Phonon diodes and transistors from magneto-acoustics [PDF]

open access: goldNew Journal of Physics, 2014
By sculpting the magnetic field applied to magneto-acoustic materials, phonons can be used for information processing. Using a combination of analytic and numerical techniques, we demonstrate designs for diodes (isolators) and transistors that are ...

Femtosecond Laser Ablation and Delamination of Functional Magnetic Multilayers at the Nanoscale [PDF]

open access: yesNanomaterials
Laser nanostructuring of thin films with ultrashort laser pulses is widely used for nanofabrication across various fields. A crucial parameter for optimizing and understanding the processes underlying laser processing is the absorbed laser fluence, which

Topologically protected one-way edge mode in networks of acoustic resonators with circulating air flow

open access: yesNew Journal of Physics, 2015
Recent explorations of topology in physical systems have led to a new paradigm of condensed matters characterized by topologically protected states and phase transition, for example, topologically protected photonic crystals enabled by magneto-optical ...

NOISE CONTROL OF VEHICLE DRIVE SYSTEMS

open access: yesFacta Universitatis. Series: Mechanical Engineering, 2017
The paper presents an overall simulation approach to control the noise emission of car engines at a very early stage of the design process where no real prototypes are available.

Towards Resonantly Enhanced Acoustic Phonon-Exchange Magnon Interactions at THz Frequencies

open access: yesMagnetochemistry, 2023
Using valid experimental parameters, we quantify the magnitude of resonantly phonon-driven precession of exchange magnons in freestanding ferromagnetic nickel thin films on their thickness L.

Application to radiation acoustics of the Whitham method for analysing wave phenomena in magnetised plasma

open access: yesKeldysh Institute Preprints, 2023
The exact governing equation of radiative acoustics in radiating grey gas is derived in this work, taking into account the influence of the transverse magnetic field. The radiative MHD is described by three equations of hydrodynamics and two equations of
