong interactions. A novel method to detect galactic axions is by using their conversion to electromagnetic waves from boundaries between materials of different dielectric ... Read More

Time Domain Simulations of Nonlinear Plasma Conductivity by Microwave Inductive Coupling

Horia-Eugen Porteanu1
1Leibniz-Institut für Höchstfrequenztechnik, Berlin, Germany

Exciting plasma in inductive mode is attractive due to the high electron density and the absence of ion interaction with the reactor walls. However, any real system excites plasma at low power in capacitive mode with strong interaction with the walls. The transition from one mode to the ... Read More

Dielectric Haloscope Simulation and the Quest for Dark Matter Axions

Xiaoyue Li1, Olaf Reimann1, Chang Lee1, Derek Strom1
1Max-Planck-Institut für Physik, München, Germany

The nature of dark matter remains one of the most pressing puzzles in physics. The MAgnetized Disc and Mirror Axion eXperiment (MADMAX) is a dielectric haloscope dedicated to the search for QCD axion dark matter in the mass range of 40 - 400 µeV. The design of the experiment consists of ... Read More

With the Release 14, the Third Generation Partnership Project (3GPP) [3GPP TR 38.913 V0.4.0, 2016] paved the way to the possibility of delivering digital television services on mobile terminals, such as smartphones and tablets, overcoming all the limitations which characterize the ... Read More

Plasmonic nanoantenna for energy-efficient All-Optical Switching

Maxime Vergès1, Julius Hohlfeld1, Michel Hehn1, Stéphane Mangin1, Artëm Larin2, Roman Savelev2, Dmitry Zuev2, Colas Joannin3
1Université de Lorraine, Institut Jean Lamour, Nancy, France
2ITMO University, St. Petersburg 197101, Russia
3COMSOL France SAS, Grenoble, France

Our goal is to create plasmons to enhance All Optical Switching (AOS) of the magnetization. We used a finite-element model in order to understand the impact of plasmonic disk-shaped nanoantennas on magneto-optical effects. We first tested our model without an antenna and compare it with ...

AC and DC theoretical modeling of a MoS2-FET with COMSOL Multiphysics

N. Pelagalli1, D. Mencarelli1, L. Pierantoni1
1Marche Polytechninc University, Ancona, AN, Italy

Transition metal dichalcogenides (TMDCs) have attracted the interest of researchers because of their physical properties, such as tunabilitiy, non-zero bandgap, gas sensing and superconductivity. One of the most studied TMDC is monolayer MoS2, for this reason we present how COMSOL can be ... Read More
