  • Effective conformational search methods for biological macromolecules 
    Çelik, T. (Физика низких температур, 2007)
    The configuration space of many complex physical systems presents a rough energy landscape consisting of tremendous number of local minima separated by high energy barriers. One way to overcome these barriers is to perform ...

    Sati, P.; Pashchenko, V.; Stepanov, A. (2007)
    We study the X-band EPR spectra of Co²⁺ in single crystalline Zn₁₋xCoxO (x = 0.001–0.075) thin films grown by plasma-assisted molecular beam epitaxy. By analyzing the EPR linewidth behavior we argue that the exchange-narrowing ...

    Sushko, M.Ya. (Физика низких температур, 2007)
    The effect of the 1.5-scattering mechanism on the time and temperature behavior of the electric field autocorrelation function for the light wave scattered from fluids has been studied for the case where the order- parameter ...
  • From optical spectra to phase diagrams — the binary mixture N2–CO 
    Vetter, M.; Brodyanski, A.; Jodl, H.-J. (2007)
    We investigated the T–c% phase diagram of the binary system N2–CO. From changes in IR spectra of all kinds of mode excitations (phonons, vibrons) we were able to determine the temperature of phase transitions (solid–solid, ...

    Gorelik, L.Y.; Kulinich, S.I.; Shekhter, R.I.; Jonson, M.; Vinokur, V.M. (Физика низких температур, 2007)
    We study transport of spin-polarized electrons through a magnetic single-electron transistor (SET) in the presence of an external magnetic field. Assuming the SET to have a nanometer-sized central island with a single ...
