Searching for the Magnetic Interactions in the Rare Earth Pyrochlore Oxide Yb₂Ti₂O₇
(University of Waterloo, 2011-07-20)Various experiments on Yb₂Ti₂O₇ have shown evidence of strange magnetic behaviour at low temperatures. Specific heat measurements on powder samples of Yb₂Ti₂O₇ show evidence of a sharp peak, indicating the occurence of a ... -
A study of the effect of perturbations in spin ice systems: site dilution, weak exchange, quantum and finite-size effects
(University of Waterloo, 2014-08-20)In this thesis we investigate a range of properties for spin ice under various perturbations theoretically. Diluted spin ices, Dy2−x Yx Ti2 O7 and Ho2−x Yx Ti2 O7 , where the magnetic rare-earth ions Dy3+ and Ho3+ are ... -
Study of the Exotic Ground State Physics in XXZ Quantum Spin Ice
(University of Waterloo, 2014-09-02)Three dimensional frustrated magnets realized in the rare-earth pyrochlores R_2B_2O_7, R=rare-earth ion, B transition metal ion) have attracted much interest since the discovery of spin ice in Ho_2Ti_2O_7 by Harris et al. ... -
Topological Order in String Liquids and Weyl Semimetals
(University of Waterloo, 2022-08-22)Outside Landau's paradigm of symmetry-breaking orders is the class of topological orders, which cannot be described by a local order parameters. Such orders are generally defined by the presence of a gauge symmetry and ...
