Thought experiments and conservation laws: Reevaluating quantum conservation principles
Credit: CC0 Public Domain Conservation laws are central to our understanding of the universe, and now scientists have expanded our understanding of these laws in quantum mechanics. A conservation law…
New insights into 2D semiconductor physics
The new technique shows remarkably good agreement with experimental results, essentially perfect at high temperature, with small discrepancies at lower temperatures. Comparison of theoretical (solid dark) and experimental (solid light)…
Tailored electron pulses for improved electron microscopy
Plots of the measured energetic fingerprints of pulsed electron beams with different electron numbers. Credit: Rudolf Haindl, Max Planck Institute for Multidisciplinary Sciences Electron microscopes provide unique vistas of nanoscale…
Uncovering the secrets of spin-orbit optical Rabi oscillations
a, The original spin-1/2 setting describing spinnings of a quantum particle in a driven magnetic field, where the spin up and spin down constitute the two-level eigenstates. b, In the…
A new way to erase quantum computer errors
While errors are normally hard to spot in quantum devices, researchers have shown that, with careful control, some errors can cause atoms to glow. Researchers used this capability to execute…
Alternative method cuts time for computer simulation of absorption spectrum from days to hour
