Orbit of a spinning compact object around a Schwarzschild black hole (left) and its projections into angular momentum aligned coordinates (right).

To describe the electron beam attenuation lengths in solids, in addition to a single-exponential law, momentum relaxation must also be taken into account.

To better understand diffusion in complex materials, a computational method separating out uncorrelated individual contributions makes it possible to construct new analytic forms for diffusivity.

Researchers use a laser to excite and precisely measure a long-sought exotic nuclear state, paving the way for precise timekeeping and ultrasensitive quantum sensing.

The interaction of Doppler-boosted light with matter at intensities approaching the Schwinger limit is explored in numerical simulations showing the creation of electron-positron pairs forming high-density relativistic attosecond jets.

Landau theory adapted to the zero spin-orbit coupling limit captures features of altermagnets, a class of colinear magnets with spin-split bands.

The radio frequency response of the Wigner crystal at low filling factors reveals the details of the pinning mode resonance and shows how this mode is affected by disorder, and which disorder is driving the frequency dependence.

3D tracking simulations show the effectiveness of a space-charge mitigation method that uses pulsed linear electron lenses to effectively increase the space charge limit in hadron synchrotrons by 50%.

Using thin layers of chiral nematic liquid crystals, researchers have observed the formation dynamics of skyrmions.

The first experimental measurement of the incoherent photonuclear production of $J/\psi$ in ultraperipheral heavy-ion collisions is better explained by the presence of subnuclear quantum fluctuations of the gluon field.

Precision measurement of the fine structure in helium makes it possible to perform an independent measurement of the fine structure constant.
