Two PRX Editorial Board members, Liuyan Zhao and Xavier Marie, talk about why PRX is positively welcoming to the field of 2D materials research.

The use of Raman sideband cooling to cool trapped polar molecules to their motional ground state sets the stage for engineering the dipole-dipole interactions of such molecules to process quantum information.

A hierarchical model of high-dimensional data reveals how deep neural networks leverage their multiple layers to reduce the data dimensionality and learn from a finite set of examples.

Given the symmetry properties of a quantum material, a new systematic framework can classify all the types of topological quantum spin liquids that can be realized in that material.

A field theory to describe systems driven out of thermal equilibrium hints at several unusual behaviors, such as time crystalline order, that could not exist in equilibrium yet can be realized rather simply.

A new technique combining magnetic resonance imaging and x-ray fluorescence can characterize, with single-neuron resolution, the presence of toxic forms of iron that might be associated with neurodegenerative diseases.

APS has selected 156 Outstanding Referees for 2024 who have demonstrated exceptional work in the assessment of manuscripts published in the Physical Review journals. A full list of the Outstanding Referees is available online.

PRX presents a collection of papers dedicated to ultrafast generation, control, and imaging of electronic dynamics in molecules and in solids—a fortuitously timed tribute to the 2023 Nobel-Prize-winning attosecond technology.

Introducing PRX’s second Perspective, Igor Mazin, PRX’s Editorial Board member, and the editors offer their take on why altermagnetism is needed to describe a new class of magnetism.
