High‐Entropy Magnetism of Murunskite

open access: yesAdvanced Functional Materials, EarlyView.
The study of murunskite (K2FeCu3S4) reveals that its magnetic and orbital order emerges in a simple I4/mmm crystal structure with complete disorder in the transition metal positions. Mixed‐valence Fe ions randomly occupy 1/4 of the tetrahedral sites, with the remaining 3/4 being filled by non‐magnetic Cu+ ions.

The theory of nuclear matter

Advances in Physics, 1961
Abstract This article is an account of the present position of theories of nuclear matter initiated some years ago mainly by Jastrow and Brueckner. Section 1 introduces the basic ideas. Section 2 discusses the variational approach. Section 3 develops methods involving partial summations in perturbation theory.

Theories of Nuclear Proliferation [PDF]

open access: possibleThe Nonproliferation Review, 2006
Traditionally, American thinking on proliferation—whether by scholars or practitioners—has been dominated by the realist camp. According to this view, nuclear weapons are very valuable to states, so only strong supply-side control measures can stop the world's natural tendency toward rampant proliferation. However, realist intuitions have proven a very
