On 16 June 2004, a joint scientific session of the Physical Sciences Division of the Russian Academy of Sciences and the Joint Physical Society of the Russian Federation was held in the Conference Hall of the P L Kapitza Institute for Physical Problems, Russian Academy of Sciences, to honor the 110th birthday of P L Kapitza and the 70th anniversary of the host institute. The following reports were presented at the session:
(1) Andreev A F (P L Kapitza Institute for Physical Problems, RAS, Moscow) ’Quantum crystals’;
(2) Dmitriev V V (P L Kapitza Institute for Physical Problems, RAS, Moscow) ’Spin superfluidity in ³He’;
(3) Lebedev V V (L D Landau Institute of Solid State Physics, RAS, Chernogolovka, Moscow Region) ’Theory of weak crystallization’;
(4) Sosin S S, Prozorova L A, Smirnov A I (P L Kapitza Institute for Physical Problems, RAS, Moscow) ’New magnetic states in crystals’.
Abridged versions of reports 2 and 4 are given below.
