Charge dynamics and spin blockade in a hybrid double quantum dot
... transient measurement impossible in our case. Instead, we use a procedure developed by Petta et al. [42], where the MW excitation is chopped at some frequency 1=τ with a 50% duty cycle while time averaging the signal at the ICT. We define the charge polarization as P ¼ ðPg − Pe Þ, with Pg and Pe the ...

Spin Squeezing on an Atomic Clock Transition.
... Spin squeezing requires a Hamiltonian that is at least quadratic in the spin components, or equivalently, some form of interaction between the particles. While it is possible to use interatomic collisions in a Bose-Einstein condensate (BEC) for that purpose,14,15 these density-dependent interactions ...

The semantics of the canonical commutation relation
... we want to keep the structure VA a Zariski structure (hence ω-stable). In fact, for each particular A we need just a finitely generated subfield of R0 [i]. With the inner product and a formal complex conjugation defined we can also speak of adjoint operators, unitarity and so on. 1.9 The constructio ...

The Hamiltonian and Lagrangian densities

Indeed the Hamiltonian density subsequently derived does transform in the wrong way and its integral over space does not correspond with the Hamiltonian of the classical relativistic particle. The origin of these substitutions can be understood by looking at ...
