New developments of microscopic nonlocal response theory

A new derivation of macroscopic Maxwell eqs. has been made with a more general form than the conventional ones via a new logic, i.e., the application of long wavelength approximation to the microscopic nonlocal response theory. The most significant aspect is its single susceptibility framework, which represents all the effects of electric and magnetic polarizations including their chirality induced interference effect. This theory is free from the problems of the conventional scheme, i.e., the lack of "uniqueness in the definition of electric and magnetic polarizations" and "the logical consistency with microscopic response theory". A new definition is proposed about magnetic susceptibility from a logical ground. The result is summarized in the form of a book including all the theoretical details, to be published from Springer Verlag in September 2010.
