“…The theoretical investigation of out-of-equilibrium strongly correlated quantum systems recently generated a tremendous interest, stimulated by the development of novel experimental techniques, which allow to explore transport properties of correlated materials in a non-equilibrium regime, [1][2][3] notwithstanding the recent achievements in the field of optically trapped cold-atoms. These experimental advances challenge the theory to develop suitable new methods to describe how a strongly correlated materials evolves when an external field pushes it out-of-equilibrium.…”

“…T he ultrafast control of a material's properties via nonequilibrium states is a new method to manipulate and control the structural 1 , magnetic 2 and electrical 3 properties of materials that may not be accessible under equilibrium conditions. The timescale on which one phase is lost and a new phase emerges is of fundamental interest for understanding how these transitions occur as well as being important for potential applications.…”

Ultrafast changes in lattice symmetry probed by coherent phonons

The electronic and structural properties of a material are strongly determined by its symmetry. Changing the symmetry via a photoinduced phase transition offers new ways to manipulate material properties on ultrafast timescales. However, to identify when and how fast these phase transitions occur, methods that can probe the symmetry change in the time domain are required. Here we show that a time-dependent change in the coherent phonon spectrum can probe a change in symmetry of the lattice potential, thus providing an all-optical probe of structural transitions. We examine the photoinduced structural phase transition in Vo 2 and show that, above the phase transition threshold, photoexcitation completely changes the lattice potential on an ultrafast timescale. The loss of the equilibrium-phase phonon modes occurs promptly, indicating a non-thermal pathway for the photoinduced phase transition, where a strong perturbation to the lattice potential changes its symmetry before ionic rearrangement has occurred.

“…Different tools have been developed for different experimental systems. Important examples are various cold-atom setups [1][2][3][4][5][6] , ultra-fast pump-probe spectroscopy of quantum materials [7][8][9][10] , and heavy-ion collisions that explore the dynamics of the quark-gluon plasma 11 . These experiments clearly reveal that observations far away from equilibrium can yield new insights.…”

Universal postquench coarsening and aging at a quantum critical point

The non-equilibrium dynamics of a system that is located in the vicinity of a quantum critical point is affected by the critical slowing down of order-parameter correlations with the potential for novel out-of-equilibrium universality. After a quantum quench, i.e. a sudden change of a parameter in the Hamiltonian such a system is expected to almost instantly fall out of equilibrium and undergo aging dynamics, i.e. dynamics that depends on the time passed since the quench. Investigating the quantum dynamics of a N -component ϕ 4 -model coupled to an external bath, we determine this universal aging and demonstrate that the system undergoes a coarsening, governed by a critical exponent that is unrelated to the equilibrium exponents of the system. We analyze this behavior in the large-N limit, which is complementary to our earlier renormalization group analysis, allowing in particular the direct investigation of the order-parameter dynamics in the symmetry broken phase and at the upper critical dimension. By connecting the long time limit of fluctuations and response, we introduce a distribution function that shows that the system remains non-thermal and exhibits quantum coherence even on long timescales.
