Characterization of laboratory and real driving emissions of individual Euro 6 light-duty vehicles – Fresh particles and secondary aerosol formation
(2019-12-01)
- article
Emissions from passenger cars are one of major sources that deteriorate urban air quality. This study presents characterization of real-drive emissions from three Euro 6 emission level passenger cars (two gasoline and one ...
Magnetic non-contact friction from domain wall dynamics actuated by oscillatory mechanical motion
(2019-08-13)
- article
Magnetic friction is a form of non-contact friction arising from the dissipation of energy in a magnet due to spin reorientation in a magnetic field. In this paper, we study magnetic friction in the context of micromagnetics, ...
Hybridized plasmon modes in a system of metal thin film-nanodisk array
(2019-09-21)
- article
Controlling the hybridization is a very powerful tool to manipulate the modes in a single nanostructure. We investigate the hybridization between localized and propagating surface plasmons in a nanostructure system where ...
Real-time characterization of spectral instabilities in a mode-locked fibre laser exhibiting soliton-similariton dynamics
(2019-09-27)
- article
The study of dissipative solitons in mode-locked lasers reveals a rich landscape of interaction dynamics resulting from the interplay of nonlinearity, dispersion and dissipation. Here, we characterize a range of instabilities ...
Dynamic Enhancement of Nitric Oxide Radioluminescence with Nitrogen Purge
(2019-09-25)
- article
Remote detection of alpha radiation is commonly realised by collecting the light, the radioluminescence, that is produced when alpha particles are stopped in air. Radioluminescence of nitric oxide (NO) is primarily emitted ...
Analytical computation of the demagnetizing energy of thin-film domain walls
(2019-09-25)
- article
Due to its nonlocal nature, calculating the demagnetizing field remains the biggest challenge in understanding domain structures in ferromagnetic materials. Analytical descriptions of demagnetizing effects typically ...
Fundamental gaps of quantum dots on the cheap
(2019-03-25)
- article
We show that the fundamental gaps of quantum dots can be accurately estimated at the computational effort of a standard ground-state calculation supplemented with a non-self-consistent step of negligible cost, all performed ...
Numerical simulation of Kerr nonlinear systems; analyzing non-classical dynamics
(2019-10-01)
- article
We simulate coherent driven free dissipative Kerr nonlinear system numerically using Euler’s method by solving Heisenberg equation of motion and time evolving block decimation (TEBD) algorithm, and demonstrate how the ...
Normal and Anomalous Diffusion in Soft Lorentz Gases
(2019-02-14)
- article
Motivated by electronic transport in graphenelike structures, we study the diffusion of a classical point particle in Fermi potentials situated on a triangular lattice. We call this system a soft Lorentz gas, as the hard ...
Quantum corrections to a spin-orbit coupled Bose-Einstein Condensate
(2019-08-22)
- article
We study systematically the quantum corrections to a weakly interacting Bose-Einstein condensate with spin-orbit coupling. We show that quantum fluctuations, enhanced by the spin-orbit coupling, modify quantitatively the ...
