Imaging the Meissner effect and flux trapping in a hydride superconductor at megabar pressures using a nanoscale quantum sensor
Prabudhya Bhattacharyya, Wuhao Chen, Xiaoli Huang +24
By directly altering microscopic interactions, pressure provides a powerful tuning knob for the exploration of condensed phases and geophysical phenomena. The megabar regime repres…
Nature of the bonded-to-atomic transition in liquid silica to TPa pressures
Shuai Zhang, Miguel A. Morales, Raymond Jeanloz +3
First-principles calculations and analysis of the thermodynamic, structural, and electronic properties of liquid SiO characterize the bonded-to-atomic transition at 0.1--1.6 TP…
Model of Ramp Compression of Diamond from Ab Initio Simulations
F. González-Cataldo, B. K. Godwal, Kevin Driver +2
Ramp compression experiments characterize high-pressure states of matter at temperatures well below those present in shock compression. However, because temperature is typically no…
Phase transitions and spin-state of iron in FeO at the conditions of Earth's deep interior
E. Greenberg, R. Nazarov, A. Landa +8
Iron-bearing oxides undergo a series of pressure-induced electronic, spin and structural transitions that can cause seismic anomalies and dynamic instabilities in Earth's mantle an…
Robust block magnetism in the spin ladder compound BaFeSe under hydrostatic pressure
Shan Wu, Junjie Yin, Thomas Smart +11
The majority of the iron-based superconductors (FeSCs) exhibit a two-dimensional square lattice structure. Recent reports of pressure-induced superconductivity in the spin-ladder s…
Imaging stress and magnetism at high pressures using a nanoscale quantum sensor
S. Hsieh, P. Bhattacharyya, C. Zu +15
Pressure alters the physical, chemical and electronic properties of matter. The development of the diamond anvil cell (DAC) enables tabletop experiments to investigate a diverse la…
Theoretical and experimental evidence of a site-selective Mott transition in Fe2O3 under pressure
E. Greenberg, I. Leonov, S. Layek +6
We provide experimental and theoretical evidence for a novel type of pressure-induced insulator-metal transition characterized by site-selective delocalization of the electrons. Mö…
Pressure-Temperature Phase Diagram of Vanadium Dioxide
Yabin Chen, Shuai Zhang, Feng Ke +8
The complexity of strongly correlated electron physics in vanadium dioxide is exemplified as its rich phase diagrams of all kinds, which in turn shed light on the mechanisms behind…
Modulation calorimetry in diamond anvil cells II: Joule-heating design and prototypes
Zachary M. Geballe, Viktor V. Struzhkin, Andrew Townley +1
Part I shows that quantitative measurements of heat capacity are theoretically possible inside diamond anvil cells via high-frequency Joule heating (100 kHz to 10 MHz), opening up…
Modulation calorimetry in diamond anvil cells I: heat flow models
Zachary M. Geballe, Gilbert W. Collins, Raymond Jeanloz
Numerical simulations of heat transport in diamond anvil cells reveal a possibility for absolute measurements of specific heat via high-frequency modulation calorimetry. Such exper…
Electronic topological transitions in Cd at high pressures
Varadharajan Srinivasan, B. K. Godwal, Jeffrey C. Grossman +1
Pressure-induced changes in the Fermi surface of Cd up to 40 GPa are studied using highly accurate density-functional theory calculations. The topology of Fermi surface changes at…
Analysis of laser shock experiments on precompressed samples using a quartz reference and application to warm dense hydrogen and helium
Stephanie Brygoo, Marius Millot, Paul Loubeyre +13
Megabar (1 Mbar = 100 GPa) laser shocks on precompressed samples allow reaching unprecedented high densities and moderately high 10000-100000K temperatures. We describe here a comp…
