    "abstract": "We investigate the relationship between ground-state (zero-temperature)\nquantum phase transitions in systems with variable Hamiltonian parameters and\nclassical (temperature-driven) phase transitions in standard thermodynamics. An\nanalogy is found between (i) phase-transitional distributions of the\nground-state related branch points of quantum Hamiltonians in the complex\nparameter plane and (ii) distributions of zeros of classical partition\nfunctions in complex temperatures. Our approach properly describes the first-\nand second-order quantum phase transitions in the interacting boson model and\ncan be generalized to finite temperatures.",
