A concept – quantum order – is introduced to describe a new kind of orders that generally appear in quantum states at zero temperature. Quantum orders that characterize universality classes of quantum states (described by complex ground state wave-functions) is much richer then classical orders that characterize universality classes of finite temperature classical states (described by positive probability distribution functions). The Landau’s theory for orders and phase transitions does not… CONTINUE READING
