Quantum
effects in Biomorphism and self assembly.
(OVERVIEW)

|
Under
certain conditions, nano-aggregates of inorganic crystals precipitating
in water solutions, are self-organized to form structures at the
micro/ nano scale that remarkably resemble living micro organisms,
like microfossils and leaves of plants. These structures are known
as "BIOMORPHS".We demonstrated that precipitating biomorphs
and scaling of CaCO3 in water flow surfaces,
is the outcome of quantum interactions between quantum ensembles
of molecular rotors of water that rotate coherently under the action
of an external magnetic field.
Indeed, under external magnetic field, CaCO3
in water solution will precipitate as aragonite than calcite, (the
crystallized state at zero external magnetic field), despite that
the zero field ground electronic state of aragonite is placed higher
than of calcite by 28 eV. Recent experimental and theoretical results
begin to elucidate the process through the amplification of a vacuum
state magnetic fluctuation, which can exchange its energy with the
angular momentum of a single water molecular rotor for a short period
of time. The system is thus driven to a new thermodynamic state
of higher free energy than the state at zero magnetic field. In
the present work, is indicated that the nanocrystalization of CaCO3
precipitants in water solution can probe the interactions between
the electromagnetic field and the matter. At low external magnetic
field, the formation of aragonite is taking place when a vacuum
state electromagnetic mode is trapped, amplified and sustained in
a coherent (collective) antisymmetric state, which is created by
an ensemble of individual molecular rotors, which are excited coherently
by the external magnetic field. The amplified magnetic mode will
not decay to the ground symmetric state of the ensemble of water
molecular rotors due to the forbidden nature of transition between
the antisymmetric and the symmetric state that gives different flower
like biomorpic structure. The ensemble of water molecular rotors
is then driven to a higher free-energy state for a longer period
of time, allowing thus the CaCO3 precipitants
to be crystallized as aragonite. Furthermore, the existence of the
coherent antisymmetric state, elucidate the memory effects observed
previously in water solutions.
