Quantum phase transitions

Continuous phase transitions that occur at zero temperature as a result of quantum fluctuations required by Heisenberg’s uncertainty principle are called quantum phase transitions. In the present paper an elementary introduction to quantum phase transitions is given. A few experimental examples from the physics of heavy-fermion systems and itinerant ferromagnets are described.
