Superconducting phase diagram of multi-layer square-planar nickelates
Grace A. Pan, Dan Ferenc Segedin, Sophia F. R. TenHuisen +21
The discovery of superconductivity in square-planar nickelates has offered a rich materials platform to explore the origins of cuprate-like superconductivity. Experimental investig…
Quantum control of Hubbard excitons
D. R. Baykusheva, D. P. Carmichael, C. S. Weber +12
Quantum control of the many-body wavefunction is a central challenge in quantum materials research, as it could yield a precise control knob to manipulate emergent phenomena. Floqu…
Photo-generated charge-transfer excitons in NiO revealed by ultrafast time-resolved resonant inelastic x-ray scattering
Giacomo Merzoni, Leonardo Martinelli, Sergii Parchenko +32
Strong electronic correlation can lead to insulating behavior and to the opening of large optical gaps, even in materials with partly filled valence shells. Although the non-equili…
Magnetic excitations in NdNiO Ruddlesden-Popper nickelates observed via resonant inelastic x-ray scattering
Sophia F. R. TenHuisen, Grace A. Pan, Qi Song +16
Magnetic interactions are thought to play a key role in the properties of many unconventional superconductors, including cuprates, iron pnictides, and square-planar nickelates. Sup…
Witnessing Light-Driven Entanglement using Time-Resolved Resonant Inelastic X-Ray Scattering
Jordyn Hales, Utkarsh Bajpai, Tongtong Liu +4
Characterizing and controlling entanglement in quantum materials is crucial for the development of next-generation quantum technologies. However, defining a quantifiable figure of…
Witnessing nonequilibrium entanglement dynamics in a strongly correlated fermionic chain
Denitsa R. Baykusheva, Mona H. Kalthoff, Damian Hofmann +4
Many-body entanglement in condensed matter systems can be diagnosed from equilibrium response functions through the use of entanglement witnesses and operator-specific quantum boun…
Femtosecond photoelectron circular dichroism of chemical reactions
Vít Svoboda, Niraghatam Bhargava Ram, Denitsa Baykusheva +7
Understanding the chirality of molecular reaction pathways is essential for a broad range of fundamental and applied sciences. However, the current ability to probe chirality on th…

We report the observation of a novel nonlinear optical response from the prototypical three-dimensional topological insulator BiSe through the process of high-order harmoni…
Ultrafast renormalization of the onsite Coulomb repulsion in a cuprate superconductor
Denitsa R. Baykusheva, Hoyoung Jang, Ali A. Husain +14
Ultrafast lasers are an increasingly important tool to control and stabilize emergent phases in quantum materials. Among a variety of possible excitation protocols, a particularly…
Strong-field physics in three-dimensional topological insulators
Denitsa Baykusheva, Alexis Chacón, Dasol Kim +3
We investigate theoretically the strong-field regime of light-matter interactions in the topological-insulator class of quantum materials. In particular, we focus on the process of…

The present review addresses the technical advances and the theoretical developments to realize and rationalize attosecond-science experiments that reveal a new dynamical time scal…
Attosecond synchronization of extreme ultraviolet high harmonics from crystals
Giulio Vampa, Jian Lu, Yong Sing You +7
The interaction of strong near-infrared (NIR) laser pulses with wide-bandgap dielectrics produces high harmonics in the extreme ultraviolet (XUV) wavelength range. These observatio…
Real-time probing of chirality during a chemical reaction
Denitsa Baykusheva, Daniel Zindel, Vìt Svoboda +4
Chiral molecules interact and react differently with other chiral objects, depending on their handedness. Therefore, it is essential to understand and ultimately control the evolut…
