Description
When embedded in a suitable environment, atoms, molecules and
nano-structures can have finite lifetime. Non-hermitian (NH) quantum
mechanics (QM) is particularly suitable to describe these open systems,
mainly because the discrete eigenstates of the NH Hamiltonian
(resonances) provide not only the lifetime of the system but also the
probability to decay into the different open channels. Resonances
appear in most disciplines of science. NHQM aids in discovering fundamental
new phenomena which are hard to discover or explain by other
means. One such exciting phenomenon we have recently discovered show that
for open systems an asymmetrical dynamical behavior is obtained
by an arbitrarily slow variation of potential parameters. This means that
different initial states will end up in the same final state.
We claim that this dynamical asymmetrical decay process is a novel mechansim
to control pathways between different states for a variety
of physical and bio-chemical systems.
