This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

From keepsakes to indulgences, explore refined Valentine’s Day gifts that celebrate love with style, intention and timeless ...

Researchers at Massachusetts Institute of Technology have demonstrated a surprising new way to compute—by using heat instead of electricity. In a proof-of-concept study published in Physical Review ...

Essentially, the quantum metric creates a “geometric” drag on the electrons. When the magnetic field is applied, it breaks the time-reversal symmetry, revealing this hidden geometry by causing the ...

Physicists have directly mapped a hidden kind of geometry inside quantum materials that steers electrons in ways strikingly ...

They combined optical tweezers with metasurfaces to trap more than 1,000 atoms, with the potential to capture hundreds of thousands more. Quantum computers will only surpass classical machines if they ...
