The Geometric Foundations of Microcanonical Thermodynamics: Entropy Flow Equation and Thermodynamic Equivalence
Loris Di Cairano
We develop a geometric foundation of microcanonical thermodynamics in which entropy and its derivatives are determined from the geometry of phase space, rather than being introduce…

Repulsive Inverse-Distance Interatomic Interaction from Many-Body Quantum Electrodynamics
Loris Di Cairano, Matteo Gori, Reza Karimpour +1
Interactions between objects can be classified as fundamental or emergent. Fundamental interactions are either extremely short-range or decay inversely with the separation distance…

Hamiltonian chaos and differential geometry of configuration space-time
Loris Di Cairano, Matteo Gori, Giulio Pettini +1
This paper tackles Hamiltonian chaos by means of elementary tools of Riemannian geometry. More precisely, a Hamiltonian flow is identified with a geodesic flow on configuration spa…
