Trilayer moir茅 superlattices unlock tunable control of exciton configurations

Moir茅 superlattices are periodic patterns formed when two or more thin semiconducting layers are stacked with a small twist angle or lattice mismatch. When 2D materials form these patterns, their electronic, mechanical, ...

Mathematical 'sum of zeros' trick exposes topological magnetization in quantum materials

A new study addresses a foundational problem in the theory of driven quantum matter by extending the St艡eda formula to non-equilibrium regimes. It demonstrates that a superficially trivial "sum of zeros" encodes a universal, ...

Turbulence with a twist: New work shows fluid in a curved pipe can undergo discontinuous transition

Turbulence is everywhere, yet much about the nature of turbulence remains unknown. During the last decade, physicists have discovered how fluids in a pipe or similar geometry transition from a smooth, laminar state to a turbulent ...

JWST finds an exoplanet around A pulsar whose atmosphere is all carbon

Science advances through data that don't fit our current understanding. At least that was Thomas Kuhn's theory in his famous On the Structure of Scientific Revolutions. So scientists should welcome new data that challenges ...

Key diagnostic system for experimental fusion reactor nears completion

In the universe, thermonuclear fusion is a common reaction: it is the source of energy for stars. On Earth, producing energy using this process is difficult due to problems with controlling the plasma emitting significant ...
