Single-atom heat machines enabled by energy quantization [PDF]

open access: yes, 2018
Quantization of energy is a quintessential characteristic of quantum systems. Here we analyze its effects on the operation of Otto cycle heat machines and show that energy quantization alone may alter and increase machine performance in terms of output ...

General working features of axially compressive members revealed by structural stressing state theory

open access: yesCase Studies in Construction Materials, 2022
This paper reveals the general working law of compressive members by the stressing state modeling and analysis of their simulative response date. Firstly, the finite element simulation of compressive members with various slenderness ratios obtains the ...

Persistent currents in multicomponent Tomonaga-Luttinger liquid: application to mesoscopic semiconductor ring with spin-orbit interaction

open access: yes, 2004
We study persistent currents in semiconductor ballistic rings with spin-orbit Rashba interaction. We use as a working model the multicomponent Tomonaga-Luttinger liquid which arises due to the nonparabolic dispersion relations of electrons in the rings ...
