Researchers use the S-matrix bootstrap to examine whether string theory is the only consistent theory of quantum gravity

The S-matrix bootstrap is a numerical method that can be used to determine or constrain the scattering amplitudes of particles in quantum field theory using simple principles. Over the past few decades, some physicists have tried to use this technique to study different physics theories and phenomena.

Groundbreaking technique yields important new details on silicon, subatomic particles and possible 'fifth force'

Using a groundbreaking new technique at the National Institute of Standards and Technology (NIST), an international collaboration led by NIST researchers has revealed previously unrecognized properties of technologically crucial silicon crystals and uncovered new information about an important subatomic particle and a long-theorized fifth force of nature.

After 20 years of trying, scientists succeed in doping a 1D chain of cuprates

Self-assembled optical cavities can reach a strong-coupling state that supports polariton formation

A team of researchers at Chalmers University of Technology has found a way to create self-assembling optical cavities that can reach a strong-coupling state that supports polariton formation. In their paper published in the journal Nature, the group describes how their optical cavities were made and possible uses for them. Johannes Feist with the Autonomous University of Madrid has published a News and Views piece on the work done by the team on this effort in the same journal issue.

Unprecedented plasma lensing for high-intensity lasers

High-power laser pulses focused to small spots to reach incredible intensities enable a variety of applications, ranging from scientific research to industry and medicine. At the Berkeley Lab Laser Accelerator (BELLA) Center, for instance, intensity is key to building particle accelerators thousands of times shorter than conventional ones that reach the same energy. However, laser-plasma accelerators (LPAs) require sustained intensity over many centimeters, not just a spot focus that rapidly expands because of diffraction.
