Electron-positron pair production in space- or time
... The creation of electron-positron pairs from the vacuum by an external uniform electric field in spacetime was first studied by Sauter [1] as a quantum tunneling process. Heisenberg and Euler [2] extended his result by calculating an effective Lagrangian from the Dirac theory for electrons in a cons ...

Quantum cryptography
... • Many “protocols” have been developed for QKD each of which use nonorthogonal basis sets – E.g. BB84 which uses (H,V) and (+45,-45) polarization states of light – “Send and measure” with some classical communication resources – Final steps consist of a “classical” error correction and privacy ampli ...

strong magnetic field
... The vacuum in strong magnetic field Ingredients needed for possible superconductivity: A. Presence of electric charges? Yes, we have them: there are virtual particles which may potentially become “real” (= pop up from the vacuum) and make the vacuum (super)conducting. B. Reduction to 1+1 dimensions ...

Effective Field Theories for Topological states of Matter
... There are, however, states with the same symmetry properties, which nevertheless are distinct in a way that I will now describe. Two states are defined to be in the same universality class if one can be obtained from the other by quasi-adiabatically changing the parameters of the Hamiltonian without ...
