Classical Integrable Systems
In the Introduction to Classical and Quantum Integrable Systems cite:bimsa.net, classical integrable systems refer to those described by Hamiltonian mechanics. These systems have as many conserved quantities as degrees of freedom, making them solvable through elegant mathematical techniques.
Key Features of Classical Systems:
- Conserved Quantities: Physical properties like energy, momentum, and angular momentum remain constant during motion.
- Action-Angle Variables: These are special coordinates that simplify solving equations of motion.
Examples of Classical Integrable Systems:
- Harmonic Oscillator: A system where a particle oscillates back and forth under a restoring force, like a mass on a spring.
- Kepler Problem: The motion of planets around the sun governed by gravitational forces.
- Spinning Tops: Objects rotating under gravitational torque, exhibiting conserved angular momentum.
Classical integrable systems help us understand regular and predictable behavior in mechanical systems.
Quantum Integrable Systems
The Introduction to Classical and Quantum Integrable Systems cite:bimsa.net also delves into quantum integrable systems, which describe systems at the quantum level. Unlike classical systems, these rely on quantum operators and wave functions.
Key Features of Quantum Systems:
- Quantum Conservation Laws: Instead of conserved quantities, quantum systems use commuting operators to describe measurable constants.
- Bethe Ansatz: A powerful method for solving quantum integrable systems by finding exact solutions to wave equations.
Examples of Quantum Integrable Systems:
- Quantum Harmonic Oscillator: The quantum version of the classical oscillator where energy levels are quantized.
- Spin Chains: Systems of interacting quantum spins, such as those described by the Heisenberg model in statistical mechanics.
- Quantum Field Theories: Symmetry-based models that describe particles and fields.
Quantum integrable systems are essential for understanding atomic, molecular, and condensed matter physics.
