WebThe original Born-Fock adiabatic theorem does not work after the frequency passes through zero. However, its generalization is found: the initial Fock state becomes a wide superposition of many instantaneous Fock states, whose weights do not depend on time in the new adiabatic regime. http://qserver.usc.edu/wp-content/uploads/2013/07/pra710123312005.pdf
WebAug 24, 2024 · The adiabatic theorem [ 1] asserts that a system prepared in a nondegenerate eigenstate will remain in that instantaneous eigenstate if the system’s Hamiltonian changes sufficiently slow, even though the eigenvalue could change.
WebDiabatic states can be defined in an endless number of ways, but only one adiabatic surface exists. In that respect, the term “nonadiabatic” is also used to refer to all possible diabatic surfaces. However, diabatic states are generally chosen so that the nonadiabatic electronic couplings in Equation 6.2.14 and 6.2.15 are zero.
The adiabatic theorem is a concept in quantum mechanics. Its original form, due to Max Born and Vladimir Fock (1928), was stated as follows: A physical system remains in its instantaneous eigenstate if a given perturbation is acting on it slowly enough and if there is a gap between the eigenvalue and the rest … See more At some initial time $${\displaystyle t_{0}}$$ a quantum-mechanical system has an energy given by the Hamiltonian $${\displaystyle {\hat {H}}(t_{0})}$$; the system is in an eigenstate of For a truly adiabatic … See more Under a slowly changing Hamiltonian $${\displaystyle H(t)}$$ with instantaneous eigenstates $${\displaystyle n(t)\rangle }$$ and corresponding … See more We will now pursue a more rigorous analysis.
