Bath Engineering Enhanced Quantum Critical Engines
Entropy, 2022 Driving a quantum system across quantum critical points leads to non-adiabatic excitations in the system. This in turn may adversely affect the functioning of a quantum machine which uses a quantum critical substance as its working medium. Here we propose a bath-engineered quantum engine (BEQE), in which we use the Kibble–Zurek mechanism and critical ...

A Feshbach engine in the Thomas-Fermi regime [PDF]
, 2020 Bose-Einstein condensates can be used to produce work by tuning the strength of the interparticle interactions with the help of Feshbach resonances. In inhomogeneous potentials, these interaction ramps change the volume of the trapped gas allowing one to

Increasing exhaust temperature to enable after-treatment operation on a two-stage turbo-charged medium speed marine diesel engine [PDF]
, 2018 Nitrogen-oxides (NOx) are becoming more and more regulated. In heavy duty, medium speed engines these emission limits are also being reduced steadily: Selective catalytic reduction is a proven technology which allows to reduce NOx emission with very high
