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. . 000756193 588__ $$aDescription based on print version record. 000756193 650_0 $$aSpin glasses. 000756193 650_0 $$aPhysics. 000756193 650_0 $$aPhase transformations (Statistical physics) 000756193 650_0 $$aQuantum computers. 000756193 650_0 $$aSpintronics. 000756193 77608 $$iPrint version:$$aBaity Jesi, Marco$$tSpin Glasses : Criticality and Energy Landscapes$$dCham : Springer International Publishing,c2016$$z9783319412306 000756193 830_0 $$aSpringer theses. 000756193 852__ $$bebk 000756193 85640 $$3SpringerLink$$uhttps://univsouthin.idm.oclc.org/login?url=http://link.springer.com/10.1007/978-3-319-41231-3$$zOnline Access$$91397441.1 000756193 909CO $$ooai:library.usi.edu:756193$$pGLOBAL_SET 000756193 980__ $$aEBOOK 000756193 980__ $$aBIB 000756193 982__ $$aEbook 000756193 983__ $$aOnline 000756193 994__ $$a92$$bISE
