Universal scaling of tunable Yu-Shiba-Rusinov states across the quantum phase transition

Quantum magnetic impurities give rise to a wealth of phenomena attracting tremendous research interest in recent years. On a normal metal, magnetic impurities generate the correlation-driven Kondo effect. On a superconductor, bound states emerge inside the ...

A stochastic approach to the modelling of gas transport in bentonite

Lyesse Laloui, Aldo Madaschi

In the past years, transport of gases in clay buffer materials for Engineered Barrier Systems (EBS) has been deeply investigated by many research programs in the field of nuclear waste disposal. The phenomenological features of gas transport obtained from ...

Structure and pressure-induced ferroelectric phase transition in antiphase domain boundaries of strontium titanate from first principles

Nava Setter, Alexander Tagantsev, Alexander Kvasov

In this work, using zero kelvin ab initio calculations, we revisit the structure and ferroelectric phase transition in antiphase domain boundaries (APBs) in SrTiO3 (STO), which has been previously addressed in terms of a phenomenological approach. We confi ...

Aggregation dynamics, structure, and mechanical properties of bigels

Francesco Varrato, Giuseppe Foffi, Davide Fiocco

Recently we have introduced bigels, inter-penetrating gels made of two different colloidal species. Even if particles with simple short-range isotropic potential are employed, the selective interactions enable the tunability of the self-assembly, leading t ...

Late and early time phenomenology of Higgs-dependent cutoff

The analysis of theories with non-minimal coupling of Higgs field to gravity revealed that they enter into strong coupling regime above certain Higgs-dependent cutoff, which may be considerably below the Planck scale. Assuming that the effective theory, co ...

L'habitant et la cohabitation dans les modèles de l'espace habité

André Ourednik

The notion of habiter (inhabiting in both a transitive and intransitive sense), developed in the course of the second half of the 20th century, made it possible to place the human individual in the center of spatial theories. Of phenomenological inspiratio ...

Novel Electromechanical Phenomena at the Nanoscale: Phenomenological Theory and Atomistic Modeling

Alexander Tagantsev

In the past two decades, the fact that “small is different” has been established for a wide variety of phenomena, including electrical, optical, magnetic, and mechanical behavior of materials. However, one largely untapped but potentially very important ar ...

First-principles description of ferroelectric/electrode interfaces and properties of not very thin ferroelectric capacitors

Nava Setter, Alexander Tagantsev, Guido Gerra

We formulate an approach to the size effect problem in ferroelectric-electrode systems where ab initio calculations are combined with a phenomenological framework. The parameters of the model can be extracted from the calculations, while experimentally ver ...
