Mean field magnetism and spin frustration in a double perovskite oxide with compositional complexity
Nandana Bhattacharya, Ravi Kiran Dokala, Sourav Chowdhury +9
The rise of high-entropy oxides as a major functional materials design principle in recent years has prompted us to investigate how compositional disorder affects long-range magnet…
Orbital-lattice coupling and polaronic dressing of electronic states in PrCaMnO revealed by ultrafast broadband spectroscopy
Emmanuel B. Amuah, Khalid M. Siddiqui, Maurizio Monti +6
The interplay between long-range structural distortions and orbital order, and local short-range phenomena such as polarons, are key for understanding the properties of the mangani…
A versatile setup for symmetry-resolved ultrafast dynamics of quantum materials
Khalid M. Siddiqui, Hanna Strojecka, Thomas H. Meyland +4
Correlated phenomena occur in quantum materials because of the delicate interplay between internal degrees of freedom, leading to multiple symmetry-broken quantum phases. Resolving…
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…
Ultrafast X-ray imaging of the light-induced phase transition in VO2
Allan S. Johnson, Daniel Pérez-Salinas, Khalid M. Siddiqui +26
Using light to control transient phases in quantum materials is an emerging route to engineer new properties and functionality, with both thermal and non-thermal phases observed ou…
Multi-mode excitation drives disorder during the ultrafast melting of a C4-symmetry-broken phase
Daniel Perez-Salinas, Allan S. Johnson, Dharmalingam Prabhakaran +1
Spontaneous C4-symmetry breaking phases are ubiquitous in layered quantum materials, and often compete with other phases such as superconductivity. Preferential suppression of the…
Mapping nanoscale charge states and phase domains with quantitative hyperspectral coherent diffractive imaging spectroscopy
Allan S. Johnson, Jordi Valls Conesa, Luciana Vidas +7
The critical properties of functional materials and nanoscale devices often originate from the coexistence of different thermodynamic phases and / or oxidization states, but sample…
Study of second and third harmonic generation from an indium tin oxide nanolayer: influence of nonlocal effects and hot electrons
Laura Rodriguez-Sune, Michael Scalora, Allan Johnson +6
We report comparative experimental and theoretical studies of second and third harmonic generation from a 20nm-thick indium tin oxide layer in proximity of the epsilon-near-zero co…
Does VO Host a Transient Monoclinic Metallic Phase?
Luciana Vidas, Daniel Schick, Elías Martínez +8
Ultrafast phase transitions induced by femtosecond light pulses present a new opportunity for manipulating the properties of materials. Understanding how these transient states are…
Nanoscale spectroscopic imaging of phase separation in a correlated material by resonant X-ray holography
Luciana Vidas, Christian M. Günther, Timothy A. Miller +8
Nanoscale phase coexistence and inhomogeneity are ubiquitous in correlated electron materials, existing in doped Mott insulators, manganites, and high-temperature superconductors.…
