This is an especially interesting research direction in magnetism\, where the coupling between spin and lattice excitations is required for magnetization reversal [3]. Despite several attempts [4\,5] however\, the switching between magnetic states via resonant pumping of phonon modes has not yet been demonstrated. \nTo provide resonant excitation of the phonon modes\, we use pulses from FELIX (Free Electron Lasers for Infrared eXperiments\, Nijmegen\, The Netherlands). The IR/THz light with photon energy ranging between 25 meV and 124 meV (wavelength 10-50 μm) is typically focused onto the sample. The pulses of FELIX have been shown to be Fourier-transform limited [6]\, with their bandwidth experimentally tunable in the range of 0.5-2.0%\, corresponding to the typical pulse width of 1-10 ps\, depending on the wavelength range. \nAnd thus we show how an ultrafast resonant excitation of the longitudinal optical phonon modes in magnetic garnet films switches magnetization into a peculiar quadrupolar magnetic domain pattern\, unambiguously revealing the magneto-elastic mechanism of the switching [7]. In contrast\, the excitation of strongly absorbing transverse phonon modes results in thermal demagnetization effect only. The mechanism appears to be very universal\, and is shown to work in samples with very different crystallographic symmetry and magnetic properties. \n\nT. Kubacka et al.

While the absence of stray fields\, the insensitivity to external magnetic fields and ultra-fast dynamics make antiferromagnets promising candidates for active elements in spintronic devices\, optical control has been limited to a few insulating antiferromagnets with specific spin configurations at cryogenic temperatures.4\,5 Here\, we demonstrate optical manipulation of the staggered magnetization in the metallic collinear antiferromagnet Mn2Au by combining tensile strain and excitation with femtosecond optical pulses at room temperature. By applying tensile strain along one of the two orthogonal in-plane easy axes and exciting the sample at room temperature by a train of intense femtosecond pulses\, we are able to manipulate the direction of the Néel vector\, resulting in a stable magnetically aligned state. The dependence of optically induced Néel vector alignment on excitation density and strain suggests the alignment is a result of induced depinning of 90° domain walls and their montion in the direction of the free-energy gradient\, governed by the magneto-elastic energy. Such an approach may be applicable to a wider range of collinear antiferromagnets. \n\nKimel\, A. et al. Nature 435\, 655–657 (2005).\nKhorsand\, A. R. et al.\, Phys. Rev.

Carl Friedrich Gauss 3\, 08860 Castelldefels (Barcelona)\, Spain \nOur recent numerical results on many-body localization in disordered and quasiperiodic spin chains will be presented. The time dynamics in 1D disordered Heisenberg spin-1/2 chain is studied focusing on a regime of large system sizes and a long time evolution. Performing extensive numerical simulations of the imbalance\, a quantity often employed in the experimental studies of MBL\, we show that the regime of a slow power-law decay of imbalance persists to disorder strengths exceeding by at least a factor of 2 the current estimates of the critical disorder strength for MBL. Even though we investigate time evolution up to few thousands tunneling times\, we observe no signs of the saturation of imbalance that would suggest freezing of system dynamics and provide a smoking gun evidence of MBL. We demonstrate that the situation is qualitatively different when the disorder is replaced by a quasiperiodic potential. In this case\, we observe an emergence of a pattern of oscillations of the imbalance that is stable with respect to changes in the system size. This suggests that the dynamics of quasiperiodic systems remain fully local at the longest time scales we reach provided that the quasiperiodic potential is sufficiently strong. The results for time dynamics are further confirmed by a finite-size scaling analysis of eigenstates and spectral statistics across the many-body localization in quasiperiodic systems. The analysis shows the many-body localization transition in quasiperiodic systems belongs to the Berezinskii-Kosterlitz-Thouless class\, the same as in the case of uniformly disordered systems. However\, the finite size effects are less severe in quasiperiodic systems than in chains with random disorder. Also interestingly\, deep in the ergodic regime\, we find an unexpected double-peak structure of distribution of onsite magnetizations. Our studies identifies challenges in an unequivocal experimental observation of the phenomenon of MBL [1\,2]. \nThe numerical calculations have been possible thanks to PL-Grid Infrastructure.

Carl Friedrich Gauss 3\, 08860 Castelldefels (Barcelona)\, Spain \n2The Abdus Salam International Center for Theoretical Physics\, Strada Costiera 11\, 34151\, Trieste\, Italy \n3JEIP\, USR 3573 CNRS\, Collège de France\, PSL Research University\, 11 Place Marcelin Berthelot\, 75321 Paris Cedex 05\, France \nThe competition between unitary evolution that spreads information throughout the manybody system\, and the monitoring action of an environment gives rise to dynamical phases separated by measurement-induced phase transitions. The first part of the talk will be devoted to numerical investigations of the structure of many-body wave functions of 1D random quantum circuits with local measurements across a measurement-induced transition between phases with volume-law and area-law scaling of entanglement entropy. The many-body wave functions are investigated by means of the participation entropies. The leading term in system size dependence of participation entropies indicates a multifractal scaling of the wavefunctions at any non-zero measurement rate. The sub-leading term contains universal information about measurement-induced phase transitions and plays the role of an order parameter\, being non-zero in the volume-law phase and vanishing in the area-law phase. We provide an analytical interpretation of this behavior expressing the participation entropy in terms of partition functions of classical statistical models in 2D. The second part of the talk will concern the structure of many-body wave functions in systems that undergo localization transitions – both in presence and in absence of interactions. The ensuing measures of localization in the system alongside with the more conventional quantities will be used to discuss the stability of many-body localization in the Kicked Ising model. \n\nP.

Due to the irrelevance of electron-electron correlations in these systems\, the same hydrogenic excitonic models apply to many material classes. In Mott insulators\, however\, strong interactions between electronic\, spin\, and orbital degrees of freedom create pathways for other excitonic binding mechanisms. These so-called Hubbard excitons are predicted to exhibit novel non-hydrogenic properties that rely critically on the microscopic description of the host material. I will report the spectroscopic signatures of transient exciton formation in the antiferromagnetic spin-orbital Mott insulator Sr2IrO4 obtained by employing an ultrafast terahertz probe that is sensitive to transitions between different excitonic states. A near-infrared photoexcitation is used to generate a conductive particle-hole gas\, which decays into insulating excitonic states. Strong spin-exciton coupling is deduced from an analysis of the excitonic recombination dynamics as a function of temperature. To develop a microscopic picture of the excitonic states\, I will compare the experimental results against numerical exact diagonalization calculations. These results stimulate the search for novel excitonic states in other Mott insulating systems.

Dissipative phase transitions in steady states of time-independent Liouvillians and measurement induced phase transitions at the level of quantum trajectories are two primary examples of such transitions. Investigating a many-body spin system subject to periodic resetting measurements\, we argue that many-body dissipative Floquet dynamics provides a natural framework to analyze both types of transitions. We show that a dissipative phase transition between a ferromagnetic ordered phase and a paramagnetic disordered phase emerges for long-range systems as a function of measurement probabilities. A measurement induced transition of the entanglement entropy between volume law scaling and area law scaling is also present\, and is distinct from the ordering transition. The ferromagnetic phase is lost for short range interactions\, while the volume law phase of the entanglement is enhanced. An analysis of multifractal properties of wave function in Hilbert space provides a common perspective on both types of transitions in the system. Our findings are immediately relevant to trapped ion experiments\, for which we detail a blueprint proposal based on currently available platforms. \n\nP. Sierant\, G.
