In recent years, quantum phase transitions have attracted the interest of both theorists and experimentalists in condensed matter physics. These transitions, which are accessed at zero temperature by variation of a non-thermal control parameter, can influence the behaviour of electronic systems over a wide range of the phase diagram. Quantum phase transitions occur as a result of competing ground state phases. The cuprate superconductors which can be tuned from a Mott insulating to a d-wave…

Why first order quantum phase transitions are interesting

It is frequently argued that only second order phase transitions at T = 0 deserve to be called quantum phase transitions, while first order quantum phase transitions are a contradiction in terms.

Geometry of quantum phase transitions

Quantum Phase Transitions with Parity-Symmetry Breaking and Hysteresis.

This work reports for the first time the experimental observation of the full quantum phase diagram across a transition where the spatial parity symmetry is broken, and shows the robustness of the asymmetric state against controlled energy mismatch between the two wells.

Signature of a continuous quantum phase transition in non-equilibrium energy absorption: Footprints of criticality on higher excited states

Signature of a quantum critical point manifested in strongly out-of-equilibrium states with finite energy density with respect to the ground state and extensive (subsystem) entanglement entropy, generated by an external pulse is reported.

Impurity quantum phase transitions

Recent work is reviewed on continuous quantum phase transitions in impurity models, both with fermionic and bosonic baths – these transitions are interesting realizations of boundary critical

Observation of a quantum phase transition in the quantum Rabi model with a single trapped ion

An experimental demonstration of a QPT in the QRM using a 171Yb+ ion in a Paul trap and clear evidence of the phase transition via adiabatic tuning of the coupling between the ion and its spatial motion is observed.

Quantum phase transitions in coupled atom-photon systems

Quantum many-body phase transitions have attracted a great deal of theoretical and experimental study in both naturally-occurring systems like those in condensed matter and man-made systems created

Excited-state quantum phase transitions in Kerr nonlinear oscillators

Excited-state quantum phase transitions (ESQPTs) generalize the concept of quantum phase transitions to excited levels. Here we investigate how such ESQPTs can emerge in Kerr nonlinear oscillators,



Continuous quantum phase transitions

A quantum system can undergo a continuous phase transition at the absolute zero of temperature as some parameter entering its Hamiltonian is varied. These transitions are particularly interesting

Quantum phase transition from a superfluid to a Mott insulator in a gas of ultracold atoms

This work observes a quantum phase transition in a Bose–Einstein condensate with repulsive interactions, held in a three-dimensional optical lattice potential, and can induce reversible changes between the two ground states of the system.

Locally critical quantum phase transitions in strongly correlated metals

The theoretical finding of a locally critical quantum phase transition in a model of heavy fermions is reported, and local criticality is proposed to be a phenomenon of general relevance to strongly correlated metals.

Boson localization and the superfluid-insulator transition.

It is argued that the superfluid-insulator transition in the presence of disorder may have an upper critical dimension dc which is infinite, but a perturbative renormalization-group calculation wherein the critical exponents have mean-field values for weak disorder above d=4 is also discussed.

Quantum phase transitions in models of coupled magnetic impurities

We discuss models of interacting magnetic impurities coupled to a metallic host, which show one or more boundary quantum phase transitions where the ground-state spin changes as a function of the

Electronic liquid-crystal phases of a doped Mott insulator

The character of the ground state of an antiferromagnetic insulator is fundamentally altered following addition of even a small amount of charge. The added charge is concentrated into domain walls

Why Quantum Phase Transitions Are Interesting

This paper discusses why the usual notion that quantum phase transitions can be mapped onto classical phase transitions in a higher dimension, and that this makes the former uninteresting from a

Local versus nonlocal order-parameter field theories for quantum phase transitions

General conditions are formulated that allow us to determine which quantum phase transitions in itinerant electron systems can be described by a local Landau-Ginzburg-Wilson (LGW) theory solely in

Quantum criticality: competing ground states in low dimensions

Nonzero temperature dynamic properties near quantum critical points and possible quantum phases and transitions in the two-dimensional electron gas on a square lattice are discussed.

The Anderson-Mott transition

The interacting disordered electron problem is reviewed with emphasis on the quantum phase transitions that occur in a model system and on the field-theoretic methods used to describe them. An
