COMMENT ON “OSCILLATORY INDIRECT INTERACTION BETWEEN ADSORBED ATOMS - NON-ASYMPTOTIC BEHAVIOR IN TIGHT-BINDING MODELS AT REALlSTIC PARAMETERS” BY K.H. LAU AND W. KOHN

A comment on cultural attributes and fluidity of bisexuality.

Selected aspects of the "essentialist" critiques and reviews in Bisexual and Homosexual Identities: Critical Theoretical Issues (De Cecco & Shively, eds., 1983/1984) of the idea of the bisexual identity are examined from the standpoint of their cross-cultural significance. Examples from recent studies in Melanesia are used to highlight possible areas of exploration for future research in homose...

Discontinuity of the exchange-correlation potential from a density-functional viewpoint.

Comment on "investigation of the correlation potential from Kohn-Sham perturbation theory".

Perturbation theory on the basis of the Kohn-Sham Hamiltonian leads to an implicit density functional for the correlation energy E(c). In this contribution we investigate the corresponding correlation potential v(c). It is shown that for finite systems the v(c) obtained by direct application of the optimized potential method diverges in the asymptotic region. The presence of unoccupied states, ...

Comments: Pricing and Cost of Electronics Journals

To be considered for publication in the Comments section, letters should be relatively short—generally fewer than 1000 words—and should be sent to the journal ofŽces at the address appearing inside the front cover. The editors will choose which letters will be published. All published letters will be subject to editing for style and length. In what follows, Joop Dirkmaat of Elsevier Science and...
