Pressure induced color change and evolution of metallic behavior in nitrogen-doped lutetium hydride
By applying pressures up to 42 GPa on the nitrogen-doped lutetium hydride (LuH 2+ x N y ), we have found a gradual change of color from dark-blue to...

Color
Color is fundamentally about the perception of light by our eyes and brains. This perception starts with light entering our eyes and getting focused... -
Color Conservation, Color Rotations, and \(\textrm{SU}(N)\) Irreducible Representations
After defining color conservation, we discuss \(\textrm{SU}(N)\)... -
Pressure-induced color change arising from transformation between intra- and inter-band transitions in LuH2±xNy
The pressure-induced color change in the nitrogen-doped lutetium hydride has triggered extensive discussions about the underlying physics and...
