In this letter, we describe the design of such a tunable spin filter, that exploits the known magnetotransport properties of quantum point contacts. We also explore the different require ...

Wave Function as Geometric Entity
... since defining the composition operation involves some complications. Thus allowed states are depleted inasmuch as wave function behavior under the parallel translation cannot be calculated and appropriately interpreted, and, besides that, the states of the particle ensemble cannot be determined. As ...

Supersymmetry: what? why? when?
... nature is simpler near the uni® cation scale, as described in the previous section. The various masses of superpartners, etc., do not have any special values. But just as coupling strengths change when examined at diVerent distance or energy scales, so do masses. In the supersymmetric case the entir ...

Remarks on quantum gravity models and supersymplectic structures
... In the following we will calculate the Fisher information metric corresponding to a generalized Hitchin `on-shell' Lagrangian prescription. In our case, the parameters of interest in the metric solution are a and a∗, which could indicate the residual effects of supersymmetry given that they survive ...

Strong Electroweak Symmetry Breaking
... answers exist but none has been shown to be true in experiment. One possibility in the Standard Model is that particles obtain mass through spontaneous symmetry breaking at the scale of the electroweak force. Spontaneous symmetry breaking can be understood with a “Mexican hat” depicting a potential ...
