Meetings: Highlights from DAMOP 2016

Quantum simulations enter the realm of high-energy physics, while a professor reboots graduate-level classical mechanics. Read More »

Topological Insulators

Synopsis: A Good Match for Germanene

Germanene—the germanium analog of graphene—can remain a topological insulator when placed on a molybdenum disulfide substrate. Read More »

Quantum Physics

Viewpoint: Classical Simulation of Quantum Systems?

Richard Feynman suggested that it takes a quantum computer to simulate large quantum systems, but a new study shows that a classical computer can work when the system has loss and noise. Read More »

Astrophysics

Synopsis: Solar Cycle Affects Cosmic Ray Positrons

Discrepancies in the positron content of cosmic rays measured at different times are explained by the periodic reversal of the solar magnetic field’s direction. Read More »

Focus: LIGO Bags Another Black Hole Merger

LIGO has detected a second burst of gravitational waves from merging black holes, suggesting that such detections will soon become routine and part of a new kind of astronomy. Read More »

Nuclear Physics

Synopsis: Trailing the Photons from Neutron Decay

A high-precision measurement of the photons emitted by neutron decays brings researchers closer to a new test of the standard model. Read More »

Quantum Physics

Viewpoint: Measuring Quantum Kicks from a Beam of Light

Force sensors levitated by light have reached the quantum regime, in which their sensitivity is limited by the momentum kicks of individual photons. Read More »

Quantum Information

Focus: Landmarks—Correcting Quantum Computer Errors

In the mid-1990s, researchers proposed methods to preserve the integrity of quantum bits—techniques that may become the key to practical quantum computing on a large scale. Read More »
