# Quantum Mechanics

• Born Rule - The Born rule defines the relationship between the state of a quantum system and the probabilities of its possible outcomes based on probability density.
• De Broglie Wavelength Formula - The De Broglie wavelength formula relates the wavelength of a particle to its momentum and Planck's constant.
• Density Matrix Formalism - The density matrix formalism represents a quantum state in a mixed state and is essential for handling open quantum systems and quantum information theory.
• Electron-volts to Volts - This converter allows for the precise conversion of energy units from electron-volts to volts and is widely used in various branches of physics and engineering.
• Energy Level of a Hydrogen Atom (Bohr's Model) - Calculate the energy level (in electron volts) of an electron in a hydrogen atom based on its principal quantum number using Bohr's model.
• Bohr's Model - Energy Levels of Hydrogen Atom - Calculate the energy levels of a hydrogen atom in Bohr's model using the principal quantum number.
• Flux Quantization in a Superconducting Loop (SQUID) - Flux quantization in a superconducting loop is integral to understanding SQUIDs, where magnetic flux is quantized and occurs in integer multiples of the flux quantum Φ₀.
• Gell-Mann Matrices - The Gell-Mann matrices are a set of eight 3x3 traceless Hermitian matrices used in the mathematical formulation of quantum mechanics.
• Pauli Exclusion Principle - The Pauli exclusion principle is a fundamental principle in quantum mechanics that governs the behavior of fermions.
• Planck's Energy of a Photon - Planck's energy of a photon formula calculates the energy (E) associated with a photon given its frequency (ν) using Planck's constant (h).
• Quantum Angular Momentum - Quantum angular momentum is a measure of the rotation of an object. This calculator helps calculate quantum angular momentum using mass, velocity, and radius.
• Quantum Teleportation Protocol - The Quantum Teleportation Protocol is a fundamental concept in quantum mechanics allowing the transfer of quantum information from one location to another.
• Virial Theorem - The Virial Theorem relates the average kinetic energy and potential energy in a bound system and is used in astrophysics and quantum mechanics.
