Physical Review X

The BBGKY hierarchy is generalized to systems with strong integrable contact interactions and generic long-range two-body ones, enabling the computation of experimentally measurable expectation values and correlations for classical and quantum systems.

Researchers develop a tensor-network framework using complex-time evolution to accurately compute low-lying excitation spectra of open quantum systems.

Shockwave observations resolve the high pressure structural transition and melting temperature of MgO, a critical planetary building block.

Researchers extend quantum signal processing to noncommuting control variables, enabling analytical control of hybrid oscillator-qubit quantum processors.

Extension of time-reversal-doubled axion insulators to nonsymmorphic crystals establishes a spin-resolved classification scheme and identifies mixed bismuth monohalides as candidate materials.

A theoretical framework for arbitrary-spin pyrochlore spin ice reveals that $S$ = 3/2 magnets alone switch abruptly between two distinct spin-liquid states, a transition that survives the thermal fluctuations that wash all the other transitions into crossovers.
