Black holes are regions in space where gravity is very strong—so strong that nothing that enters them can escape, including light. Theoretical predictions suggest that there is a radius surrounding black holes known as the event horizon. Once something passes the...

Researchers gather numerical evidence of quantum chaos in the Sachdev-Ye-Kitaev model
Over the past few years, many physicists worldwide have conducted research investigating chaos in quantum systems composed of strongly interacting particles, also known as many-body chaos. The study of many-body chaos has broadened the current understanding of quantum...
The direct observation of the Pauli principle
The Pauli exclusion principle is a law of quantum mechanics introduced by Austrian physicist Wolfgang Pauli, which offers valuable insight about the structure of matter. More specifically, the Pauli principle states that two or more identical fermions cannot...
Researchers demonstrate the potential of a new quantum material for creating two spintronic technologies
Over the past decade or so, physicists and engineers have been trying to identify new materials that could enable the development of electronic devices that are faster, smaller and more robust. This has become increasingly crucial, as existing technologies are made of...
The first observation of a marginal Fermi glass
For several years, the condensed-matter physics community has been trying to gain a better understanding of material systems made up of strongly interacting particles. Interestingly, many metals can be described as systems with effectively weakly interacting...
Long-distance and secure quantum key distribution (QKD) over a free-space channel
Quantum key distribution (QKD) is a technique that enables secure communications between devices using a cryptographic protocol that is partly based on quantum mechanics. This communication method ultimately allows two parties to encrypt and decrypt messages they send...
A realistic model of the ITER tokamak magnetic fusion device
Tokamaks, devices that use magnetic fields to confine plasma into torus-shaped chamber, could play a crucial role in the development of highly performing nuclear fusion reactors. The ITER tokamak, which is set to be the largest nuclear tokamak in the world, is...
The long-range transport of deconfined magnetic hedgehogs
Spintronics is an emerging area of research that aims to develop devices that transmit, process and store information leveraging the intrinsic angular momentum of electrons, known as spin. A key objective of spintronics studies is to identify strategies to use...
Bound-charge engineering: A new strategy to develop nanowire transistors
In recent years, physicists and electronic engineers have been trying to identify materials that could be used to fabricate new types of electronic devices. One-dimensional (1-D) and two-dimensional (2-D) materials have been found to have particularly advantageous...
The realization of a single-quantum-dot heat valve
While many research teams worldwide are trying to develop highly performing quantum computers, some are working on tools to control the flow of heat inside of them. Just like conventional computers, in fact, quantum computers can heat up significantly as they are...
