Bilayer orthogonal ferromagnetism in CrTe-based van der Waals system
Chiara Bigi, Cyriack Jego, Vincent Polewczyk +19
Systems with pronounced spin anisotropy play a pivotal role in advancing magnetization switching and spin-wave generation mechanisms, which are fundamental for spintronic technolog…
Anomalous frequency scaling of acoustic phonon damping in nickel cavities fabricated by ps-laser delamination
Alba Viejo-Rodríguez, Andrea Rossetti, Marco Gandolfi +9
Single-shot picosecond (ps) laser induced delamination allows for the direct generation of suspended membranes from a continuous metallic film, offering a promising platform for co…
Photoelectron Circular Dichroism of Aqueous-Phase Alanine
Dominik Stemer, Stephan Thürmer, Florian Trinter +9
Amino acids and other small chiral molecules play key roles in biochemistry. However, in order to understand how these molecules behave in vivo, it is necessary to study them under…
Observation of a core-excited dipole-bound state 1 eV above the electron detachment threshold in cryogenically cooled acetylacetonate
Rafael A Jara-Toro, Martín Taccone, Jordan Dezalay +3
Dipole-bound states in anions exist when a polar neutral core binds an electron in a diffuse orbital through charge--dipole interaction. Electronically excited polar neutral cores…
Role of the Coulomb Potential in Compton Scattering
N. Melzer, M. Kircher, A. Pier +18
We report a fully differential study of ionization of the Ne L-shell by Compton scattering of 20 keV photons. We find two physical mechanisms which modify the Compton-electron emis…
Picocavity-Enhanced Raman Spectroscopy of Physisorbed H and D Molecules
Akitoshi Shiotari, Shuyi Liu, George Trenins +4
We report on tip-enhanced Raman spectroscopy of H2 and D2 molecules physisorbed within a plasmonic picocavity at 10 K. The intense Raman peaks resulting from the rotational and vib…
Pomeranchuk instability from electronic correlations in CsTiBi kagome metal
Chiara Bigi, Matteo Dürrnagel, Lennart Klebl +19
Among many-body instabilities in correlated quantum systems, electronic nematicity, defined by the spontaneous breaking of rotational symmetry, has emerged as a critical phenomenon…
Scattering near-field optical microscopy at 1-nm resolution using ultralow tip oscillation amplitudes
Akitoshi Shiotari, Jun Nishida, Adnan Hammud +4
Scattering-type scanning near-field optical microscopy (s-SNOM) allows for the observation of the optical response of material surfaces with a resolution far below the diffraction…
Bonding states underpinning structural transitions in IrTe observed with micro-ARPES
C. W. Nicholson, M. D. Watson, A. Pulkkinen +6
Competing interactions in low-dimensional materials can produce nearly degenerate electronic and structural phases. We investigate the staircase of structural phase transitions in…
Decoupling Many-Body Interactions in CeO2 (111) Oxygen Vacancy Structure: Insights from Machine-Learning and Cluster Expansion
Yujing Zhang, Zhong-Kang Han, Beien Zhu +7
Oxygen vacancies (VO's) are of paramount importance in influencing the properties and applications of ceria (CeO2). Yet, comprehending the distribution and nature of the VO's poses…
Sum-Frequency Generation Spectro-Microscopy in the Reststrahlen Band of Wurtzite-type Aluminum Nitride
Dorothée S. Mader, Richarda Niemann, Martin Wolf +2
Nonlinear-optical microscopy and spectroscopy provide detailed spatial and spectroscopic contrast, specifically sensitive to structural symmetry and order. Ferroics, in particular,…
Metal monoxide abundances as a function of the C/O ratio
Gerard Meijer, Gert von Helden
The diatomic metal monoxides whose optical spectra define the classification of stars on the asymptotic giant branch (AGB), that is, TiO, YO, ZrO, and LaO, have the unusual propert…
Element-specific ultrafast lattice dynamics in monolayer WSe2
H. Jung, S. Dong, D. Zahn +8
We study monolayer WSe2 using ultrafast electron diffraction. We introduce an approach to quantitatively extract atomic-site-specific information, providing an element-specific vie…
Rotating spintronic terahertz emitter optimized for microjoule pump-pulse energies and megahertz repetition rates
Alkisti Vaitsi, Vivien Sleziona, Luis E. Parra López +7
Spintronic terahertz emitters (STEs) are powerful sources of ultra-broadband single-cycle terahertz (THz) field transients. They work with any pump wavelength, and their polarity a…
Coherent Modulation of Two-Dimensional Moiré States with On-Chip THz Waves
Yiliu Li, Eric A. Arsenault, Birui Yang +11
Van der Waals (vdW) structures of two-dimensional materials host a broad range of physical phenomena. New opportunities arise if different functional layers may be remotely modulat…
Efficient All-electron Hybrid Density Functionals for Atomistic Simulations Beyond 10,000 Atoms
