Multicritical crossovers near the dilute bose gas quantum critical point.
Many zero temperature transitions, involving the deviation in the value of a U(1) conserved charge from a quantized value, are described by the dilute Bose gas quantum critical point. On such transitions, we study the consequences of perturbations which break the symmetry down to ZN in d spatial dimensions. For the case d = 1, N = 2, we obtain exact, finite temperature, multicritical crossover ...
متن کاملCritical exponent crossovers in escape near a bifurcation point.
In periodically driven systems, near a bifurcation (critical) point the period-averaged escape rate Wmacr; scales with the field amplitude A as |ln(Wmacr;| proportional, variant (A(c)-A)(xi), where A(c) is a critical amplitude. We find three scaling regions. With increasing field frequency or decreasing |A(c)-A|, the critical exponent xi changes from xi=3/2 for a stationary system to a dynamica...
متن کاملFermi Liquid near a Quantum Critical Point *
We investigate the approach to the quantum critical point of a Pomeranchuk instability from the symmetric, disordered side of the phase diagram. In the low-temperature limit, a Fermi liquid description of the metal is possible and becomes exact for T → 0. We discuss in detail which features of the approach to quantum criticality can be captured within Fermi liquid theory and which are outside o...
متن کاملQuench 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 کاملA quantum critical trio: solvable models of finite temperature crossovers near quantum phase transitions
The physics of three simple solvable quantum models is reviewed in some detail: the spin 1/2 XX chain (and the related dilute spinless Fermi gas), the Ising chain in a transverse field, and the large N limit of the O(N) quantum rotor model. A unified scaling description is presented, and the many common features among the models are highlighted. The crossovers in these systems are the simplest ...
