quantum dynamical evolutionsThe time variant power series expansion for the expectation value of a given quantum dynamical operator is well-known and well-investigated issue in quantum dynamics. However, depending on the operator and Hamiltonian singularities this expansion either may not exist or may ...
The time dependence of the wave function gives rise to time dependence of the expectation value of observables. We have been exploring the difficulties that advanced undergraduate and graduate students have with time dependence of expectation values in quantum mechanics. We have developed and ...
expectation value Also found in:Dictionary,Thesaurus,Financial,Acronyms. [‚ek‚spek′tā·shən ‚val·yü] (quantum mechanics) The average of the results of a large number of measurements of a quantity made on a system in a given state; in case the measurement disturbs the state, ...
In measuring the x component of angular momentum of a state, by using the expectation value calculation of Lx, i got i/3 h bar - i/3 h bar, does this means that the probability of h bar is i/3 and the probability of 0 h bar is 0 and the probability of -h bar is i/3...

For an unbounded quantum mechanical observable A , the expectation value 〈A〉 f and the mean square deviation Δ f A cannot be denned for all (pure) states f by 〈A〉 f = ( f,Af ) and ( Δ f A ) 2 = ( f,A 2 f )-( f,Af ) 2 , respectively. More general definitions ...
Expectation Expectation value Quantum and general physics Quantum basics Value Wave function Wave functions In summary: I understand that the integral is supposed to be$$ int( x * e^(-2*a ( (m*x^2 / hbar) ) dx) = x * A^(-2) - int( A^(-2) * 2 * x dx) = x * A^(-2...
