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 Optomechanics: Light Moving Mirrors
Quantum optomechanics couples light to mechanical motion. Radiation pressure, ground-state cooling, squeezing and uses in sensing.
Quantum Turbulence: Vortices in a Superfluid
Quantum turbulence is a tangle of quantized vortices in a superfluid such as liquid helium. How it differs from classical turbulence.
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 Spintronics: Using Spin Instead of Charge
Spintronics stores and moves information in electron spin rather than charge. Spin manipulation, spin-orbit effects and quantum spin devices.
Quantum Nanoelectronics: Devices at the Atomic Scale
Quantum nanoelectronics builds devices where quantum effects dominate, including quantum dots, superconducting qubits and spintronic parts.
Quantum Electrodynamics: The Theory and Its Tests
Quantum electrodynamics and its experimental tests: Feynman diagrams, renormalization, virtual particles, vacuum fluctuations and precision checks.
Quantum Homotopy Theory: Topology Meets Quantum
Quantum homotopy theory connects algebraic topology with quantum structures such as quantum groups. Its concepts, applications and open questions.
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.
