Precise determination of the low-energy electronuclear Hamiltonian of LiY1-xHoxF4

Sandrine Gerber, Gabriel Aeppli, Michael Müller

The insulating rare-earth magnet LiY1-xHoxF4 has received great attention because a laboratory field applied perpendicular to its crystallographic c axis converts the low-energy electronic spin Hamiltonian into the (dilute) transverse field Ising model. Th ...

Tensor network investigation of the hard-square model

Frédéric Mila, Samuel Louis Nyckees

Using the corner-transfer matrix renormalization group to contract the tensor network that describes its partition function, we investigate the nature of the phase transitions of the hard-square model, one of the exactly solved models of statistical physic ...

Lifshitz point at commensurate melting of chains of Rydberg atoms

Frédéric Mila, Natalia Chepiga

The recent investigation of chains of Rydberg atoms has brought back the problem of commensurateincommensurate transitions into the focus of current research. In two-dimensional classical systems or in one-dimensional quantum systems, the commensurate melt ...

Atomic data for the

Carmela Lardo

Context. We describe the atomic and molecular data that were used for the abundance analyses of FGK-type stars carried out within the Gaia-ESO Public Spectroscopic Survey in the years 2012 to 2019. The Gaia-ESO Survey is one among several current and futur ...

Kibble-Zurek exponent and chiral transition of the period-4 phase of Rydberg chains

Frédéric Mila, Natalia Chepiga

Chains of Rydberg atoms have emerged as an amazing playground to study quantum physics in 1D. Playing with inter-atomic distances and laser detuning, one can in particular explore the commensurate-incommensurate transition out of density waves through the ...

Liquid CO2 processing of solid polylactide foam precursors

Jan-Anders Edvin Maansson, John Christopher Plummer, Yonghoon Yoon

Diffusion of CO2 in polylactide was modelled by assuming the diffusion coefficient to depend on CO2 concentration, c, according to D[c]=D[0]exp[Ac], where D[0] and A are empirical constants, with the aim of optimizing impregnation of nominally amorphous an ...

Heat expandable biopolymers for one-step production of foam core sandwich composites

Yonghoon Yoon

The overall aim of this work has been to develop sustainable solid thermally activated foam precursors suitable for the in-line production of lightweight bio-based foam core sandwich structures with consolidated wood particle facings, using a non-inflammab ...

Planck intermediate results XXIV. Constraints on variations in fundamental constants

Julien Lesgourgues

Any variation in the fundamental physical constants, more particularly in the fine structure constant, a, or in the mass of the electron, me, affects the recombination history of the Universe and cause an imprint on the cosmic microwave background angular ...

Development and integration of high straightness flexure guiding mechanisms dedicated to the METAS watt balance Mark II

Reymond Clavel, Florent Cosandier

There is a firm will in the metrology community to redefine the kilogram in the International System of units by linking it to a fundamental physical constant. The watt balance is a promising way to link the mass unit to the Planck constant h. At the Feder ...

On the Utility of Isotopic Fine Structure Mass Spectrometry in Protein Identification

Yury Tsybin, Anton Kozhinov, Sasa Miladinovic

Modern mass spectrometry (MS)-based protein identification and characterization relies upon accurate mass measurements of the C-13 isotopic distributions of the enzymatically produced peptides. Interestingly, obtaining peptide elemental composition informa ...

The ultrafast structural response of solid parahydrogen: a complementary experimental/simulation investigation

Majed Chergui, Frank van Mourik, Luigi Bonacina

A complete characterization, based on fs pump-probe spectroscopy and mol. dynamics simulations, is presented of the ultrafast dynamics of electronic bubble formation in solid para-H2 upon impulsive excitation of impurity-doped sites, which correlate with t ...

Multiplets of free d- and f-metal ions: A systematic DFT study

Alain Borel

In this work we apply in a systematic way our multi-determinantal model to calculate the fine structure of the whole atomic multiplet manifold. The key feature of this approach is the explicit treatment of near-degeneracy correlation using ad hoc configura ...

Measurement of the running of the electromagnetic coupling at large momentum-transfer at LEP

Qian Wang, Zhirui Xu, Aurelio Bay, Liang Sun, Horst Arthur Vogel, Jian Zhao, Eduardo Sanchez

The evolution of the electromagnetic coupling, α, in the momentum-transfer range 1800 GeV2 < -Q2 < 21600 GeV2 is studied with about 40 000 Bhabha-scattering events collected with the L3 detector at LEP at centre-of-mass energies √s = 189-209 GeV. The runni ...
