Structure and statistical properties of the semiclassical Einstein equations
Daniel R. Terno
We treat the semiclassical Einstein equation as a quantum-classical hybrid and demonstrate the formal equivalence of its two derivation methods. This approach identifies the left-h…
Semi-classical imprints on quasinormal mode spectra
Fil Simovic, Daniel R. Terno
We compute quasinormal mode frequencies for static limits of physical black holes - semi-classical black hole solutions to Einstein-Hilbert gravity characterized by the finite form…
Paradoxes before the paradox: surface gravity and the information loss problem
Robert B. Mann, Sebastian Murk, Daniel R. Terno
The information loss paradox is widely regarded as one of the biggest open problems in theoretical physics. Several classical and quantum features must be present to enable its for…
Unification of energy concepts in generalised phase space theories
Libo Jiang, Daniel R. Terno, Oscar Dahlsten
We consider how to describe Hamiltonian mechanics in generalised probabilistic theories with the states represented as quasi-probability distributions. We give general operational…
From reasonable postulates to generalised Hamiltonian systems
Libo Jiang, Daniel R. Terno, Oscar Dahlsten
Hamiltonian mechanics describes the evolution of a system through its Hamiltonian. The Hamiltonian typically also represents the energy observable, a Noether-conserved quantity ass…
Classical-Quantum Hybrid Models
Daniel R. Terno
Hybrid classical-quantum models are computational schemes that investigate the time evolution of systems, where some degrees of freedom are treated classically, while others are de…
