- In physics,
dephasing is a
mechanism that
recovers classical behaviour from a
quantum system. It
refers to the ways in
which coherence caused by perturbation...

leads to an
irreversible loss of magnetisation. But the
inhomogeneous dephasing can be
removed by
applying a 180°
inversion pulse that
inverts the magnetisation...
- [citation needed] A Hahn echo
decay experiment can be used to
measure the
dephasing time, as
shown in the animation. The size of the echo is
recorded for...

transverse relaxation time T2 (for NMR and MRI technology, also
called the
dephasing time),
typically range between nanoseconds and
seconds at low temperature...
- the spins,
allowing the
spins to
dephase and
rephase when required.
After an
excitation pulse, the
spins are
dephased, no

produced because the...
- po****tion can be
broadly classified as spin-flip
scattering and spin
dephasing. Spin-flip
scattering is a
process inside a
solid that does not conserve...
-
polarization dephases typically on a sub-100 fs time-scale in case of
nonresonant excitation due to ultra-fast Coulomb- and phonon-scattering. The
dephasing of...

magnetic resonance experiments, this "relaxation" dominates. This
results in
dephasing. However,
decoherence because of
magnetic field inhomogeneity is not a...

After an
