Magnetic phases of large-spin ultracold bosons: quantum dimer models and spin liquid phases
… spin this Hamiltonian produces a type of quantum dimer model (QDM), which are known to possess QSL phases. We derive the QDM parameters <em>t, t</em>′ and <em>V</em> as a function of spin on several lattices, finding they scale with the inverse number of Zeeman sublevels. We then determine the …

Studies of Topology and Order in Frustrated Spin Systems
… matter, as they emerge in tractable quantum spin models, and we make several original contributions. In this dissertation, (a) we study quantum dimer models with frustrating interactions and holes, identifying possible phases of matter and the nature of the phase transitions between them, (b) we …

Macroscopic behaviour of Lipschitz random surfaces
… Random fields and random surfaces serve as toy models for analysing several phenomena in statistical physics: examples include percolation models, the Ising model, dimer models, the discrete Gaussian free field, and uniformly random Lipschitz functions. We analyse the specific free energy …

Mocking quantum mechanics: Semiclassical and machine-learning approaches to frustrated magnetism
… power laws in one-dimensional quasiperiodic models, and of a two-dimensional quasicrystal in which localised and partially extended states coexist without a mobility edge.

Pair density wave superconducting states and statistical mechanics of dimers
… classical statistical mechanics properties of dimers, in particular, the dimer model on the Aztec diamond graph and its relation with the octahedron equation. In chapter 2 we present a theory of superconducting states where the Cooper pairs have a nonzero center-of-mass momentum, inhomogeneous …
