  • The large-m limit, and spin liquid correlations in kagome-like spin models 
    Yavors'kii, T. (Condensed Matter Physics, 2017)
    It is noted that the pair correlation matrix χˆ of the nearest neighbor Ising model on periodic three-dimensional (d = 3) kagome-like lattices of corner-sharing triangles can be calculated partially exactly. Specifically, ...
  • Behavior of the impurity atom in a weakly-interacting Bose gas 
    Panochko, G.; Pastukhov, V.; Vakarchuk, I. (Condensed Matter Physics, 2017)
    We studied the properties of a single impurity atom immersed in a dilute Bose condensate at low temperatures. In particular, we perturbatively obtained the momentum dependence of the impurity spectrum and damping. By ...
  • Emergent universal critical behavior of the 2D N-color Ashkin-Teller model in the presence of correlated disorder 
    Dudka, M.; Fedorenko, A.A. (Condensed Matter Physics, 2017)
    We study the critical behavior of the 2D N-color Ashkin-Teller model in the presence of random bond disorder whose correlations decays with the distance r as a power-law r −a . We consider the case when the spins ...
  • Laudation on the occasion of the 70th anniversary of Ivan Vakarchuk 
    Автор відсутній (Condensed Matter Physics, 2017)
    Ivan Vakarchuk, a leading Ukrainian physicist, Minister of Education and Science of Ukraine (2007– 2010), Rector of Ivan Franko National University of Lviv (1990–2007, 2010–2013) is celebrating his 70th anniversary on ...
  • Shape characteristics of the aggregates formed by amphiphilic stars in water: dissipative particle dynamics study 
    Kalyuzhnyi, O.Y.; Ilnytskyi, J.M.; C. von Ferber (Condensed Matter Physics, 2017)
    We study the effect of the molecular architecture of amphiphilic star polymers on the shape of aggregates they form in water. Both solute and solvent are considered at a coarse-grained level by means of dissipative ...
  • Synaptic transmission as a cooperative phenomenon in confined systems 
    Chalyi, A.V.; Vasilev, A.N.; Zaitseva, E.V. (Condensed Matter Physics, 2017)
    In this review paper, the theory of synaptic transmission (ST) was developed and discussed. We used the hypothesis of isomorphism between: (a) the cooperative behavior of mediators — acetylcholine molecules (ACh) and ...
  • Negative response to an excessive bias by a mixed population of voters 
    Dotsenko, V.S.; Mejía-Monasterio, C.; Oshanin, G. (Condensed Matter Physics, 2017)
    We study an outcome of a vote in a population of voters exposed to an externally applied bias in favour of one of two potential candidates. The population consists of ordinary individuals, that are in majority and tend ...
  • A scientists' view of scientometrics: Not everything that counts can be counted 
    Kenna, R.; Mryglod, O.; Berche, B (Condensed Matter Physics, 2017)
    Like it or not, attempts to evaluate and monitor the quality of academic research have become increasingly prevalent worldwide. Performance reviews range from at the level of individuals, through research groups ...
  • Voids in the Cosmic Web as a probe of dark energy 
    Novosyadlyj, B.; Tsizh, M. (Condensed Matter Physics, 2017)
    The formation of large voids in the Cosmic Web from the initial adiabatic cosmological perturbations of spacetime metric, density and velocity of matter is investigated in cosmological model with the dynamical dark ...
  • Rashba spin-orbit interaction enhanced by graphene in-plane deformations 
    Berche, B.; Mireles, F.; Medina, E. (Condensed Matter Physics, 2017)
    Graphene consists in a single-layer carbon crystal where 2pz electrons display a linear dispersion relation in the vicinity of the Fermi level, conveniently described by a massless Dirac equation in 2+1 spacetime. ...
  • Helmholtz decomposition theorem and Blumenthal's extension by regularization 
    Petrascheck, D.; Folk, R. (Condensed Matter Physics, 2017)
    Helmholtz decomposition theorem for vector fields is usually presented with too strong restrictions on the fields and only for time independent fields. Blumenthal showed in 1905 that decomposition is possible for any ...
  • 60th birthday of Yurij Holovatch 
    C. von Ferber (Condensed Matter Physics, 2017)
    On June 16th 2017, Dr. Sci., Professor Yurij Holovatch, Head of the Laboratory for Statistical Physics of Complex Systems, Corresponding Member of the National Academy of Sciences of Ukraine, full member of the Shevchenko ...
  • Correlations, connections, and physics in complex systems 
    Berche, B.; Folk, R.; Kenna, R.; Mryglod, O. (Condensed Matter Physics, 2017)
    It is with great pleasure that we present, in this issue, a series of papers dedicated to the 60th birthday of Professor Yurij Holovatch. The broad spectrum of topics treated by the contributions reflect Yurij’s comprehensive ...
  • Investigating inequality: a Langevin approach 
    Eliazar, I. (Condensed Matter Physics, 2017)
    Inequality indices are quantitative scores that gauge the divergence of wealth distributions in human societies from the “ground state” of pure communism. While inequality indices were devised for socioeconomic applications, ...
  • Geometric characteristics of quantum evolution: curvature and torsion 
    Laba, H.P.; Tkachuk, V.M. (Condensed Matter Physics, 2017)
    We study characteristics of quantum evolution which can be called curvature and torsion. The curvature shows a deviation of the state vector in quantum evolution from the geodesic line. The torsion shows a deviation ...
  • Two-step percolation in aggregating systems 
    Lebovka, N.; Bulavin, L.; Kovalchuk, V.; Melnyk, I.; Repnin, K. (Condensed Matter Physics, 2017)
    The two-step percolation behavior in aggregating systems was studied both experimentally and by means of Monte Carlo (MC) simulations. In experimental studies, the electrical conductivity, σ, of colloidal suspension ...
  • Revisiting (logarithmic) scaling relations using renormalization group 
    Ruiz-Lorenzo, J.J. (Condensed Matter Physics, 2017)
    We explicitly compute the critical exponents associated with logarithmic corrections (the so-called hatted exponents) starting from the renormalization group equations and the mean field behavior for a wide class of ...
  • Scaling laws for random walks in long-range correlated disordered media 
    Fricke, N.; Zierenberg, J.; Marenz, M.; Spitzner, F.P.; Blavatska, V.; Janke, W. (Condensed Matter Physics, 2017)
    We study the scaling laws of diffusion in two-dimensional media with long-range correlated disorder through exact enumeration of random walks. The disordered medium is modelled by percolation clusters with correlations ...
  • Diffusion equations in inhomogeneous solid having arbitrary gradient concentration 
    Bilotsky, Y.; Gasik, M.; Lev, B. (Condensed Matter Physics, 2017)
    A quantum kinetic equation is obtained for an inhomogeneous solid having arbitrary gradient concentration and chemical potential. We find, starting from nonequilibrium statistical operator, a new equation to describe atom ...
