Quench dynamics near a quantum critical point
We study the dynamical response of a system to a sudden change of the tuning parameter starting or ending at the quantum critical point. In particular, we analyze the scaling of the excitation probability, number of excited quasiparticles, heat and entropy with the quench amplitude, and the system size. We extend the analysis to quenches with arbitrary power law dependence on time of the tuning...
متن کاملDynamics and Transport near Quantum-critical Points
The physics of non-zero temperature dynamics and transport near quantum-critical points is discussed by a detailed study of the O(N)symmetric, relativistic, quantum field theory of a N -component scalar field in d spatial dimensions. A great deal of insight is gained from a simple, exact solution of the long-time dynamics for the N = 1 d = 1 case: this model describes the critical point of the ...

We study the quantum dynamics of a number of model systems as their coupling constants are changed rapidly across a quantum critical point. The primary motivation is provided by the recent experiments of Greiner et al. (Nature 415, 39 (2002)) who studied the response of a Mott insulator of ultracold atoms in an optical lattice to a strong potential gradient. In a previous work, it had been argu...
متن کاملDeconfined quantum critical points.
The theory of second-order phase transitions is one of the foundations of modern statistical mechanics and condensed-matter theory. A central concept is the observable order parameter, whose nonzero average value characterizes one or more phases. At large distances and long times, fluctuations of the order parameter(s) are described by a continuum field theory, and these dominate the physics ne...
متن کاملFractionalized Quantum Critical Points
Groundstates of certain materials can support exotic excitations with a charge that’s a fraction of the fundamental electron charge. The condensation of these fractionalized particles has been predicted to drive novel quantum phase transitions, which haven’t yet been observed in realistic systems. Through numerical and theoretical analysis of a physical model of interacting lattice bosons, we e...
