“…The pressure dependence of anisotropy constant was measured experimentally [2]. However, to our knowledge, the data on the pressure dependence of exchange parameter are absent, although it is supposed to be considerable [19]. There are also few experimental data on the ground-state magnetization near QPT.…”

“…A number of approximate methods were applied to study the transverse-field Ising model [8][9][10][11][12][13][14][15][16] at d > 1 and the Heisenberg model with easy-axis anisotropy [17][18][19][20][21]. However, all these methods (except for numerical ones) are applicable only not too close to QPT.…”

The systems exhibiting quantum phase transitions (QPT) are investigated within the Ising model in the transverse field and Heisenberg model with easyplane single-site anisotropy. Near QPT a correspondence between parameters of these models and of quantum φ 4 model is established. A scaling analysis is performed for the ground-state properties. The influence of the external longitudinal magnetic field on the ground-state properties is investigated, and the corresponding magnetic susceptibility is calculated. Finite-temperature properties are considered with the use of the scaling analysis for the effective classical model proposed by Sachdev. Analytical results for the ordering temperature and temperature dependences of the magnetization and energy gap are obtained in the case of a small ground-state moment. The forms of dependences of observable quantities on the bare splitting (or magnetic field) and renormalized splitting turn out to be different. A comparison with numerical calculations and experimental data on systems demonstrating magnetic and structural transitions (e.g., into singlet state) is performed.

“…Lines at frequencies vL + ( 2) + mt-i(CH4) were found in all combinations and in all orders detectable from CH4 and H2 gases mixed together in one cell, or contained in separate cells placed in series so that one laser pulse excited both gases. General theories of stimulated Raman emission have been worked out by Shen (298) and by Lugovai (220), while intensity distributions and thresholds of stimulated Raman lines have been investigated by Maier (223), Zubova, et al (363), and Zubov, Sushchinskii, and Shuvalov (362).…”
