Strategy of Sintering Ceramics Under Extreme Conditions

Interdisciplinary Materials, Volume 5, Issue 2, Page 243-251, March 2026.
Novel strategies in extreme sintering technologies, which include ultrafast sintering, strong electric field‐assisted sintering, high‐pressure and ultra‐high‐pressure sintering, and multi‐field assisted sintering, and so on. ABSTRACT Advanced ceramics play a critical role in high‐tech industries.

Dirac's "magnetic monopole" in pyrochlore ice U(1) spin liquids: Spectrum and classification

, 2017
We study the U(1) quantum spin liquid on the pyrochlore spin ice systems. For the non-Kramers doublets such as Pr$^{3+}$ and Tb$^{3+}$, we point out that the inelastic neutron scattering not only detects the low-energy gauge photon, but also contains the

Structural Determination, Oxygen Diffusion, and Storage Capacity of a High‐Entropy Fluorite‐Type Oxidation Catalyst

Small Structures, Volume 7, Issue 3, March 2026.
Inducing cationic high entropy on CeO2 modifies the structure, leading to increased oxygen diffusion and resistance to sintering. In turn, this leads to enhanced oxygen storage capacities without degradation, showing potential for oxidation catalysis.

Pyrochlore Photons: The U(1) Spin Liquid in a S=1/2 Three-Dimensional Frustrated Magnet

, 2003
We study the S=1/2 Heisenberg antiferromagnet on the pyrochlore lattice in the limit of strong easy-axis exchange anisotropy. We find, using only standard techniques of degenerate perturbation theory, that the model has a U(1) gauge symmetry generated by

Order Induced by Dilution in Pyrochlore XY Antiferromagnets

, 2014
XY pyrochlore antiferromagnets are well-known to exhibit order-by-disorder through both quantum and thermal selection. In this paper we consider the effect of substituting non-magnetic ions onto the magnetic sites in a pyrochlore XY model with generally ...
