Non-Markovian stochastic Liouville equation and anomalous relaxation kinetics
The kinetics of phase and population relaxation in quantum systems induced by
noise with anomalously slowly decaying correlation function P (t) ~ (wt)^{-
alpha}, where 0 < alpha < 1 is analyzed within continuous time random walk
approach. The relaxation kinetics is shown to be anomalously slow. Moreover for
alpha < 1 in the limit of short characteristic time of fluctuations w^{-1} the
kinetics is independent of w. As alpha \to 1 the relaxation regime changes from
the static limit to fluctuation narrowing. Simple analytical expressions are
obtained describing the specific features of the kinetics.Comment: 7 pages, 2 figure

Key factors of efficient organization management
Issues of efficiency of organization management are examined in the article. Aggressive competition between companies; whatβs the difference between manager and leader; who is a leader; personal qualities of strong charismatic leaders etc. Particular attention is paid to the question of possibility to become a leader or to be born a leader.Π ΡΡΠ°ΡΡΠ΅ ΡΠ°ΡΡΠΌΠΎΡΡΠ΅Π½Ρ ΠΎΡΠ½ΠΎΠ²Π½ΡΠ΅ ΡΠ΅ΡΡΡ Π½Π°ΡΡΠΎΡΡΠ΅Π³ΠΎ Π»ΠΈΠ΄Π΅ΡΠ°, Π·Π°ΡΡΠΎΠ½ΡΡΠ° ΡΠ΅ΠΌΠ° ΡΠ°Π·Π»ΠΈΡΠΈΡ ΠΌΠ΅ΠΆΠ΄Ρ Π»ΠΈΠ΄Π΅ΡΠΎΠΌ ΠΈ ΠΌΠ΅Π½Π΅Π΄ΠΆΠ΅ΡΠΎΠΌ, Π° ΡΠ°ΠΊΠΆΠ΅ ΠΎΡΠ²Π΅ΡΡΠ½ Π²ΠΎΠΏΡΠΎΡ ΠΎ ΡΠΎΠΌ, ΠΌΠΎΠΆΠ½ΠΎ Π»ΠΈ ΡΡΠ°ΡΡ Π»ΠΈΠ΄Π΅ΡΠΎΠΌ
