On the experiment-friendly formulation of quantum backflow [PDF]

open access: yesQuantum, 2021
In its standard formulation, quantum backflow is a classically impossible phenomenon in which a free quantum particle in a positive-momentum state exhibits a negative probability current. Recently, Miller et al. [Quantum 5, 379 (2021)] have put forward a

Consequence of Blowby Flow and Idling Time on Oil Consumption and Particulate Emissions in Gasoline Engine

open access: yesEnergies, 2022
Pollutant emission standards and, in particular, those concerning particles from an internal combustion engine (ICE) are becoming increasingly restrictive.

Slip Backflow of Polymers in Elastic Fractures for Subsurface Heat Recovery

open access: yesEnergies, 2023
This research delves into the complexities of backflow phenomena in finite-length and flat-walled fractures with elastic walls, specifically focusing on power-law fluids, whose shear-thinning behavior distinguishes them from Newtonian fluids.

Electron hydrodynamics dilemma: whirlpools or no whirlpools [PDF]

open access: yes, 2016
In highly viscous electron systems such as, for example, high quality graphene above liquid nitrogen temperature, a linear response to applied electric current becomes essentially nonlocal, which can give rise to a number of new and counterintuitive ...

Impact of fractures on convective-mixing characteristics of carbon dioxide in saline aquifers

open access: yes工程科学学报
Fractures serve as the main channels for rapid CO2 diffusion and escape during sequestration in saline aquifers. While existing studies have focused on how fracture characteristics and chemical reactions affect CO2 convective mixing, the specific ...

Backflow Correlations for the Electron Gas and Metallic Hydrogen

open access: yes, 2003
We justify and evaluate backflow-threebody wavefunctions for a two component system of electrons and protons. Based on the generalized Feynman-Kacs formula, many-body perturbation theory, and band structure calculations, we analyze the use and the ...

Experimental observation of weak non-Markovianity [PDF]

open access: yes, 2015
Non-Markovianity has recently attracted large interest due to significant advances in its characterization and its exploitation for quantum information processing. However, up to now, only non-Markovian regimes featuring environment to system backflow of

Analytic Examples, Measurement Models and Classical Limit of Quantum Backflow

open access: yes, 2012
We investigate the backflow effect in elementary quantum mechanics - the phenomenon in which a state consisting entirely of positive momenta may have negative current and the probability flows in the opposite direction to the momentum.

Backflow reduction in local injection therapy with gelatin formulations

open access: yesDrug Delivery
The local injection of therapeutic drugs, including cells, oncolytic viruses and nucleic acids, into different organs is an administrative route used to achieve high drug exposure at the site of action.

Numerical Analysis of The Effect of Hydrodynamics and Operating Conditions on Biodiesel Synthesis in a Rotor-Stator Spinning Disk Reactor

open access: yesChemical and Process Engineering, 2017
A rotor-stator spinning disk reactor for intensified biodiesel synthesis is described and numerically simulated in the present research. The reactor consists of two flat disks, located coaxially and parallel to each other with a gap ranging from 0.1 mm ...
