This paper studies how atoms lose electrons when hit by very strong x‑ray light, and how the atom’s own electric pull (the Coulomb potential
Laser-plasma accelerators (LPAs) promise very large accelerating fields in a compact device. But routine operation is hard because electron-
This paper proposes a practical way to make and place topological defects — called “kinks” — in two‑dimensional Coulomb crystals of trapped
This paper shows that a long-standing numerical obstacle in quantum simulations — the fermionic sign problem in Path Integral Monte Carlo (P
What the paper proves in plain language: the authors show that, for a wide class of time-varying one-particle densities, there is a unique e
Researchers built a simulation method to test whether the physical layout of refugee and internally displaced person (IDP) camps can reduce
Researchers report the first demonstration of a frequency-degenerate twin-photon source in an integrated silicon nitride (Si3N4) microring r
This paper proposes a conceptual framework for how energy moves in collisionless plasmas. Collisionless plasmas are hot charged gases where
This paper studies how the spatial reach of interactions changes chaotic behavior in a simple, large one‑dimensional model. The authors look
This paper reviews recent progress in integrated microwave photonics, a field that uses light to generate, carry and process very high-frequ
