Entropic Bounds on Information Backflow. [PDF]
Physical Review Letters, 2021 In the dynamics of open quantum systems, the backflow of information to the reduced system under study has been suggested as the actual physical mechanism inducing memory and thus leading to non-Markovian quantum dynamics. To this aim, the trace-distance

Unbounded quantum backflow in two dimensions [PDF]
Physical Review A, 2022 Quantum backflow refers to the counterintuitive fact that the probability can flow in the direction opposite to the momentum of a quantum particle. This phenomenon has been seen to be small and fragile for one-dimensional systems, in which the maximal ...

Energies, 2021 Particulate emission from internal combustion engines is a complex phenomenon that needs to be understood in order to identify its main factors. To this end, it appears necessary to study the impact of unburned gases, called blow-by gases, which are ...

Mechanism of urosepsis: relationship between intrarenal pressures and pyelovenous backflow
BJU International, 2023 To document the histological changes observed in renal units subjected to elevated intrarenal pressures (IRPs) and postulate the possible mechanisms of infectious complications after ureteroscopy.

Matrix product states with backflow correlations [PDF]
Physical review B, 2022 By taking inspiration from the backflow transformation for correlated systems, we introduce a novel tensor network ansatz which extend the well-established Matrix Product State representation of a quantum-many body wave function.

Hysteresis of Backflow Imprinted in Collimated Jets [PDF]
, 1997 We report two different types of backflow from jets by performing 2D special relativistic hydrodynamical simulations. One is anti-parallel and quasi-straight to the main jet (quasi-straight backflow), and the other is bent path of the backflow (bent ...

Hydrodynamics and sediment transport in Poyang Lake under the effects of wind and backflow
Hydrology Research, 2023 The ecology of the aquatic environment in Poyang Lake, the largest fresh lake in China, is notably impacted by the backflow from the Yangtze River, which conveys a high flux of sediments.

Operator backflow and the classical simulation of quantum transport [PDF]
Physical review B, 2021 Tensor product states have proved extremely powerful for simulating the area-law entangled states of many-body systems, such as the ground states of gapped Hamiltonians in one dimension.

Relativistic quantum backflow [PDF]
Physica Scripta, 2019 In this paper we discuss relativistic quantum backflow. The general theory of relativistic backflow is written down and it is shown that the backflow can be written as a function of a simple parameter which is defined in terms of fundamental constants and the backflow period.

Effects of stable clearances on backflow in the variable-pitch screw vacuum pump
Mechanics & Industry, 2021 Effects of various clearances of variable-pitch screw vacuum pump on gas backflow of internal flow field of the pump cavity is studied. The theoretical tooth surfaces of screw rotor are optimized by radial, normal equidistance modifications, and four ...
