The thermal conductivities of materials are extremely important for many practical
applications, such as in understanding the thermal balance and history of the Earth, energy …

Matter at extreme temperatures and pressures—commonly known as warm dense matter
(WDM)—is ubiquitous throughout our Universe and occurs in astrophysical objects such as …

Warm dense matter (WDM)—an exotic state of highly compressed matter—has attracted
increased interest in recent years in astrophysics and for dense laboratory systems. At the …

Two or more liquid states may exist even for single-component substances, which is known
as liquid polymorphism, and the transition between them is called liquid–liquid transition …

Hydrogen, the simplest and most abundant element in the Universe, develops a remarkably
complex behaviour upon compression. Since Wigner predicted the dissociation and …

Observations of Jupiter's gravity field by Juno have revealed surprisingly low values for the
high-order gravitational moments, considering the abundances of heavy elements …
