Unconventional quantum ordered and disordered states in the highly frustrated spin-1/2 Ising-Heisenberg model on triangles-in-triangles lattices

The spin-1/2 Ising-Heisenberg model on two geometrically related triangles-in-triangles lattices is exactly solved through the generalized star-triangle transformation, which establishes a rigorous mapping correspondence with the effective spin-1/2 Ising m ...

Why glass elasticity affects the thermodynamics and fragility of supercooled liquids

Matthieu Wyart

Supercooled liquids are characterized by their fragility: The slowing down of the dynamics under cooling is more sudden and the jump of specific heat at the glass transition is generally larger in fragile liquids than in strong ones. Despite the importance ...

Hydrogen trapping in delta-Pu: insights from electronic structure calculations

Michael Frederick Francis

Density functional theory calculations have been performed to provide details of the structural and charge-transfer details related to the solid solution of hydrogen in (delta)-plutonium. We follow the Flanagan model that outlines the process by which hydr ...

Simulated annealing study of the disordered quantum magnet LiHoxEryY1-x-yF4

Thermal and quantum phase transitions of some rare earth compounds (LiErF4, LiYbF4, LiGdF4 and LiTmF4) are established using the mean field theory. These preliminary calculations allowed evidencing the existence of a novel high-field antiferromagnetic phas ...

Temperature-Dependent Ordering Phenomena of a Polyiodide System in a Redox-Active Ionic Liquid

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Jan Cornelius Brauer, Verner Thorsmolle

Iodine added to iodide-based ionic liquids leads to dramatic changes of their physical properties which may have implications for technological applications. Here we study the phase diagram of 1-methyl 3-propylimidazolium iodide, the temperature versus iod ...

Observing the drop of resistance in the flow of a superfluid Fermi gas

Jean-Philippe Brantut

The ability of particles to flow with very low resistance is characteristic of superfluid and superconducting states, leading to their discovery in the past century. Although measuring the particle flow in liquid helium or superconducting materials is esse ...

Thermodynamic study and re-assessment of the Ge-Ni system

Christian Leinenbach, Robert Andrew Watson, Shan Jin

The enthalpies of formation of the intermetallic compounds in the Ge-Ni binary system have been determined by calorimetric measurement and first-principles calculations. Based on the results obtained and information available in the literature, the phase d ...

Analytical ultracentrifugation to support the development of biomaterials and biomedical devices

Jeffrey Alan Hubbell, Jutta Christine Wandrey, Conlin O'Neil, Urara Hasegawa

Analytical ultracentrifugation (AUC) primarily serves to investigate hydrodynamic and thermodynamic properties of natural and synthetic macromolecules and colloids in solution, dispersion or suspension. Beside such more conventional use, AUC can support ma ...

Experimental evidence of librational vibrations determining the stability of calcium borohydride

Pascal Martelli

The high energy of hydrogen vibrations in solids is the origin of their strong impact on thermodynamic properties. The peculiar structure of complex hydrides amplifies this impact. We shed light on the vibrational properties of three allotropes of Ca(BH4)2 ...

Supercoiling Induces Denaturation Bubbles in Circular DNA

Giovanni Dietler

We present a theoretical framework for the thermodynamic properties of supercoiling-induced denaturation bubbles in circular double-stranded DNA molecules. We explore how DNA supercoiling, ambient salt concentration, and sequence heterogeneity impact on th ...
