Wave function overlap quantifies the degree to which two quantum states share the same spatial region and is crucial for understanding phenomena like quantum tunneling and chemical bonding. It is represented mathematically by the integral of the product of the two wave functions, indicating the probability amplitude of finding particles in the same state.

Quantum states are the fundamental entities in quantum mechanics that encapsulate all the information about a quantum system, typically represented by wave functions or state vectors in a Hilbert space. Their probabilistic nature underlies the inherent uncertainties and phenomena such as superposition and entanglement, distinguishing them from classical states.

Quantum tunneling is a quantum mechanical phenomenon where particles pass through a potential energy barrier that they classically shouldn't be able to surmount. This process is crucial in various physical phenomena and technologies, including nuclear fusion in stars and the operation of tunnel diodes and scanning tunneling microscopes.

Chemical bonding is the process by which atoms combine to form molecules and compounds, driven by the attainment of a more stable electronic configuration. The main types of chemical bonds are ionic, covalent, and metallic, each involving different mechanisms of electron sharing or transfer.

Mathematical Representation

Probability amplitude is a complex number used in quantum mechanics to describe the behavior of quantum systems, where its magnitude squared gives the probability of a particular outcome. It plays a central role in the formulation of quantum mechanics, particularly in the superposition and interference of quantum states.
