Two world maps showing predicted (top) and observed (bottom) surface air temperature change. Below them both is a color scale from blue (−0.6°C) through yellow (0°C) to dark red (1.2°C). The top map, labeled "Model," uses orange shading across most of the globe, with contour lines and numerical labels indicating warming of +1 to +5°C. Warming is strongest, indicated in deep orange from +4 to +5°C, at high northern latitudes and weakest near the Southern Ocean, where a small blue patch indicates near-zero or slight cooling. The bottom map, labeled "Observations," shows similar warming across most land and ocean areas, with cooling (blue) concentrated around the Southern Ocean and parts of Antarctica.

The flow passes through four stacked regions that transition from purple at the top to red at the bottom and are separated by horizontal dashed lines. The top box is labeled SMEFT and displays Dimension-6, 8 vs. Dimension-5, 7 operators, with RG Running annotations. Below is LEFT with Dimension-6, 7, 8 vs. Dimension-3, 6, 7 neutrino-quark interactions. Below is X PT with nucleon and pion processes. On the bottom is the nuclear response, where both paths combine into a box with operators MJ, delta J, Sigma’ J, Sigma’’ J, Phi’ J, and Phi’’ J. An arrow leads to the cross section region at the bottom, featuring the formula dσ/dT_nr = (m_A / 8πE_ν²) |M|².

Dispersive readout couples qubits to environmental defects, causing lifetime degradation. A study in PRX Quantum develops a way to predict the strength of this coupling and mitigate the degradation. Read the study: go.aps.org/3TDCnlE

A schematic shows how the readout resonator couples to a qubit in an environmental bath. The environmental bath is connected to a qubit — represented by a blue rectangle — on the left. The qubit is then connected to the resonator — a purple oval — and a readout pulse.

Using a multi-scale validation strategy to probe nuclear octupole deformation and its quantum fluctuations, researchers show that event-by-event fluctuation directly correlates with octupole quantum-shape fluctuation. Read the paper in Physical Review C: go.aps.org/4hdFDfn

A schematic illustration of a heavy-ion collision involving nuclei with octupole deformation. Three images on the left side depict representative reaction snapshots viewed along the y axis; from top to bottom these are 0 fm/c, 3 fm/c, and 10 fm/c. The image on the right shows the emission pattern at T = 10 fm/c viewed along the beam axis. An inset image in the lower right corner is labeled initial overlap and shows the initial transverse density overlap. It depicts the z-integrated baryon density of participant matter at T = 0 fm/c.

A method lets scientists characterize a quantum system using the fewest measurements possible. Tested on a silicon chip for a 6D system, it works without special measurement tools and could make quantum experiments more efficient. More in Physical Review A: go.aps.org/3URgtfd

A schematic of a silicon photonic chip used for quantum state tomography. At the top, laser light passes through optical components into the chip, where the quantum states are prepared and measured. At the bottom, an enlarged view of the chip shows three sections: a single-photon generation in a spiral waveguide, preparation of six-dimensional quantum states using interconnected Mach-Zehnder interferometers, and measurement in seven different bases. The setup collects the measurement data and processes it to reconstruct the quantum state. The seven bases are the minimum number needed to fully characterize a six-dimensional quantum state.

New in PRX Energy: A comparison of common fast cycling test protocols with four EV battery chemistries reveal that performance, operational range, and degradation during cycling was highly dependent on the protocols used. Read the paper: go.aps.org/4hxns5F

A graph shows the voltage profiles of a battery cell during a 10C symmetric cycling protocol. Lines showing anode (blue), cathode (red) and cell (black) energies are plotted as voltage versus capacity. The lines for a right-facing horseshoe shape with blue at the bottom and red and black mirrored at the top. An inset image in the top right shows an image of the anode from the cell in a charged state.

Quantum batteries suffer from fluctuations that limit their ability to meet the energy needs of quantum technology. A study in PRX Quantum identifies a tradeoff between work and power that prevents them from being simultaneously enhanced. Read the paper: go.aps.org/4ht4ux1

A schematic that demonstrates the inverse relationship between power and work in quantum batteries. An arrow at the top indicates charging power increases from the left to the right of the image. A green battery with an atom icon is at the center. On either side of the battery, there is a green dial representing delivered power, and a red dial representing work. On the left, the power meter is reliable, while the work meter shows significant fluctuation. On the right, both dials are higher, but the power meter shows significant variability while the work meter is more stable.

⚛️ A new Physical Review C theoretical study solves a puzzle about nuclear scission and fragment-spin generation, offering new techniques for microscopic rotating fission. The bending scission mode dominates at low energies, but modes are mixed at high energies. 🔗 go.aps.org/4cMOYJR

Illustration of FF spin SL/H of a rotating compound nuclei–shown as a grey peanut shape with two lobes. The x-, y- and z-axes are drawn through the compound, in purple, with angular momentum LCN depicted by a curved grey arrow, rotating clockwise around the y-axis. Each lobe has two arrows (one light blue and one red) emanating from it, parallel to the y-axis. Light blue axes are labeled SL and SH for the leftmost (light) lobe and the rightmost (heavy) lobe respectively. Inherited spins are denoted by SrL and SrH for the light and heavy fragments, respectively.

Defects and asymmetries can drive information through quantum systems, generating long-range entanglement, according to a new study published in Physical Review Research. The findings offer a new way to understand quantum information transport. 📄 go.aps.org/4A6JnIa

Six panels marked a–f showing information currents in a seven-site quantum chain for different combinations of particle-hole asymmetry and a site detect. Arrows in each show the direction of information flow, while color indicates its strength. The panels show a clean symmetric chain, particle-hole asymmetry, a site defect, asymmetry with a defect, weak asymmetry, and weak asymmetry with a defect, respectively. In a clean, symmetric chain, currents within the information lattice are largely suppressed; asymmetry or a defect enables information to flow through the system.
