[en] The first part of the lecture presents a tutorial review of laser cooling and trapping of atoms and introduces the basic concepts. The second part of the lecture deals with ''Sisyphus cooling'' scheme and its quantum limits and the possibility of achieving a gravitational cavity for neutral atoms. The reader is referred to the general references. (TEC). 15 refs

[en] The problem of information loss in black hole formation and the associated violations of basic laws of physics, such as conservation of energy, causality and unitarity is reviewed. The observational evidence for black holes is reviewed and recent equations of state that allow compact stars with large critical mass to exist are discussed. (TEC). 18 refs

[en] Modern metrology depends increasingly on the accuracy and frequency stability of atomic clocks. Applications of such high-stability oscillators (or clocks) to experiments performed in space are described and estimates of the precision of these experiments are made in terms of clock performance. Methods using time-correlation to cancel localized disturbances in very long signal paths and a proposed space borne four station VLBI system are described. (TEC). 30 refs., 14 figs., 1 tab

[en] If a fermion is travelling through a medium, it can have matter-induced magnetic and electric dipole moments. These contributions conserve chirality, and can be non-vanishing even for a Majorana neutrino. Several implications for neutrino physics are discussed. (author). 21 refs., 1 fig

[en] This paper presents a three-axis superconducting gravity gradiometer and a test using a 1500 Kg lead (Pb) pendulum to produce a time-varying field. The results represent an improvement of an order of magnitude over the best existing limit at λ=1.5 m. (TEC). 8 refs., 2 figs., 1 tab

[en] The spin dependent correlation in the Eotvos data has been reproduced elsewhere. While the Eotvos correlation may be due to an experimental error, it can no longer be considered an experimental artifact. If the effect is an experimental error, that same error exists in other experiments and its origin remains unknown. It is possible that the effect is not an error and does in fact represent new physics. (authors). 4 refs., 3 figs

[en] This paper considers the singularity problem in general relativity with a special reference to those forming in gravitational collapse. The relevance of recent results on collapse models involving perfect fluid, dust and imploding radiations shells is examined in connection with the fundamental problem of cosmic censorship.
