Review:
Eric Opdam, Valerio Toledano Laredo: On Harish-Chandra’s Isomorphism [arXiv:2412.17525 ]
The quantum of magnetic flux is
ϕ 0 = h e
\phi_0
\;=\;
\frac{h}{e}
where
In SI units this is approximately
ϕ 0 ≡ h e ∼ 6.626 × 10 − 34 J s 1.602 × 10 − 19 C ∼ 4.136 × 10 − 15 J s C = 4.136 × 10 − 15 T m 2 ,
\phi_0
\;\equiv\;
\frac{h}{e}
\;\sim\;
\frac
{6.626 \times 10^{-34} \, J s}
{1.602 \times 10^{-19} \, C}
\;\sim\;
4.136 \times 10^{-15} \, \frac{J s}{C}
\;=\;
4.136 \times 10^{-15} \, T m^2
\,,
where in the last step we used that
one Joule is one Newton meter
and one Tesla is one Newton second per Coulomb meter
T ≔ N s C m .
T

\frac
