Quantum Simulation of the Early Universe
How quantum simulation can model processes of the early universe, such as field dynamics and particle creation, and what remains out of reach.
Quantum Gases: Bose-Einstein Condensates Explained
Quantum gases are atoms cooled to near absolute zero. Bose-Einstein condensates, degenerate Fermi gases, superfluidity and experiments.
Quantum Liquids: Helium, Superfluids and Order
Quantum liquids such as helium-3 and helium-4 show superfluidity and other collective quantum effects. Their physics, experiments and uses.
Quantum Heat Engines and Their Efficiency Limits
Quantum heat engines use quantum systems as working media. How they relate to the Carnot limit, the models studied and experiments.
Quantum Electrodynamics: The Theory and Its Tests
Quantum electrodynamics and its experimental tests: Feynman diagrams, renormalization, virtual particles, vacuum fluctuations and precision checks.
Quantum Probability Theory and Where It Differs
Quantum probability differs from classical probability because observables do not commute. How the rules work and where they are used.
Quantum Logic: The Algebra of Quantum Propositions
Quantum logic, introduced by Birkhoff and von Neumann in 1936, replaces classical logic with the lattice of quantum propositions. Ideas and uses.
Quantum Foundations: The Questions Still Open
The open questions in the foundations of quantum mechanics: measurement, interpretation, non-locality and what the theory says about reality.
