  1. 1. Resistivity and the solid-to-liquid transition in high-temperature superconductors

    University dissertation from Stockholm : KTH

    Author : Beatriz Espinosa Arronte; KTH.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; high-temperature superconductors; vortex dynamics; vortex solid-to-liquid transition; critical scaling; glass transition; Bose glass; heavy-ion irradiation; YBCO; Tl2Ba2CaCu2O8 d; oxygen deficiency.; NATURAL SCIENCES Physics Condensed matter physics; NATURVETENSKAP Fysik Kondenserade materiens fysik;

    Abstract : In high-temperature superconductors a large region of the magnetic phase diagram is occupied by a vortex phase that displays a number of exciting phenomena. At low temperatures, vortices form a truly superconducting solid phase which at high temperatures turns into a dissipative vortex liquid. READ MORE

  2. 2. Phase transitions in novel superfluids and systems with correlated disorder

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Hannes Meier; KTH.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; condensed matter physics; phase transitions; critical phenomena; spin models; quantum phase transitions; quantum fluids; superfluidity; superconductivity; disordered systems; Bose glass; dirty bosons; vortex pinning; statistical mechanics; Monte Carlo simulation; Wolff algorithm; classical worm algorithm; Wang-Landau algorithm; Physics; Fysik;

    Abstract : Condensed matter systems undergoing phase transitions rarely allow exact solutions. The presence of disorder renders the situation  even worse but collective Monte Carlo methods and parallel algorithms allow numerical descriptions. READ MORE

  3. 3. Superfluid Phase Transitions in Disordered Systems

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Hannes Meier; KTH.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis presents results from large scale Monte Carlo simulations of systems subject to a superfluid phase transition in the presence of disorder. The simulations are performed by state-of-the-art, collective Monte Carlo algorithms treating phase degrees of freedom in effective models with amplitude fluctuations integrated out. READ MORE
