Hey I've been looking all over the web and I can't find any comprehensible information on overlap integrals. What does the overlap integral of two functions give us? And why?
Thanks in advance!
Thanks in advance!

Overlap integrals are mathematical calculations used in quantum mechanics to determine the extent to which two quantum wavefunctions overlap. They provide a measure of the probability that two particles will occupy the same space at the same time.
The formula for overlap integrals involves taking the product of the two wavefunctions, multiplying by a factor that accounts for the distance between the two particles, and then integrating over all space. This calculation can be done analytically or numerically using computer software.
Overlap integrals are essential for understanding the behavior of particles in quantum systems. They help us determine the likelihood of particle interactions and the stability of molecular structures. They also play a crucial role in predicting the physical and chemical properties of materials.
The value of overlap integrals depends on the nature and shape of the two wavefunctions involved, as well as the distance between the two particles. It is also affected by the orientation of the particles and the presence of any barriers or potential energy barriers between them.
Overlap integrals have numerous applications in fields such as chemistry, physics, and materials science. They are used to predict molecular properties, study chemical reactions, and design new materials with specific properties. They are also essential in fields such as quantum computing and quantum cryptography.
