Exploration of exotic quantum phase transitions has always been a focus in condensed matter physics. Critical phenomena in a phase transition are entirely determined by the universality class, which ...

Black holes are regions in space where gravity is so strong that nothing, even light, can escape. Einstein's theory of general relativity breaks down inside black holes, either by the presence of a so ...

Can we do away with the troublesome singularity at the heart of black holes? A new paper in JCAP reimagines these extreme objects in light of current knowledge. “Hic sunt leones,” remarks Stefano ...

Ever since general relativity pointed to the existence of black holes, the scientific community has been wary of one peculiar feature: the singularity at the center—a point, hidden behind the event ...

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...

Figure 1：Magnetic-field-driven superconductor-metal phase transition with multiple quantum critical points in CaFe 1-x Ni x AsF. Exploration of exotic quantum phase transitions has always been a focus ...
