momentum and heat flux measurements in the exhaust of vasimr
... important factor in determining the overall system efficiency. In VASIMR, this “frozen flow loss” is appreciable when at high thrust, but negligible at high Isp. The loss applies to other electric thrusters as well. If some of this energy could be recovered through recombination processes, and re-in ...

Chapter 5 Work and Energy conclusion
... Chapter 6 is about the COLLISION of TWO masses. To understand the interaction, both masses must be considered. Newton's 3rd Law plays a very important part. Collisions involve two new concepts: Impulse and Momentum. Impulse concept leads to the Momentum definition. Also applied to two (or more) mass ...

Comparison of y-scaling for Electrons and Hadrons
... In-medium elastic cross sections are known from free space scattering, with known off-shell effects. The number of one-and-only-one collisions can be computed with the eikonal Glauber model, which depends upon in-medium total beam-nucleon cross sections. Trivial for electrons. Copy the lessons learn ...

Resonant tunnelling through a single level with non-collinear magnetizations
... Transport of spin-polarized electrons through quantum dots coupled to ferromagnetic leads is currently of interest due to possible applications in magnetoelectronic and spintronic devices [1–3]. This applies especially to spin valve structures, where the transition from parallel to antiparallel magn ...

Quantum vacuum thruster
A quantum vacuum plasma thruster (or Q-thruster) is a proposed type of spacecraft thruster that would work in part by acting on the virtual particles produced by quantum vacuum fluctuations. This was proposed as a possible model for an engine that could produce thrust without carrying its own propellant. Some physicists working with microwave resonant cavity thrusters think that they might be the first examples of such an engine.
