How AI and ML Will Affect Physics
The more physicists use artificial intelligence and machine learning, the more important it becomes for them to understand why the technology works and when it fails. Read More »
Making a Beamline for Deep UV Spectroscopy
By using a pair of offset beams, researchers are able to generate femtosecond UV pulses that can be aimed directly into a target as a spectroscopic probe. Read More »
Quantum Ratchet Made Using an Optical Lattice
Researchers have turned an optical lattice into a ratchet that moves atoms from one site to the next. Read More »
Antimatter Feels Gravity Just like Matter
The first direct observations of antihydrogen atoms falling in Earth’s gravity show that they experience gravity in the same way as ordinary matter does. Read More »
In a Twist, Composite Fermions Form and Flow without a Magnetic Field
Certain twisted semiconductor bilayers are predicted to host a Fermi liquid of composite fermions—remarkably, without an applied magnetic field. Read More »
A Fine Probe of Layer Stacking
The combination of nuclear magnetic resonance with first-principles calculations uncovers the stacking patterns of layers of a quantum material—information that could enable a deeper understanding of the material’s behavior. Read More »
Quasiparticles Repel, Then Attract
Resonant excitation of a thin-film semiconductor leads to impurities that attract rather than repel each other, providing a possible tool for manipulating superconductivity. Read More »
Breakthrough Prize for Quantum Field Theorists
The 2024 Breakthrough Prize in Fundamental Physics goes to John Cardy and Alexander Zamolodchikov for their work in applying field theory to diverse problems. Read More »
Two Black Holes Masquerading as One
Black holes may be less unique than previously thought, as the expansion due to a cosmological constant can hold apart a pair of holes and allow them to mimic a single black hole. Read More »
