Making superconductors thinner can change how they accommodate magnetic fields

|

Conceptual illustration of how reducing the thickness of a superconducting film can change its magnetic response. A thicker film tends to exclude magnetic fields, while in a thinner film magnetic flux can penetrate in the form of quantized vortices. The effect reflects the changing balance between superconducting coherence and magnetic penetration as quantum confinement becomes more important.

When less is more: Scaling law explains why ultrathin materials get stronger as they get thinner

Credit: Created by Alessio Zaccone using AI-assisted tools One of the most fascinating aspects of physics is that nature often behaves in ways that seem completely counterintuitive. A good example comes from ultrathin materials. If I take a sheet of material and make it thinner and thinner, most people would expect it to become weaker. After all, there is less material left to bear a load.

New mathematical model predicts global population crash by 2064

|

| Phys.org Verified
In a new open-access study that I published with my late colleague Kostya Trachenko from Queen Mary University of London, I propose a surprisingly simple nonlinear mathematical equation that unifies 12,000 years of human population growth and points to stark possible futures if global environmental crises intensify.
