Dragan Mihailovic: Tutorial. Trajectories through emergent metastable states ‌in 2D correlated electron systems

Non-equilibrium states of matter have become of great fundamental and practical interest in recent years because of their wide importance in diverse areas of physics. With the rapid development of new time-resolved techniques, the temporal dynamics of competing processes and interactions were recently elucidated in a wide variety of complex condensed matter systems. However, the physics of metastable mesoscopically non-periodic quantum textures emerging from phase transitions has been largely...

Yuta Murakami: Possible hidden phases in photo-doped Mott insulators

Doping charge carriers into Mott insulators provides a pathway to produce intriguing emergent phenomena. In equilibrium systems, doping can be chemically controlled. On the other hand, photo-doping, where particles are excited across the Mott gap, provides an alternative way. Compared to chemical-doping, photo-doping creates a wider variety of charge carriers, which may lead to the emergence of fascinating nonequilibrium states. In particular, when the gap is large, the lifetime of photo-carr...

Zala Lenarčič: Tutorial. Flavours of Openness

I will introduce and review different aspects of open quantum systems dynamics, providing some background and motivation for the 2023 NQW talks with a flavour of openness.

Gergely Zarand: Non-equilibrium transport and quantum information jet ‌in the Hubbard model

In this presentation, I focus on the impact of interaction and symmetries on non-equilibrium charge and spin transport in the Hubbard model. The structure of non-equilibrium dynamics is found to change dramatically upon increasing interaction . In usual quench experiments, a relatively standard Fermi liquid-like behavior appears for small interactions, while phenomena such as composite particle formation along with negative temperature states emerge for larger interactions.

Denis Arčon: The pairing symmetry in the quasi-one-dimensional superconductors A2Mo3As3 (A=Rb, Cs)

The A2Mo3As3 (A = K, Rb, Cs) compounds are built of assembled Mo3As3 chains and are thus the potential realisations of quasi-one-dimensional metals. Various experiments on these materials hint to the Tomonaga-Luttinger liquid (TLL) physics from which superconductivity with a relatively high critical temperatures of Tc ≈ 10.5 K emerges. However, TLL and its relevance to emerging superconductivity are not yet resolved for A2Mo3As3 due to their multiband nature.Here we report a combined 75As n...

Nelson Hua: Ultrafast Electronic Domain Fluctuations Detected in a Nonequilibrium X-Ray Speckle Visibility Experiment

Since the advent of X-ray free electron lasers, a standard method to study metal-insulator transitions is in a nonequilibrium pump-probe diffraction experiment to disentangle how different order parameters evolve at ultrafast timescales. However, this technique is blind to domain fluctuations of the order parameter that may play a critical role in driving these nonequilibrium transitions. To directly couple to these domain fluctuations at ultrafast timescales requires coherent X-ray probes fo...

Gregor Humar: False vacuum decay in the transverse field Ising model ‌on a quantum annealer

This presentation deals with using quantum annealing for observing false vacuum decay in the transverse field Ising model. False vacuum decay is one of the central ideas in quantum field theory. It describes a scenario where a system in a metastable false vacuum state transitions to the true vacuum state. The transition happens by creation of bubbles of true vacuum that expand over the whole system. The timescales and the dynamics of this phenomenon are difficult to observe and describe analy...
