Quantum Phase Transitions | SpringerLink

Quantum phase transitions occur at zero temperature when some non-thermal parameter like pressure, chemical composition or magnetic field is changed.

Quantum Phase Transitions in periodically quenched systems

Here we propose an alternative approach where the control parameter undergoes abrupt and time-periodic jumps between only two values.

A series of advances seemed to promise the impossible: the existence of quantum states that would never, ever fall into disarray. But physicists are now ...

Size-driven quantum phase transitions | PNAS

This sudden and dramatic change in the nature of the ground state may be viewed as a type of quantum phase transition, driven by the system size rather than a ...
