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…
Cryogenic stabilization of molecular hydrogen in dense cubic ice
Tomasz PorÄba, Leon Andriambariarijaona, Richard Gaal +5
Hydrogen is widely regarded as a cornerstone of future low-carbon energy technologies, yet the lack of safe, efficient, and reversible solid-state storage materials remains a major…
Dual quantum locking: Dynamic coupling of hydrogen and water sublattices in hydrogen filled ice
Loan Renaud, Tomasz Poreba, Simone Di Cataldo +7
Hydrogen hydrates (HH) are a unique class of materials composed of hydrogen molecules confined within crystalline water frameworks. Among their multiple phases, the filled ice stru…
Discovery of a low-density filled-ice phase in nitrogen hydrate at high pressure
Selene Berni, Sophie Espert, Tomasz Poreba +7
We map the high-pressure phase diagram of nitrogen hydrate up to 16 GPa at room temperature by combining neutron diffraction, Raman spectroscopy, and crystal structure prediction.…
Giant splitting of the hydrogen rotational eigenenergies in the C filled ice
Simone Di Cataldo, Maria Rescigno, Lorenzo Monacelli +7
Hydrogen hydrates present a rich phase diagram influenced by both pressure and temperature, with the so-called C phase emerging prominently above 2.5 GPa. In this phase, hydrog…
