= Transverse-field Ising model
{wiki=Transverse-field_Ising_model}
The transverse-field Ising model (TFIM) is a fundamental model in statistical mechanics and quantum physics used to study phase transitions and quantum critical phenomena. It is an extension of the classical Ising model, which describes spins on a lattice that can take on values of +1 or -1, interacting with their neighbors. In the TFIM, in addition to the nearest-neighbor interactions, a transverse magnetic field is applied, which influences the spins in a direction perpendicular to the Ising interactions.
