Small bodies in Earth-like orbits, the Arjunas, are good targets for scientific exploration, and space mining or situ resource utilization (ISRU) trials as they enable low-cost missions. The subset of these objects that experience recurrent temporarily captured flyby orbiter episodes among best ranked terms accessibility. Only a handful known to have engaged such dynamical behavior. Finding characterizing more them may help expand commercial research activities over next few decades....
Observations of binary stars containing an accreting black hole or neutron star often show x-ray emission extending to high energies (>10 kilo--electron volts), which is ascribed accretion disk corona energetic particles akin those seen in the solar corona. Despite their ubiquity, physical conditions coronae remain poorly constrained. Using simultaneous infrared, optical, x-ray, and radio observations Galactic system V404 Cygni, showing a rapid synchrotron cooling event its 2015 outburst, we...
Events such as GRB130606A at z=5.91, offer an exciting new window into pre-galactic metal enrichment in these very high redshift host galaxies. We study the environment and galaxy of GRB 130606A, a high-z event, context population GRBs. have obtained multiwavelength observations from radio to gamma-ray, concentrating particularly on X-ray evolution well optical photometric spectroscopic data analysis. With initial Lorentz bulk factor range Γ_0 ~ 65-220, afterglow can be explained by...
The possibility of efficiently converting heat into work at the microscale has triggered an intense research effort to understand quantum engines, driven by hope superiority over classical counterparts. In this work, we introduce a model featuring atom-doped optical cavity propelling piston through radiation pressure. model, based on Jaynes-Cummings Hamiltonian electrodynamics, demonstrates generation mechanical thermal energy injection. We establish equivalence expansion with Alicki's...

An intriguing phenomenon in non-equilibrium quantum thermodynamics is the asymmetry of thermal processes. Relaxation to equilibrium most important dissipative process, being a key concept for design heat engines and refrigerators, contributing study foundational questions thermodynamics, relevant computing through process algorithmic cooling. Despite importance this kind processes, their dynamics are far from understood. We show that free relaxation follows intrinsically different paths...
Light can be squeezed by reducing the quantum uncertainty of electric field for some phases. We show how to use this purely-quantum effect extract net mechanical work from radiation pressure in a simple photon engine. Along way, we demonstrate that standard definition systems is not appropriate context, as it does capture energy leaked these degrees freedom. results design an Otto engine able produce squeezing baths, absence thermal gradient. Interestingly, while extraction generally...
Context. Small bodies in Earth-like orbits, the Arjunas, are good targets for scientific exploration and mining studies as they enable low-cost missions. The subset of such objects that experience recurrent temporarily captured flyby or orbiter events, also called mini-moon episodes, among best ranked terms accessibility. Only a handful known to have engaged dynamical behavior. Finding characterizing more them may help expand commercial research activities space over next few decades....
Abstract In this article, we present a simple, inexpensive, and effective method for measuring the capacitor charge discharge processes using light-emitting diode (LED) light meter of smartphone. We propose simple circuit in which LED’s brightness is linear on capacitor’s voltage, allowing us to use smartphone monitor state accurately. The tested experimentally, giving highly satisfactory results. Its exceptional combination accuracy, minimal requirements, ease setup makes it an excellent...
