... Null cosmologies: Φ = Φ(x+ ) . No nonzero contraction so the mass term vanishes i.e. m2 (Φ) = 0. Similar story for gauge theory using lightcone gauge for convenience. Suppressing many details, but briefly, cubic/quartic interaction terms: multiplied by powers of gY M = eΦ/2 , unimportant near eΦ → 0 ...

Charge dynamics and spin blockade in a hybrid double quantum dot
... Electron spin qubits in silicon, whether in quantum dots or in donor atoms, have long been considered attractive qubits for the implementation of a quantum computer because of silicon’s “semiconductor vacuum” character and its compatibility with the microelectronics industry. While donor electron sp ...

Lecture 12 Atomic structure
... In addition to nuclear binding potential, there is a further Coulomb interaction between electrons. As we have seen with helium, this contribution can have important consequences on spectra and spin structure of wavefunction. However, electron-electron interaction makes problem “many-body” in charac ...

... Fock states, definition: So far, we have concentrated on introducing operators for the vector potential and thus the electric field. We have found that the quantized free electromagnetic field is an infinite collection of uncoupled harmonic oscillators, each of which is described by a Hamiltonian Ĥλ = ...
