# effective hamiltonian in a sentence

- The appropriate two-band
*effective Hamiltonian* is - The dynamics of an atom above the atomic mirror is controlled by the
*effective Hamiltonian*, - The Hamiltonian for a linear chain of finite length is an example of an
*effective Hamiltonian*. - In a formal way it is possible to define an
*effective Hamiltonian* that gives exactly the low-lying energy states and wavefunctions. - These methods do not share the shortcomings of the previously used "'
*Effective Hamiltonian* formalisms "'applied to cases warranting a multireference description. - It's difficult to find
*effective hamiltonian* in a sentence. - If we find a transformation U _ { a'a } that puts the
*effective hamiltonian* in flavor basis ( " h " eff ) " ab " in the diagonal form - As a result, one obtains in the rotated basis an
*effective Hamiltonian* matrix eigenvalue problem in which the dependence on cutoff \ Lambda may manifest itself only in the explicit dependence of matrix elements of the new H _ { \ rm eff }. - From a general model-independent point of view, neutrinos oscillate because the
*effective hamiltonian* describing their propagation is not diagonal in flavor space and has a non-degenerate spectrum, in other words, the eigenstates of the hamiltonian are linear superpositions of the flavor eigenstates of the weak interaction and there are at least two different eigenvalues. - The two features of similarity that ( 1 ) the \ Lambda-dependence becomes explicit before one tackles the problem of solving the eigenvalue problem for H _ { \ rm eff } and ( 2 ) the
*effective Hamiltonian* with small energy bandwidth may not depend on the eigenvalues one tries to find, allow one to discover in advance the required counterterms to the diverging cutoff dependence.
