Atomic and Electronic Structure of Strongly Charged Domain Walls in van der Waals α-InSe
Gillian Nolan, Edmund Han, Shahriar Muhammad Nahid +4
Here, we use atomic resolution scanning transmission electron microscopy (STEM) and first principles calculations to study the atomic and electronic structure of strongly charged d…
UTe: a narrow band superconductor
Martin Sundermann, Takaki Okauchi, Naoki Ito +10
We investigate the nature of the 5 electrons in the unconventional odd-parity superconductor UTe, focusing on the degree of covalency, localization versus itinerancy, and do…
Superconducting Sn-Intercalated TaSe: Structural Diversity Obscured by Routine Characterization Techniques
Brenna C. Bierman, Gillian Nolan, Hongrui Ma +3
Using Sn-intercalated TaSe as a model system, we demonstrate the presence of structural heterogeneity captured by single-crystal X-ray diffraction (SCXRD) and scanning transmis…
Anomalous suppression of large-scale density fluctuations in classical and quantum spin liquids
Duyu Chen, Rhine Samajdar, Yang Jiao +1
Classical spin liquids (CSLs) are intriguing states of matter that do not exhibit long-range magnetic order and are characterized by an extensive ground-state degeneracy. Adding qu…
High Density Vertical Optical Interconnects for Passive Assembly
Drew Weninger, Samuel Serna, Achint Jain +2
The co-packaging of optics and electronics provides a potential path forward to achieving beyond 50 Tbps top of rack switch packages. In a co-packaged design, the scaling of bandwi…
Interplay among Work Function, electronic structure and stoichiometry in nanostructured vanadium oxides films
Alessandro D'Elia, Cinzia Cepek, Monica de Simone +6
The work function is the parameter of greatest interest in many technological applications involving charge exchange mechanisms at the interface. The possibility to produce samples…
A Near-Ideal Molecule-Based Haldane Spin-Chain
Robert C. Williams, William J. A. Blackmore, Samuel P. M. Curley +17
The molecular coordination complex NiI(3,5-lut) [where (3,5-lut) (3,5-lutidine) (CHN)] has been synthesized and characterized by several techniques includin…
Low-Temperature Dielectric Anomalies at the Mott Insulator-Metal Transition
A. Pustogow, R. Rösslhuber, Y. Tan +10
The correlation-driven Mott transition is commonly characterized by a drop in resistivity across the insulator-metal phase boundary; yet, the complex permittivity provides a deeper…
Determining the anisotropy and exchange parameters of polycrystalline spin-1 magnets
William J. A. Blackmore, Jamie Brambleby, Tom Lancaster +18
Although low-dimensional antiferromagnets remain of great interest, difficulty in obtaining high-quality single crystals of the newest materials hinders experimental resear…
Probing magnetic order and disorder in the one-dimensional molecular spin chains CuF2(pyz) and [Ln(hfac)3(boaDTDA)]n (Ln=Sm, La) using implanted muons
T. Lancaster, B. M. Huddart, R. C. Williams +9
We present the results of muon-spin relaxation (SR) measurements on antiferromagnetic and ferromagnetic spin chains. In antiferromagnetic CuF(pyz) we identify a transi…
The Many Faces of Far-from-equilibrium Thermodynamics: Deterministic Chaos, Randomness or Emergent Order?
Atanu Chatterjee, Germano Iannacchione
Far-from-equilibrium systems are ubiquitous in nature. They are also rich in terms of diversity and complexity. Therefore, it is an intellectual challenge to be able to understand…
Electron emission by long and short wavelength lasers: essentials for the design of plasmonic photocathodes
Ebrahim Forati, Dan Sievenpiper
Theory of electron emission by metallic photocathodes under the exposure of long wavelength lasers will be studied. Energy of photons in long wavelength lasers is less than the wor…
Low-temperature lattice effects in the spin-liquid candidate -(BEDT-TTF)Cu(CN)

By applying measurements of the dielectric constants and relative length changes to the dimerized molecular conductor -(BEDT-TTF)Hg(SCN)Cl, we provide evidence for order…
Quantum Spin Liquids Unveil the Genuine Mott State
A. Pustogow, M. Bories, A. Löhle +14
The Widom line identifies the locus in the phase diagram where a supercritical gas crosses over from gas-like to a more liquid-like behavior. A similar transition exists in correla…

Elena Gati, Stephen M. Winter, John A. Schlueter +3
We present high-resolution measurements of the relative length change as a function of temperature of the organic charge-transfer salt -(BEDT-TTF)Hg(SCN)Cl. We identify…
Weak ferromagnetism and glassy state in kappa-(BEDT-TTF)2Hg(SCN)2Br
