Generating Mono-Cycle Terahertz Pulses from Shift Currents in Asymmetric Quantum Wells

A time-dependent electric current emits an electromagnetic wave, a basic physical effect exploited in telecom antennas. Transferring this mechanism to the ultrashort length and time scales of the quantum world allows for generating intense picosecond terahertz (THz) pulses in asymmetric semiconductor quantum structures.

Brown Researchers Uncover a Surprising New Phenomenon in Magic-Angle Graphene

When two sheets of the carbon nanomaterial graphene are stacked together at a particular angle with respect to each other, it gives rise to some fascinating physics. For instance, when this so-called "magic-angle graphene" is cooled to near absolute zero, it suddenly becomes a superconductor, meaning it conducts electricity with zero resistance.

Researchers Achieve Super-Resolution Imaging of Single Ion in an Ion Trap System

The team of academician GUO Guangcan of University of Science and Technology of China (USTC) of the Chinese Academy of Sciences has made important progress in the research of cold atom super-resolution imaging. The team achieved super-resolution imaging of a single ion in an ion trap system. The results were published in Physical Review Letters.

Scientists Show How Matter and Antimatter Seem to Respond to Gravity in the Same Way

An experiment to measure — to an exceptionally precise degree — the charge-to-mass ratios of protons and antiprotons, enabled the RIKEN-led BASE partnership at CERN, Geneva, Switzerland, to discover that, within the ambiguity of the experiment, matter and antimatter react to gravity in the same manner.

Physicists Observe the Interplay of Interactions and Quantum Mechanics in Ultracold Atoms

The world we experience is governed by classical physics. How we move, where we are, and how fast we're going are all determined by the classical assumption that we can only exist in one place at any one moment in time.

New Study Finds that Black Holes are Giant Fuzzballs

According to a recent study, black holes are giant fuzzballs. The study tries to end the debate over Stephen Hawking’s well-known information paradox. This was the issue created by Hawking’s conclusion that any data that enters a black hole cannot leave.

Quantum-Probe Field Microscopy for Imaging Ultrafast Electric Waveforms

Microscopic electric fields govern a remarkable variety of phenomena in condensed matter and their ultrafast evolutions drive plasmonics, phononics and highspeed nanoelectronics. Access to high-frequency electric waveforms is of crucial importance to diverse disciplines in nanoscience and technology, yet, microscopic measurements are still severely limited.
