It also presents the only detailed historiographical research on the spin glass theory. Despite the extreme simplicity of their definition, spin glasses display a wide variety of non-trivial behaviors that are not yet fully understood. In this thesis the author sheds light on some of these, focusing on both the search for phase transitions under perturbations of Hamiltonians and the zero-temperature properties and responses to external stimuli. After introducing spin glasses and useful concepts on phase transitions and numerics, the results of two massive Monte Carlo campaigns on three-dimensional systems are presented: The first of these examines the de Almeida–Thouless transition, and proposes a new finite-size scaling ansatz, which accelerates the convergence to the thermodynamic limit. The second reconstructs the phase diagram of the Heisenberg spin glass with random exchange anisotropy. .Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053Phase transitions (Statistical physics)PhysicsCeramicsGlassComposites (Materials)Composite materialsQuantum computersSpintronicsPhase Transitions and Multiphase Systemshttps://scigraph.springernature.com/ontologies/product-market-codes/P25099Numerical and Computational Physics, Simulationhttps://scigraph.springernature.com/ontologies/product-market-codes/P19021Ceramics, Glass, Composites, Natural Materialshttps://scigraph.springernature.com/ontologies/product-market-codes/Z18000Quantum Information Technology, Spintronicshttps://scigraph.springernature.com/ontologies/product-market-codes/P31070History and Philosophical Foundations of Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P29000Phase transitions (Statistical physics).Physics.Ceramics.Glass.Composites (Materials).Composite materials.Quantum computers.Spintronics.Phase Transitions and Multiphase Systems.Numerical and Computational Physics, Simulation.Ceramics, Glass, Composites, Natural Materials.Quantum Information Technology, Spintronics.History and Philosophical Foundations of Physics.541.28Baity Jesi Marcoauthttp://id.loc.gov/vocabulary/relators/aut810999MiAaPQMiAaPQMiAaPQBOOK9910254634103321Spin Glasses2522532UNINA
