-Bounded Sets
Christopher Heil, Pu-Ting Yu
A subset of a separable Hilbert space is -bounded if there exists a Riesz basis for such that $\sup_{x \in M} \sum_{n…
Convergence of frame series
Christopher Heil, Pu-Ting Yu
If is a frame for a Hilbert space then there exists a canonical dual frame such that for every we h…
Superconductivity and strong anharmonicity in novel Nb-S phases
Roman Lucrezi, Christoph Heil
In this work we explore the phase diagram of the binary Nb-S system from ambient pressures up to 250 GPa using evolutionary crystal structure prediction. We find seve…
Magnetic surface reconstruction in the van-der-Waals antiferromagnet FeTe
C. Trainer, M. Songvilay, N. Qureshi +9
FeTe is a two dimensional van der Waals antiferromagnet that becomes superconducting on anion substitution on the Te site. The parent phase of FeTe is sensitive to…
Electronic, vibrational, and electron-phonon coupling properties in SnSe and SnS under pressure
Gyanu Prasad Kafle, Christoph Heil, Hari Paudyal +1
The tin-selenide and tin-sulfide classes of materials undergo multiple structural transitions under high pressure leading to periodic lattice distortions, superconductivity, and to…
Superconductivity in sodalite-like yttrium hydride clathrates
Christoph Heil, Simone di Cataldo, Giovanni B. Bachelet +7
We report ab-initio calculations of the superconducting properties of two high-Tc sodalite-like clathrate yttrium hydrides, YH6 and YH10, within the fully anisotropic ME theory, in…
