Benefits of Open Quantum Systems for Quantum Machine Learning

Advanced Quantum Technologies, EarlyView., 2023
Quantum machine learning (QML), poised to transform data processing, faces challenges from environmental noise and dissipation. While traditional efforts seek to combat these hindrances, this perspective proposes harnessing them for potential advantages. Surprisingly, under certain conditions, noise and dissipation can benefit QML.

Designer Fluorescent Redoxmer Self‐Reports Side Reactions in Nonaqueous Redox Flow Batteries

Batteries &Supercaps, EarlyView.
A dimeric redoxmer, DGL‐N‐CH3, containing two 2,1,3‐benzothiadiazole units, provides ample opportunity for monitoring for nonaqueous flow batteries. Combined spectroscopic and electrochemical analyses revealed a degradation product, NHCH3‐BzNSN, with a unique optical signature (orange fluorescence) distinct from DGL‐N‐CH3 (blue‐green).

A connection between the shallow-water equations and the Euler-Poincaré equations [PDF]

arXiv, 2014
The Euler-Poincar\'e differential (EPDiff) equations and the shallow water (SW) equations share similar wave characteristics. Using the Hamiltonian structure of the SW equations with flat bottom topography, we establish a connection between the EPDiff equations and the SW equations in one and multi-dimensions.

The Curious Concept That Almost Nobody Seemed to Care About at First: Virtual Particles in the Post‐War Period**

Berichte zur Wissenschaftsgeschichte, EarlyView.
Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

Soliton solution of the generalized fifth order Hirota-Satsuma equation coupled with KdV [PDF]

arXiv, 2016
We introduced a fifth-order partial differential equation as a generalization of Hirota-Satsuma coupled with KdV system. This equation is investigated based on tanh method. By applying the suitable independent variable in Hirota-Satsuma equation, we can convert this partial differential equations(PDE) into ordinary differential equations(ODE) .Solving ...
