Roton Quasiparticles Observed In Quantum Gas
Discovered in liquid helium about 80 years ago, superfluidity is a counterintuitive phenomenon, in which quantum physics and particle-wave duality manifest at the macroscopic level. Since then, it has yielded many advances in understanding quantum matter, yet leaving mysterious some … Continue reading

Silicon Pixel Detectors Enable Helium-beam Radiography
Hadron therapy shows potential to improve the effectiveness of cancer radiotherapy. By exploiting the characteristic depth-dose distributions of hadrons in tissues (the Bragg peak), the technique offers precise delivery of radiation dose. The large gradients of the highly conformal dose … Continue reading
