In lambda type atomic system, the population is transferred from one ground state to another by using counter intuitive sequence of pulses. This process is well known as stimulated Raman adiabatic passage (STIRAP). However in optomechanics the coherent superposition of states are observed between mechanical mode and cavity mode. In both the above cases population is transferred from either one state to another or from mechanical to cavity mode and vice versa.
What is the difference between state exchange/ transfer and population transfer in quantum system?
Dear Anil Chauhan,
If you take a look at our Mallick-Hamburger-Mallick Dbranes String Theory Functor Algebra Calculus say on www.econometricsociety.org/[email protected] in particular (Mallick,Hamburger, Mallick (2016, 2017, 2017, 2017, 2017)) you will find that our spacextime Systems Classification and Systems Integration Quantum spacetime factorisation mechanism and String Matching Genetic Algorithmic Field Theory of AGG'NN Networks in cybernetic systems creates protocols which can relatistically-quantum mechanically using String Higgs-Englert-Bosonic Relativistic Archimedean particle stock and flow transfer population from one state to another or statistical mechanically by using say entropic group homology or from mechanical to cavity mode. This depends on the effect of the particle flows on the system equilibrium in spacetime i.e. for example in what state of thermodynamic equilibrium the system stabilises quantum mechanically. The coherence problem in your transfer paradox can be solved by our M-H-M FAC applied to the Statistical Mechanics of the system. However, this answer somehow anticipates that there is negative entropy states or phases.
