High entropy oxides (HEOs) are a new class of disordered materials that exhibit great promise for a range of applications due to their enhanced structural stability. The “entropy” in an HEO originates from the random mixture of five or more metal ions sharing a single crystal lattice. These phases can only form at high temperatures, when configurational entropy can overwhelm the enthalpy of...

Most of us are familiar with ferromagnetic and antiferromagnetic materials.

Although in some cases quantum fluctuations can be strong in such systems we
would usually say that the ground state is ordered and described by a non-zero
local order parameter. In such systems, the interaction between the quantum
spins do not depend on the bond direction. Today, there is a growing class... -

Understanding the nature of the quantum spin liquids (QSL) is the holy grail of quantum condensed matter physics with a broad range of implications to other research fields. Many materials, such as the kagome lattice Heisenberg antiferromagnet (KLHA) consisting of Cu$^{2+}$ ions with spin S=1/2 arranged in a corner sharing triangle geometry, have been proposed as the model system for the QSL....
