Optimization and stabilization of a kilohertz laser-plasma accelerator
L. Rovige, J. Huijts, I. A. Andriyash +13
Laser plasma acceleration at kilohertz repetition rate has recently been shown to work in two different regimes, with pulse lengths of either 30 fs or 3.5 fs. We now report on a sy…
Vibrational and vibronic structure of isolated point defects: the nitrogen-vacancy center in diamond
Lukas Razinkovas, Marcus W. Doherty, Neil B. Manson +2
We present a theoretical study of vibrational and vibronic properties of a point defect in the dilute limit by means of first-principles density functional theory calculations. As…
Nonrad: Computing Nonradiative Capture Coefficients from First Principles
Mark E. Turiansky, Audrius Alkauskas, Manuel Engel +5
Point defects in semiconductor crystals provide a means for carriers to recombine nonradiatively. This recombination process impacts the performance of devices. We present the Nonr…
Novel ultrafast laser ablation by bibursts in the MHz and GHz pulse repetition rates
Andrius Žemaitis, Mantas Gaidys, Paulius Gečys +2
Here, to the best of our knowledge, for the first time we report the in-depth experimental study of high ultrafast laser ablation efficiency for processing of copper and steel with…
Broadband self-switching of femtosecond pulses in highly nonlinear high index contrast dual-core fibre
M. Longobucco, I. Astrauskas, A. Pugžlys +5
In this paper, we demonstrate a pulse energy-governed nonlinear self-switching of femtosecond pulses at wavelength of 1700 nm in a highly nonlinear high index contrast dual-core fi…
Evolution of the crystal structure and magnetic properties of Sm-doped BiFeO3 ceramics across the phase boundary region
D. V. Karpinsky, A. Pakalniskis, G. Niaura +10
Samarium doped BiFeO3 compounds having nano-size crystallites were prepared by the ethylene glycol assisted sol-gel synthesis method. X-ray diffraction and SEM measurements as well…
Study of star clusters in the M83 galaxy with a convolutional neural network
J. Bialopetravičius, D. Narbutis
We present a study of evolutionary and structural parameters of star cluster candidates in the spiral galaxy M83. For this we use a convolutional neural network trained on mock clu…
Fibonacci terahertz imaging by silicon diffractive optics
Domas Jokubauskis, Linas Minkevičius, Mindaugas Karaliūnas +4
Fibonacci or bifocal terahertz (THz) imaging is demonstrated experimentally employing silicon diffractive zone plate (SDZP) in a continuous wave mode. Images simultaneously recorde…
Negative flow of energy in a mechanical wave
A. Matulis, A. Acus
A classical system, which is analogous to the quantum one with a backflow of probability, is proposed. The system consists of a chain of masses interconnected by springs, as well a…
Unstable delayed feedback control to change sign of coupling strength for weakly coupled limit cycle oscillators
Viktor Novičenko, Irmantas Ratas
Weakly coupled limit cycle oscillators can be reduced into a system of weakly coupled phase models. These phase models are helpful to analyze the synchronization phenomena. For exa…
Intermittent AGN episodes drive outflows with a large spread of observable loading factors
Kastytis Zubovas, Emanuele Nardini
The properties of large-scale galactic outflows, such as their kinetic energy and momentum rates, correlate with the luminosity of the active galactic nucleus (AGN). This is well e…
Entrainment of a network of interacting neurons with minimum stimulating charge
Kestutis Pyragas, Augustinas P. Fedaravičius, Tatjana Pyragienė
Periodic pulse train stimulation is generically used to study the function of the nervous system and to counteract disease-related neuronal activity, e.g., collective periodic neur…
Demonstration of stable long-term operation of a kilohertz laser-plasma accelerator
Lucas Rovige, Julius Huijts, Aline Vernier +10
We report on the stable and continuous operation of a kilohertz laser-plasma accelerator. Electron bunches with 2.6 pC charge and 2.5 MeV peak energy were generated via injection a…
The case for the fundamental - relation
Christopher Marsden, Francesco Shankar, Michele Ginolfi +1
Strong scaling relations between host galaxy properties (such as stellar mass, bulge mass, luminosity, effective radius etc) and their nuclear supermassive black hole's mass point…
Direct and High-Throughput Fabrication of Mie-Resonant Metasurfaces via Single-Pulse Laser Interference
Jonas Berzinš, Simonas Indrišiūnas, Koen van Erve +8
High-index dielectric metasurfaces featuring Mie-type electric and magnetic resonances have been of a great interest in a variety of applications such as imaging, sensing, photovol…
Using reservoir computer to predict and prevent extreme events
Viktoras Pyragas, Kestutis Pyragas
We show that a reservoir computer is an effective tool for model-free prediction of extreme events in deterministic chaotic systems. This prediction allows us to suppress unwanted…
Evolution of dwarf galaxy observable parameters
Eimantas Ledinauskas, Kastytis Zubovas
We present a semi-analytic model of isolated dwarf galaxy evolution and use it to study the build-up of observed correlations between dwarf galaxy properties. We analyse the evolut…
