Quantum Mechanics
- It describes nature's physical properties at the atomic and subatomic level
- Quantum mechanics is a fundamental theory in physics describing nature at the atomic and subatomic level
- It provides a mathematical framework for understanding matter and energy behavior at the atomic and subatomic level
Key Concepts of Quantum Mechanics
- Quantization: Physical quantities of a bound system are restricted to discrete values
- Wave-Particle Duality: Particles exhibit wave-like properties, and waves exhibit particle-like properties
- Uncertainty Principle: There is a fundamental limit to the precision with which certain pairs of physical properties of a particle can be known simultaneously
- Superposition: A quantum system can exist in multiple states simultaneously
- Entanglement: Quantum systems can be linked, sharing the same fate regardless of distance
Schrödinger Equation
- Describes the time evolution of a quantum system
Time-Dependent Schrödinger Equation
- $i\hbar\frac{\partial}{\partial t}\Psi(r, t) = \hat{H}\Psi(r, t)$
- $i$ is the imaginary unit
- $\hbar$ is the reduced Planck constant
- $\frac{\partial}{\partial t}$ is the partial derivative with respect to time
- $\Psi(r, t)$ is the wave function of the quantum system
- $\hat{H}$ is the Hamiltonian operator, representing the total energy of the system
Time-Independent Schrödinger Equation
- $E\Psi(r) = \hat{H}\Psi(r)$
- $E$ is the energy of the system
- $\Psi(r)$ is the time-independent wave function
Applications of Quantum Mechanics
- Quantum Computing: Uses superposition and entanglement for computations
- Quantum Cryptography: Secures information transmission using quantum mechanics principles
- Materials Science: Used to design new materials with specific properties
- Medical Imaging: Used in MRI and PET scans
Key Figures in Quantum Mechanics
- Max Planck introduced the concept of quantization of energy
- Albert Einstein explained the photoelectric effect and introduced photons
- Niels Bohr developed the Bohr model of the atom
- Werner Heisenberg formulated the uncertainty principle
- Erwin Schrödinger developed the Schrödinger equation
- Paul Dirac made contributions to quantum mechanics and quantum electrodynamics
