Origin of Flat Bands and Role of Electron Correlation in Lutetium Hydrides
Anmol Lamichhane, Adam Denchfield, Hyeondeok Shin +3
Lutetium hydrides (LuH, ) form a diverse series of phases, several of which superconduct under pressure. Characterizing their electronic properties has rema…
Evidence for superconductivity at 190 K in a pressure-overdoped cuprate
Alexander C. Mark, Huu T. Do, David Rodriguez +6
It is well established that the critical temperature () of cuprate superconductors can be tuned by pressure. For example, compression decouples the hole doping from chemical d…
Amorphous High Density Plutonium
J. K. Katz, A. Rollett, R. J. Hemley
Metastable aluminum-alloyed -plutonium shrinks rapidly and pure -plutonium swells rapidly at 4 K. At ambient temperature alloyed -plutonium swells about as fast…
Interface-dependent Phase Transitions and Ultrafast Hydrogen Superionic Diffusion of H2O Ice
Pengfei Hou, Yumiao Tian, Zifeng Liu +5
High-pressure experiments using diamond anvils have revealed novel properties and phase behavior of H2O under extreme conditions. When contained in diamond-anvil cells, the H2O sam…
Novel Transformations of PbTiO3 with Pressure and Temperature
Husam Farraj, Stefano Racioppi, Gaston Garbarino +8
We investigated the behavior of lead titanate (PbTiO3) up to 100 GPa, both at room temperature and upon laser heating, using synchrotron X ray diffraction combined with density fun…
Stability and Structure of Binary Metal Hydrides under Pressure, Electrochemical Potential and Combined Pressure-Electrochemistry
Mgcini Keith Phuthi, Pin-Wen Guan, Russell J. Hemley +1
Metal hydrides can be tuned to have a diverse range of properties and find applications in hydrogen storage and superconductivity. Finding methods to control the synthesis of hydri…
X-ray Diffraction and Electrical Transport Imaging of Superconducting Superhydride (La,Y)H10
Abdul Haseeb Manayil Marathamkottil, Kui Wang, Nilesh P. Salke +9
We report the synthesis and characterization of (La0.9Y0.1)H10 superhydrides exhibiting coexisting cubic Fm-3m and hexagonal P63/mmc clathrate phases observed over the pressure ran…
Pressure tuning of competing interactions on a honeycomb lattice
Piyush Sakrikar, Bin Shen, Eduardo H. T. Poldi +20
Magnetic exchange interactions are mediated via orbital overlaps across chemical bonds. Thus, modifying the bond angles by physical pressure or strain can tune the relative strengt…
Pressure tuning of Kitaev spin liquid candidate NaCoSbO
E. H. T. Poldi, R. Tartaglia, G. Fabbris +17
The search for Kitaev's quantum spin liquid (KQSL) state in real materials has recently expanded with the prediction that honeycomb lattices of divalent, high-spin cobalt ions coul…
Creation, stabilization, and study at ambient pressure of pressure-induced superconductivity in BiSbTe
Liangzi Deng, Busheng Wang, Clayton Halbert +13
In light of breakthroughs in superconductivity under high pressure, and considering that record critical temperatures (Ts) across various systems have been achieved under high…
Non-bulk Superconductivity in PrNiO Single Crystals Under Pressure
Xinglong Chen, E. H. T. Poldi, Shuyuan Huyan +8
Magneto-transport measurements of PrNiO single crystals performed under externally applied pressures up to 73 GPa in diamond anvil cells with either KBr or Nujol oil…
Correlation Effects on Coupled Electronic and Structural Properties of Doped Rare-Earth Trihydrides
Adam Denchfield, Hyeondeok Shin, Panchapakesan Ganesh +2
Rare-earth trihydrides (H) exhibit intriguing coupled electronic and structural properties as a function of doping, hydrogen vacancies, and thermodynamic conditions. Theoret…
