Source document Physical Review B. Vol. 95, no. 5 (2017), pp. [1-2]. - Maryland : American Physical Society, 2017 Keywords quasi-two-dimensional quantum antiferromagnet square lattice two-dimensional lattice space magnetic anisotropy Language English Country United States of America systematics 53 Annotation Theoretical and experimental studies of a quasi-two-dimensional quantum antiferromagnet Cu(en)(H2O)(2)SO4 (en = C2H8N2) were performed. ab initio calculations of exchange interactions confirmed that the system represents a realization of a spatially anisotropic zigzag square lattice. Corresponding quantum Monte Carlo calculations of thermodynamic quantities were realized and the results were applied in the analysis of experimental susceptibility, magnetization, and specific heat studied at temperatures ranging from nominally 300 mK up to 8 K and magnetic fields up to 14 T. The analysis of experimental results provided the estimates of intralayer exchange couplings, J/k(B) = 3.5 +/- 0.2 K and J (1) = 0.35 J. Theoretical analysis of spin symmetries in Cu( en)( H2O) 2SO4 structure predicted the presence of symmetric exchange anisotropies (out- of plane and in-plane spin anisotropy) and a spin-flop transition within the easy plane induced by the magnetic field applied along the easy axis. Isothermal magnetization measurements indicated the expected transition in the field 200 mT applied along the b axis which was finally identified as the easy axis lying within the easy plane bc. Magnetic phase diagrams with saturation fields about 6.5 T show nearly identical behavior in all studied directions. Differences appear only in weak magnetic fields as a result of the presence of weak exchange anisotropies approximate to 10(-3) J. The present analysis suggests that Cu( en)( H2O) 2SO4 can be a model system for exploring the interplay of quantum fluctuations, exchange anisotropies, and magnetic field in the two-dimensional lattice space.

Vol. 52, no. 10 (2016), art. no. 311, pp. [1-10]. - Berlin : Springer, 2016 Keywords magnetic anisotropy fyzika - physics Language English Country United States of America systematics 53 Annotation © 2016, SIF, Springer-Verlag Berlin Heidelberg.The Buda-Lund hydro model describes an expanding ellipsoidal fireball, and fits the observed elliptic flow and oscillating HBT radii successfully. Due to fluctuations in energy depositions, the fireball shape however fluctuates on an event-by-event basis. The transverse plane asymmetry can be translated into a series of multipole anisotropy coefficients. These anisotropies then result in measurable momentum-space anisotropies, to be measured with respect to their respective symmetry planes. In this paper we detail an extension of the Buda-Lund model to multipole anisotropies and investigate the resulting flow coefficients and oscillations of HBT radii.
