Correlated vibrational coherence and spectral diffusion analysis of multi-level systems using two-dimensional electronic spectroscopy

Two-dimensional electronic spectroscopy (2DES) is used to theoretically and experimentally study a minimal three level “V” system (3LVS) with one ground state and two excited states coupled to common displaced harmonic oscillator modes. The third order non ...

Euclid IV. The NISP Calibration Unit

Frédéric Courbin, Georges Meylan

The near-infrared calibration unit (NI-CU) on board Euclid’s Near-Infrared Spectrometer and Photometer (NISP) is the first astronomical calibration lamp based on light-emitting diodes (LEDs) to be operated in space. Euclid is a mission in ESA’s Cosmic Visi ...

Ultrafast momentum-resolved visualization of the interplay between phonon-mediated scattering and plasmons in graphite

Rémi Marcel Léon Claude, Fabrizio Carbone, Thomas La Grange, Ivan Madan, Michele Puppin, Francesco Barantani, Alexey Sapozhnik, Bruce Michael Raleigh Weaver

Scattering between charges and collective modes in materials governs phenomena such as electrical resistance, energy dissipation, and phase switching. Studying such scattering requires simultaneous access to ultrafast and momentum-resolved dynamics of sing ...

The construction of large-scale structure catalogs for the Dark Energy Spectroscopic Instrument

Jiaxi Yu

We present the technical details on how large-scale structure (LSS) catalogs are constructed from redshifts measured from spectra observed by the Dark Energy Spectroscopic Instrument (DESI). The LSS catalogs provide the information needed to determine the ...

Nanocomposites Based on Thermoplastic Acrylic Resin with the Addition of Chemically Modified Multi-Walled Carbon Nanotubes

Zuzanna Dorota Krawczyk

The main goal of this work was an improvement in the mechanical and electrical properties of acrylic resin-based nanocomposites filled with chemically modified carbon nanotubes. For this purpose, the surface functionalization of multi-walled carbon nanotub ...

Complete field-induced spectral response of the spin-1/2 triangular-lattice antiferromagnet CsYbSe2

Bruce Normand, Andreas Martin Läuchli Herzig

Fifty years after Anderson's resonating valence-bond proposal, the spin-1/2 triangular-lattice Heisenberg antiferromagnet (TLHAF) remains the ultimate platform to explore highly entangled quantum spin states in proximity to magnetic order. Yb-based delafos ...

Lone Pair Rotation and Bond Heterogeneity Leading to Ultralow Thermal Conductivity in Aikinite

Virginia Carnevali

Understanding the relationship between the crystal structure, chemical bonding, and lattice dynamics is crucial for the design of materials with low thermal conductivities, which are essential in fields as diverse as thermoelectrics, thermal barrier coatin ...

Three-Dimensional Confinement of Water: H2O Exhibits Long-Range (> 50 nm) Structure while D2O Does Not

Sylvie Roke, Nathan Dupertuis, Cornelis Ulrich Lütgebaucks, Orly Bagunu Tarun

Water is the liquid of life thanks to its three-dimensional adaptive hydrogen (H)-bond network. Confinement of this network may lead to dramatic structural changes influencing chemical and physical transformations. Although confinement effects occur on a < ...

PET CMRglc mapping and H-1-MRS show altered glucose uptake and neurometabolic profiles in BDL rats

Cristina Ramona Cudalbu Moldovan, Bernard Lanz, Carole Poitry-Yamate, Dunja Simicic, Jessie Julie Mosso, Mario Gaetano Lepore, Ting Yin

Type C hepatic encephalopathy (HE) is a complex neuropsychiatric disorder occurring as a consequence of chronic liver disease. Alterations in energy metabolism have been suggested in type C HE, but in vivo studies on this matter remain sparse and have repo ...

Electronic Relaxation Dynamics of UV-Photoexcited 2-Aminopurine-Thymine Base Pairs in Watson-Crick and Hoogsteen Conformations

Rebecca Ann Ingle, Hugo Jean Baptiste Marroux

The fluorescent analogue 2-aminopurine (2AP) of the canonical nucleobase adenine (6-aminopurine) base-pairs with thymine (T) without disrupting the helical structure of DNA. It therefore finds frequent use in molecular biology for probing DNA and RNA struc ...
