constants¶
A few useful physical constants
Note that energy is expressed in units of eV.
-
c
= 299792458¶ [m/s] speed of light
-
e
= 1.602e-19¶ [C] electron charge
-
epsilon0
= 8.854e-12¶ [F/m] vacuum permittivity
-
hbar
= 6.582118989999999e-16¶ [eV*s] reduced Plank constant
-
pauli
= x: [[0, 1], [1, 0]], y: [[0, -1j], [1j, 0]], z: [[1, 0], [0, -1]]¶ Pauli matrices – use the
