Negative Thermal Expansion in Cubic Ice: A Collective Quantum Effect of the hydrogen-bond network
Loan Renaud, Tomasz Poreba, Richard Gaal +3
The paper investigates why cubic ice I₍c₎ contracts when heated, showing that its negative thermal expansion arises from collective quantum behavior of the hydrogen‑bond network, c…
Displacive quantum critical point in superconducting hydrides: The case of HS
Marco Cherubini, Abhishek Raghav, Michele Casula
HS sulfur hydride has been widely investigated for its high superconducting critical temperature of 203 K at about GPa. Despite being the precursor of superco…
Spin-polaron fingerprints in the optical conductivity of iridates
Francesco Cassol, Léo Gaspard, Cyril Martins +2
As a consequence of their spin-orbit entangled ground state, many iridate materials display a peculiar double peak structure in optical transport quantities, such as absor…
Assessing many-body methods on the potential energy surface of the (H) hydrogen dimer
Damian Contant, Michele Casula, Maria Hellgren
The anisotropic potential energy surface of the (H) dimer represents a challenging problem for many-body methods. Here, we determine the potential energy curves of five dif…
