Disentangling spin polarization from driven circular ionic motion in EuTiO
Clifford J. Allington, Matthew J. Lutz, Enoch +31
Coherently driven circular ionic motion has been reported to produce large helicity-dependent optical responses attributed to transient magnetization. However, the microscopic natu…
Quantifying angular momentum of coherently driven circular phonons
Roman Mankowsky, Serhane Zerdane, Shih-Wen Huang +9
The use of intense terahertz (THz) pulses to manipulate low-energy excitations offers a powerful approach for ultrafast control of electronic and magnetic properties in materials.…
THz-induced phonon mode mixing and collective dynamics in a polar nanolattice
Elizabeth Skoropata, Peter M. Derlet, Hiroki Ueda +13
Manipulating phonons through symmetry is a fundamental approach to alter the dynamic responses of materials. Most often new phases are sought through control of the unit-cell (e.g.…
Emergent Antiphase Stacking in a Transient Charge Density Wave
Jade Stanton, Gal Orenstein, Ryan A. Duncan +14
Photoexcitation can induce novel states in materials that are inaccessible in equilibrium, a recent example being the light-induced charge density wave (CDW) observed in $\text{LaT…
Chemical and optical control of chiral-domain dynamics in 1T-TaS
Qingzheng Qiu, Mengxian Zhao, Roman Mankowsky +14
Optical control of symmetry-breaking quantum phases is often constrained when one domain is strongly favored in equilibrium. This limitation is exemplified by the chiral charge-den…
A textured polar phase in strained SrTiO3
Huaiyu Hugo Wang, Ernesto Flores, Jade Stanton +11
Quantum materials can harbour hidden phases whose microscopic structures differ from conventional ordered states while reproducing their macroscopic signatures, making them easy to…
Ultrafast Decoherence of Charge Density Waves in KMoO
Rafael T. Winkler, Larissa Boie, Yunpei Deng +20
Recent works have suggested that transient suppression of a charge density wave (CDW) by an ultra-short excitation can lead to an inversion of the CDW phase. We experimentally inve…
Dimensionality reduction of optically generated vortex strings in a charge density wave
Sajal Dahal, Alex H. Miller, Viktor Krapivin +11
In phase transitions, mesoscale structures such as topological defects, vortex strings, and domain walls control the path towards equilibrium, and thus the functional properties of…
Ultrafast surface melting of orbital order in La0.5Sr1.5MnO4
Maurizio Monti, Khalid M. Siddiqui, Daniel Perez-Salinas +12
Understanding how light modifies long-range order in quantum materials is key to improving our ability to control functionality. However, this is challenging if the response is het…
A set-up for Hard X-ray Time-resolved Resonant Inelastic X-ray Scattering at SwissFEL
Hui-Yuan Chen, Rolf B. Versteeg, Michele Puppin +15
We present a new set up for resonant inelastic hard X-ray scattering at the Bernina beamline of SwissFEL with energy, momentum, and temporal resolution. The compact R=0.5 m Johann-…
Non-equilibrium dynamics of spin-lattice coupling
Hiroki Ueda, Roman Mankowsky, Eugenio Paris +18
Interactions between the different degrees of freedom form the basis of many manifestations of intriguing physics in condensed matter. In this respect, quantifying the dynamics of…
Dynamical Scaling Reveals Topological Defects and Anomalous Evolution of a Photoinduced Phase Transition
Gal Orenstein, Ryan A. Duncan, Gilberto A. de la Pena Munoz +13
Nonequilibrium states of quantum materials can exhibit exotic properties and enable unprecedented functionality and applications. These transient states are inherently inhomogeneou…
Effect of intense x-ray free-electron laser transient gratings on the magnetic domain structure of Tm:YIG
Victor Ukleev, Max Burian, Sebastian Gliga +13
Magnetic patterns can be controlled globally using fields or spin polarized currents. In contrast, the local control of the magnetization on the nanometer length scale remains chal…

Jeremy R. Rouxel, Danny Fainozzi, Roman Mankowsky +44
Optical-domain Transient Grating (TG) spectroscopy is a versatile background-free four-wave-mixing technique used to probe vibrational, magnetic and electronic degrees of freedom i…
Ultrafast electron localization in a correlated metal
Jose R. L. Mardegan, Serhane Zerdane, Giulia Mancini +27
Ultrafast electron delocalization induced by a fs laser pulse is a well-known process and is the initial step for important applications such as fragmentation of molecules or laser…
