Review on high-Tc superconductors at HP: Methods and Materials

I am very excited to show you my latest work that have been on parallel for over a year.  Especially, last 4-5 months have been of intense –insane– work. The number of hours invested in this work were many more that those original planned. I wish to thank to my collaborators and the great team that made of this work a very good one! I am very confident that we are presenting a solid Review, dedicated to one the hottest subjects right now.  It is worth to take a look! Search for link to arxiv below,  spread the Review !

Two hydrogen-rich materials: H3S and LaH10, synthesized at megabar pressures have revolutionized the field of superconductivity by providing a first glimpse into the solution for the hundred-year-old problem of room-temperature superconductivity. The mechanism governing these exceptional superconductors is the conventional electron-phonon coupling. Here, we describe recent advances in experimental techniques, superconductivity theory and first-principles computational methods, which made this discovery possible. The aim of this work is to provide an up-to-date compendium of the available results on superconducting hydrides and explain the synergy of different methodologies that led to the extraordinary discoveries in the field. Furthermore, in an attempt to evidence empirical rules governing superconductivity in binary hydrides under pressure, we discuss general trends in electronic structure and chemical bonding. The last part of the Review introduces possible strategies to optimize pressure and transition temperatures in conventional superconducting materials. Directions for future research in areas of theory, computational methods and high-pressure experiments are proposed, in order to advance our understanding of superconductivity.  (Link to arxiv)
