A Fully Equivariant Framework for Learning Properties of N atoms and Molecular Hamiltonians

In the fields of chemistry and materials, most successful, widely used machine learning schemes introduced over the last decade aim to model molecular energies or interatomic potentials.

Study Opens New Avenue for Exploring Gauge Field-Induced Topological Physics

Gauge fields describe the basic interactions between charged particles and are responsible for various emergent topological phases of matter. This concept recently has been further generalized to charge neutral systems by engineering an analog Hamiltonian that governs the effective dynamics of neutral particles subject to magnetic fields.

Physicists Detect a Hybrid Particle Held Together by Uniquely Intense “Glue”

In the particle world, sometimes two is better than one. Take, for instance, electron pairs. When two electrons are bound together, they can glide through a material without friction, giving the material special superconducting properties.

A Comprehensive Overview of Integrated Quantum Photonics

An international team of leading scientists, headed up by Paderborn physicist Professor Klaus Jöns, has compiled a comprehensive overview of the potential, global outlook, background and frontiers of integrated photonics.

Astronomers Capture the Striking End to a Red Supergiant’s Life

For the first time in history, astronomers have imaged in real-time the striking end to a red supergiant’s life — looking at the massive star’s quick self-destruction and eventual death throes before falling into a type II supernova.

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.

Study Finds a New Way to Manipulate Auger Recombination Process in Quantum Dots

Quantum Dot (QD) is a nanometer-sized semiconductor nanocrystal that has unique optical properties such as the ability to emit light in the range of optical frequencies depending on its size.

Optomechanical Quantum Teleportation is an Important Step Toward Hybrid Quantum Internet

Researchers at the Delft University of Technology (TU Delft) in the Netherlands and the University of Campinas (UNICAMP) in Brazil have shown that information encoded in a quantum bit (qubit) consisting of a single photon can be teleported to the mechanical motion of an optomechanical device comprising billions of atoms.

Physicists Watch as Ultracold Atoms Form a Crystal of Quantum Tornadoes

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.
