An explicit recipe for defining the Hamiltonian in general probabilistic theories, which have the potential to generalise quantum theory.
Spectroscopy experiments show that energy shifts due to photon emission from individual molecules satisfy a fundamental quantum relation.
A battery from which work is taken or given to a single heat bath.
A general analysis of exchange devices links their efficiency to the geometry of the exchange surface and supply network.
By analogy with Maxwell’s original thought experiment, the setup uses energy extracted from a thermal system.
Abstract depiction of the set of states, including the initial state ρ and final state σ . Each state is associated wi
Hypercubic Bethe lattices retain many of the loops of the topology of realistic spin systems.
