Interference Oscillations in the Angular Distribution of Laser-Ionized Electrons near Ionization Threshold
(American Physical Society, 2006-04-14)
We analyze the two-dimensional momentum distribution of electrons ionized by few-cycle laser pulses in the transition regime from multiphoton absorption to tunneling by solving the time-dependent Schrodinger equation and ...
Heat capacity in doped graphene under magnetic fields: the role of spin splitting
(IOP Publishing, 2020-08-14)
We study the electronic heat capacity in doped graphene under magnetic fields. The partition function is calculated considering only the thermal excitations in the last occupied energy levels. Due to the large energy ...
Power Oscillation Damping Improvement by adding Multiple Wind Farms to Wide-Area Coordinating Controls
(Institute of Electrical and Electronics Engineers, 2014)
Complex Dissipating Energy Flow Method for Forced Oscillation Source Location
(Institute of Electrical and Electronics Engineers, 2022)
Spin heat engine coupled to a harmonic oscillator flywheel
(American Physical Society, 2019-08-22)
We realize a heat engine using a single-electron spin as a working medium. The spin pertains to the valence electron of a trapped 40 Ca + ion, and heat reservoirs are emulated by controlling the spin polarization via optical ...
Transport and Spectroscopy in Conjugated Molecules: Two Properties and a Single Rationale
(American Chemical Society, 2020-05)
In the context of electron dynamics simulations, when the charge density of a molecule is subject to a perturbation in the form of a short electric field pulse, density fluctuations develop in time. In the absence of ...
Neutrino Oscillations and Decoherence in Short-GRB Progenitors
(IOP Publishing, 2019-02-12)
Neutrinos are produced in cosmic accelerators, like active galactic nuclei, blazars, supernova remnants and gamma-ray bursts (GRBs). On their way to the Earth they experience flavor oscillations. The interactions of the ...
Compensation of laser frequency fluctuations and phase noise in 16-QAM coherent receivers
(Institute of Electrical and Electronics Engineers, 2013-01-18)
Frequency fluctuations caused by mechanical vibrations, power supply noise, and other mechanisms are detrimental to the phase estimator performance in high speed intradyne coherent optical receivers. In this letter, we ...
Experimental verification of position-dependent angular-momentum selection rules for absorption of twisted light by a bound electron
(IOP Publishing, 2018-02)
We analyze the multipole excitation of atoms with twisted light, i.e, by a vortex light field that carries orbital angular momentum. A single trapped 40Ca+ ion serves as a localized and positioned probe of the exciting ...
Improving Small-Signal Stability of Power Systems with Significant Converter-Interfaced Generation
(Institute of Electrical and Electronics Engineers, 2020-07-21)
This work presents a hierarchical control strategy to improve the stability of electrical networks with significant converter-interfaced generation (CIG). Due to the lack of inertia of CIG systems, these networks can undergo ...
