García Calderón was a D.Phil. student of Peierls at Oxford, later working at the University of Mexico. His work with Peierls on resonant states led to a joint paper, 'Resonant states and their uses' (Nuclear Physics A, 265, 1976). See Bird of Passage, pp. 329-330. Scientific and publications correspondence, mainly on joint paper. Includes referees' comments.

Continuing work on resonant states.

Proposed experiment to measure the apparent mass of the photon.

Publication of joint paper, 'A model for low-temperature anharmonicity' (Journal of Physics, C11, 1977).

Correspondence in Russian; letters 1984-1986 are addressed to Genia. On various topics in the history of science, principally Gorelik's biography of M.P. Bronstein (Bird of Passage, p. 69).

Nuclear weapons control, density matrix measurement.

History of semi-conductors in 1920s and 1930s.

Controversy on electromigration, theory and publications (arising from Peierls's joint papers with A.K. Das 1973, 1975).

Problems in quantum mechanics.

Detailed correspondence on solitons and lattice thermal conductivity.

Jonah was a student of Peierls at Birmingham later returning to Freetown, Sierra Leone (see Bird of Passage p. 259).
