Comment on “Non-representative Quantum Mechanical Weak Values”
... where g is the (time-integrated) coupling constant, S is the operator whose weak value we wish to measure and PM is the conjugate momentum to the measuring device. Svensson’s procedure for producing a weak measurement entails taking the coupling constant g to the limit g → 0. This approach is differ ...

In this approximation, energy of a configuration is just sum of Ei No reference to projections of li or to spins degeneracy If we go beyond the central-field approximation some of the degeneracies will be lifted Also spin-orbit (ls) interaction lifts some degeneracies In general, both effects nee ...

Extremal eigenvalues of local Hamiltonians
... Theorem 1 are based on the use of a correspondence between local quantum Hamiltonians and lowdegree polynomials, which allows us to apply classical approximation algorithms for constraint satisfaction problems. This correspondence uses a qubit 2design [5, 13] to convert arbitrary qubit Hamiltonians ...
