But an engineered and controlled collection, a "quantum many-body system
," arranges all its atoms in a particular pattern, or correlation, to create the lowest overall energy state.
We focus here on the PMF ([W.sub.PMF](r)), which is the average interaction the particles experience due to collisions with each other and with the solvent; hence, it provides important thermodynamic information about a many-body system
. It can be obtained from the colloids' radial distribution functions, g(r), through the relation (15,23):
The GCM is a macroscopic nuclear structure model in the sense that it considers the nucleus as a charged liquid drop with a definite surface, rather than a many-body system
of constituent particles.
For a many-body system
, quantum potential acting on each particle is a function of the positions of all the other particles and thus, in general, doesn't decrease with distance.
The ground state of QCD is best thought of as a many-body system
for which knowledge of both the elementary excitations of the system and their correlations in the ground state are essential components for a physical understanding.
As Vitiello explains, this is related to the model of the brain as a many-body system
. In such a QFF model those states are ordered and at the same time they are states at minimum energy.
Generally, Hamiltonian of a many-body system
with variety of interactions between particles is too difficult to handle.
On one hand, HEE can be used as a perfect probe to study quantum information science [1-3], strongly correlated quantum systems [4-13], and Many-Body Systems
