Semiconductor Physics

Focus: Vibrations and Electrons Team Up in New Quantum Entity

Theorists propose an experiment to observe a “phoniton,” a novel hybrid of an electron and a quantum of vibration in a crystal lattice. Read More »


Focus: A New Way to Channel Light

Light passing through a pair of adjacent glass strips generates a slight bending in the material, causing the light to concentrate into narrow tracks. The technique works for all wavelengths of light. Read More »

Quantum Physics

Focus: Landmarks—Lamb Shift Verifies New Quantum Concept

The 1947 discovery of a small discrepancy in hydrogen’s atomic spectrum came at just the right time to push quantum theory forward. Read More »


Focus: Landmarks—Atomic Force Microscope Makes Angstrom-Scale Images

The atomic force microscope, introduced in 1986, provided atomic-scale pictures of surfaces, with few limitations on the type of sample. Read More »

Nuclear Physics

A model mixing Brownian motion with purposeful movement guided by vocal signals suggests that Mongolian gazelle herds may have developed an efficient foraging strategy. Read More »


Focus: Gravity Makes the Universe Classical

Weak gravitational waves that fill the Universe are enough to disturb quantum superpositions and ensure that large objects behave according to classical physics. Read More »


Focus: Landmarks—The Birth of Photonic Crystals

Periodic structures that control photons, much as semiconductors control electrons, came into being in the late 1980s, through a complex interchange between experiment and theory. Read More »
