These could allow for the generation of the matter-antimatter asymmetry or potentially observable gravitational waves. Quantum phase transitions have been the subject of intense investigations in the last two decades. 3. Furthermore, they can identify the order (first or second) of the phase transition by their behavior at the quantum transition point, which changes abruptly (smoothly) in the case of first-order (second-order) phase transitions. 0000007525 00000 n

Among other problems, these phase transitions are relevant in the study of heavy fermion systems, high-temperature superconductors and Bose–Einstein condensates. These effects are described theoretically using an action that takes into account the competition between different order parameters. The phase transition we just described involves a change of colour of parts of the ﬁgure, and colour is a scalar variable, so we expect we will need scalar modes.

In real crystal structures, there is a wide class of phase transitions, known as order-disorder phase transitions, which are described in terms of scalar modes.
