This edition is a compilation of selected works of Yurii Aleksandrovich Tserkovnikov (1928±2008), an outstanding specialist in statistical mechanics, the method of two-time temperature-dependent Green's functions, plasma physics, and the theory of nonideal Bose gas. Tserkovnikovwas one of the brightest stars in NN Bogoliubov's scientific school. This collection brings together 30 articles reflecting the main fields of YuATserkovnikov's scientific activity overmore than half a century, previously scattered through various journals. They remain scientifically and methodologically relevant. The book is intended for researchers, postgraduates, and senior-year university students in physics and mathematics specializing in statistical mechanics and its applications to condensed matter physics. The list of Yu A Tserkovnikov's published scientific papers is given at the end of the volume. (Yanus-K Publishing LLC: 127411 Moscow, ul. Uchinskaya 1; tel. (7-495) 245-58-92)

H-C NaÈ gerl of Innsbruck University in Austria and his colleagues have for the first time observed three-particle bound quantum states whose existence was predicted theoretically by V I Efimov in 1970 already [Yadernaya Fizika 12 1080 (1970)] Ð in a rare example of the complex three-body problem allowing an exact analytical solution. A universal set of low-energy bound states appears for a system of three identical particles with a strong enough resonant two-body interaction. Interestingly, because of the quantum-mechanical nature of this effect, three-particle states can even exist in the absence of two-particle bound states. The size of the threeparticle system is much less than the absolute scattering length jaj, and the three-particle interactions are universal in character and independent of precisely how two particles interact when close together. The researchers studied in experiment a degenerate gas of caesium atoms held in an optical dipole trap at temperatures between 10 and 250 nK. The scattering length was controlled by a Feshbach resonance and could be varied over a wide range by tuning the external magnetic field. For a < 0, the Efimov states were identified by a sharp increase in atomic recombination losses in the trapÐ presumably due to the three-atom system rapidly decaying from the trimer state to the state involving a deeply bound dimer state plus a free atom. At a temperature of 10 nK, Efimov states appeared when the scattering length reached ÿ850 Bohr radii. Another type of Efimov state appeared for a > 0. In this case, recombination losses are much lower and exhibit in their spectrum a recombination minimum due to the destructive interference of the three-particle system's quantum decay channels. The position of the minimum agrees well with theoretical predictions. For a > 0, Efimov states arise due to Feshbach resonances in collisions between single atoms and dimers and can be interpreted as a threebody generalization to the Feshbach resonance concept.

Magnetism of electrons is usually measured with the aid of so-called atom traps. The precision of measurements is to a large extend limited by the interaction of the electron and its mirror image charge induced by the electron in the electrodes of the trap. It is difficult to account for this interaction. Hans Dehmelt and his colleagues at the University of Washington succeeded in imprisoning 1000 electrons in an atom trap, thus producing a singlecomponent plasma consisting of negative charges only. The resulting droplet with spherical symmetry behaves like a point-like object with a charge and mass 1000 times those of a single electron. By studying such electron balls it is possible to account more accurately for the interaction of electrons with their mirror images. Electron balls may be useful in experimental plasma physics and many offer research areas. Source: Physics News Update, Number 241, physnews@ aip .org.
