Stacking-Dependent Magnetism and Tunable Half-Metallicity in Bilayer Janus 1T-MnSSe
Jakkapat Seeyangnok, Udomsilp Pinsook, Graeme J. Ackland
We investigate the structural, electronic, and magnetic properties of bilayer Janus 1T-MnSSe using first-principles calculations. Various AA- and AB-type stacking configurations ar…
Triangular Charge-Density Waves (T-CDW) Stabilize Janus Group-VI Chalcogenide Hydrides
Jakkapat Seeyangnok, Udomsilp Pinsook, Graeme J. Ackland
Hydrogenation is an effective strategy for enhancing electron--phonon coupling (EPC) and superconductivity in two-dimensional materials. However, excessively strong EPC can also in…
Noble-Gas Solubility in Solid and Fluid Metallic Hydrogen
Jakkapat Seeyangnok, Udomsilp Pinsook, Graeme J Ackland
Metallic hydrogen dominates the deep interiors of giant planets, where trace elements interact with dense quantum matter under extreme pressure. We investigate the thermodynamic st…
Frustrated supermolecules: the high-pressure phases of crystalline methane
Marcin Kirsz, Miguel Martinez-Canales, Ayobami D. Daramola +3
Methane is the simplest hydrocarbon, yet it exhibits an extraordinarily complicated series of crystal phases. Notably, the non-plastic phases have large unit cells with nearly, but…
Competition between Charge Density Wave and Superconductivity in a Janus MXene Mo2NF2
Jakkapat Seeyangnok, Udomsilp Pinsook, Graeme J Ackland
Charge-density-wave (CDW) order and superconductivity often compete in low-dimensional materials, yet their interplay in Janus MXenes remains largely unexplored. Here, we present a…
Enhanced Electron-Phonon Coupling and Superconductivity in Ba-Alloyed A15 LaH5.75
Jakkapat Seeyangnok, Udomsilp Pinsook, Graeme J Ackland
Recent experiments have established rare earth A15 type hydrides as a distinct family of high temperature superconductors that can be stabilized at significantly lower pressures co…
