Resolving the open controversies on the anomalous #superconducting trends in metastable phases of #Phosphorus

Among elemental compounds, the high-pressure superconducting phase diagram of phosphorus is one of the most complex. In this work, we measured electrical resistivity and performed ab initio superconductivity calculations in order to solve, for the first time the open controversies on the anomalous superconducting trends. Our work forms on a single picture a consistent scenario …

Layered binaries as candidates for hard-magnets

For the most recent work on hard-magnetic systems we focused in binaries stacked layers of FePt, MnAl and MnGa. In this work an enhancement of the  mangetocrystalline  anisotropy was calculated for specially stacked structures. After a long search and great effort of the wonderful team of collaborators (special thanks and all the credit goes to …

Piz Daint 3rd fastest supercomputer

The supercomputer ranking published on 19 June 2017, places Switzerland’s 19.6 petaflop Piz Daint supercomputer third in the world after Sunway TaihuLight and Tianhe 2, two Chinese supercomputers. Piz Daint’s recent upgrades allowed it to climb five positions up the ranking. With a performance of 93 petaflops, China’s TaihuLight is by far the most powerful number-cruncher …

Cornell 2017: Hoffmann, Ashcroft, Mermin

During my days in Ithaca (Cornell University), I had the great opportunity to show part of my research work. I decided to present the research I had just finished at that time about the possibility to induce a metallic state in ice under pressure and upon doping; thinking that I could attract more attention and …

Computing allocation in CSCS granted for my project !

Our first computing grant was just accepted by the CSCS! Last year I submitted a project requesting for 700 thousand computing nodes hours to run an exploration over hundreds of molecules. These systems are candidates to test under pressure, and upon doping for the potential to become high temperature superconductors. Last march 24th (2017) our …

The elephant in the room of density-functional theory calculations

While basis set convergence sounds straightforward (though time-consuming) it is hard to rule out that underlying assumptions in  the design of the basis set influences the results.  However, converged basis set DFT results are needed to separate basis set errors from errors due to the functional. Multiwavelets, a systematic and adaptive multiresolution numerical solution of the …

H2O ice as superconductor? yes, superconducting water !

We have recently investigated the possibility of achieve high-temperature superconductivity in hydrides under pressure by inducing metallization of otherwise insulating phases through doping, a path previously used to render standard semiconductors superconducting at ambient pressure. Following this idea, we study HO, which is one of the most abundant and well-studied substances in the universe! We …

Lindau Nobel Laureate Physics Meeting 2016

Probably one of the most excited week of my life. For many reasons and in many contexts that week in Lindau was simply: magical. After the semester ends, and with new projects in hands, with two nice papers ready to submit, summer that knocks the door, and personally ready to turn on the page.  All …

First Superhydrides meeting in Rome

In past May (2016) I attended the first edition of the International Workshop in “Superhydrides  Towards Room Temperature Superconductivity: Hydrides and More” . This was a very important meeting because it gathers the world-wide experts (experimentalists and theoreticians) in this matter. The urgent of the meeting was motivated by the 200 K superconductivity discovered only …

International collaboration demonstrates reliability of quantum simulations for materials design

An international collaboration with colleagues from over 30 universities and institutes to investigated to what extent quantum simulations of material properties agree when they are performed by different researchers and with different software. Thanks to an online collaboration, they successfully demonstrated that the most recent generations of codes agree well, in contrast to earlier generations. …
