High School What Makes Samarium Hexaboride a Paradoxical Material?

Click For Summary
Samarium Hexaboride is a unique crystal that demonstrates contradictory properties, being conductive at room temperature and insulating below minus 223 degrees Celsius. This paradox has intrigued physicists and has led to ongoing research in the field of topological insulators. A 2015 article from Quanta Magazine highlights these unusual characteristics and their implications. Recent advancements in the study of this material suggest that further exploration could yield significant insights. The continued investigation into Samarium Hexaboride underscores its importance in understanding complex materials.

Thread 'Time rondeau crystals, experimental observations'

A relative asked me about the following article: Experimental observation of a time rondeau crystal https://www.nature.com/articles/s41567-025-03028-y I pointed my relative to following article: Scientists Discovered a Time Crystal That Reveals a New Way to Order Time https://www.yahoo.com/news/articles/scientists-discovered-time-crystal-reveals-180055389.html This area is outside of my regular experience. I'm interested in radiation effects in polycrystalline material, i.e., grain...
