The statistical physics of graphs and partition functions represents a vibrant intersection of graph theory, statistical mechanics and computational complexity. By summing over an ensemble of ...

Quantum graphs are commonly used as models of complex quantum systems, for example molecules, networks of wires and states of condensed matter. We consider quantum statistics for indistinguishable ...

Additionally, foundational investigations into the complexity of approximating complex-valued partition functions have reinforced the pivotal role of these functions in bridging statistical ...
