"In statistical mechanics, the grand canonical ensemble (also known as the macrocanonical ensemble) is the statistical ensemble that is used to represent the possible states of a mechanical system of particles that are in thermodynamic equilibrium (thermal and chemical) with a reservoir."
An ensemble of systems that are in thermal and chemical equilibrium with each other.
Introduction to Statistical Mechanics: This covers the basic principles and concepts of statistical mechanics, such as ensembles, entropy, and probability distribution functions.

Nonequilibrium Statistical Mechanics: This examines nonequilibrium statistical mechanics and its application to systems that are not in equilibrium.
Entropy and Information Theory: This covers the principles of entropy and information theory and their application in statistical mechanics.
Ideal gas Grand Canonical ensemble: This ensemble is characterized by the assumption that the particles constituting the system behave like an ideal gas, and their number, volume, and energy can fluctuate.
Lattice Grand Canonical ensemble: This ensemble is suited for analyzing systems in which each particle can only exist at sites on a lattice.
Spin Grand Canonical ensemble: This ensemble is used to study magnetic properties of systems in which each site of the lattice can be occupied by a magnetic dipole whose direction is determined by a spin.
Boson Grand Canonical ensemble: This ensemble is suitable for systems in which only bosons constituting the system can occupy a given energy level.
Fermion Grand Canonical ensemble: This ensemble is suited for systems in which only fermions constituting the system can occupy a given energy level.
Classical Grand Canonical ensemble: This ensemble is used to study classical systems that exist at a fixed temperature and chemical potential.
Quantum Grand Canonical ensemble: This ensemble is very similar to the classical Grand Canonical ensemble, but it is used to study quantum systems that exist at a fixed temperature and chemical potential.
Electrolyte Grand Canonical ensemble: This ensemble is used to study electrolytes, which are materials that dissolve in a solvent and conduct electricity.
"The system is said to be open in the sense that the system can exchange energy and particles with a reservoir, so that various possible states of the system can differ in both their total energy and total number of particles."
"The thermodynamic variables of the grand canonical ensemble are chemical potential (symbol: µ) and absolute temperature (symbol: T)."
"The ensemble is also dependent on mechanical variables such as volume (symbol: V) which influence the nature of the system's internal states."
"This ensemble is therefore sometimes called the µVT ensemble, as each of these three quantities are constants of the ensemble."
