Thermodynamic anomaly above the superconducting critical temperature in the quasi-one-dimensional superconductorTa4Pd3Te16

We study the intrinsic electronic anisotropy and fermiology of the quasi-one-dimensional superconductor Ta4Pd3Te16. Below T∗=20 K, we detect a thermodynamic phase transition that predominantly affects the conductivity perpendicular to the quasi-one-dimensi ...

Electronic in-plane symmetry breaking at field-tuned quantum criticality in CeRhIn5

Philip Johannes Walter Moll, Maja Deborah Bachmann, Kent Robert Shirer

Electronic nematic materials are characterized by a lowered symmetry of the electronic system compared to the underlying lattice, in analogy to the directional alignment without translational order in nematic liquid crystals1. Such nematic phases appear in ...

Soft actuation and sensing towards robot-assisted facial rehabilitation

Jamie Paik, Amir Firouzeh

Continuing research efforts in robot-assisted rehabilitation demand more adaptable and inherently soft wearable devices. A wearable rehabilitative device is required to follow the motion of the body and to provide assistive or corrective motions to restore ...

Numerical experiments for multiscale problems in linear elasticity

Assyr Abdulle

This paper gives numerical experiments for the Finite Element Heterogeneous Multiscale Method applied to problems in linear elasticity, which has been analyzed in [A. Abdulle, Math. Models Methods Appl. Sci. 16, 2006]. The main results for the FE-HMM a pri ...

Measurement of the penetration depth and coherence length of MgB2 in all directions using transmission electron microscopy

Janusz Andrzej Karpinski

We demonstrate that images of flux vortices in a superconductor taken with a transmission electron microscope can be used to measure the penetration depth and coherence length in all directions at the same temperature and magnetic field. This is particular ...

Spin-fluctuation mediated superconductivity and magnetic order in the cuprate La1.88Sr0.12CuO4

High-temperature superconductivity in cuprates emerges as one out of many electronic phases when doping the antiferromagnetic Mott insulator La2CuO4 away from half lling. The description of the superconducting phase is therefore complicated by intertwined ...

Tuning electronic correlations in transition metal pnictides: Chemistry beyond the valence count

Thorsten Schmitt, Joël Mesot, Elia Razzoli, Philipp Aebi

The effects of electron-electron correlations on the low-energy electronic structure and their relationship with unconventional superconductivity are central aspects in the research on iron-based pnictide superconductors. Here we use soft x-ray angle-resol ...

The Interplay Between Structural and Electronic Degrees of Freedom in Superconductors

Mathieu Julien Gino Cottet

More than one hundred years after the discovery of superconductivity in Leiden, the intriguing physics of several unconventional classes of superconductors continue to fascinate and challenge scientists from all over the world. The majority of these compou ...

Irreversible Degradation in Nb3Sn Cable in Conduit Conductors

Ciro Calzolaio

One of the biggest goals for the international thermonuclear experimental reactor (ITER) is the steady state operation. For this reason all its coils will be superconducting and Nb3Sn material is used for both the toroidal field (TF) and the central soleno ...

Band structure effects on the superconductivity in Hubbard models

Ronny Thomale

We study the influence of the band structure on the symmetry and superconducting transition temperature in the (solvable) weak-coupling limit of the repulsive Hubbard model. Among other results we find that (1) as a function of increasing nematicity, start ...
