New way to measure the stability of next-generation magnetic fusion devices

Scientists have discovered an alternative method for measuring the stability of fusion plasma, a critical task for researchers seeking to bring the fusion that powers the sun to Earth.

Puzzling on a quantum chessboard

Physicists are proposing a new model that could demonstrate the supremacy of quantum computers over classical supercomputers in solving optimization problems. They demonstrate that just a few quantum particles would be sufficient to solve the mathematically difficult N-queens problem in chess even for large chess boards.

Could vacuum physics be revealed by laser-driven microbubble?

Scientists have discovered a novel mechanism which they refer to as microbubble implosion (MBI) in 2018. In this study, the group confirmed that during MBI, an ultrahigh electrostatic field close to the Schwinger field could be achieved because micron-sized bubbles embedded in a solid hydride target implode to have nanometer-sized diameters upon ionization.

Quantum sensor breakthrough using naturally occurring vibrations in artificial atoms

A team of scientists have discovered a new method that could be used to build quantum sensors with ultra-high precision.

Terahertz technology escapes the cold

Scientists have achieved the first realization of a terahertz quantum cascade laser operating without cryogenic cooling. This feat heralds the widespread use of these devices in practical applications.

How to 'lock' heat in place using quantum mechanics

In a global first, scientists have demonstrated that heat energy can be manipulated by utilizing the quantum mechanical principle of anti-parity-time symmetry. Using this method, they were able to control the flow of heat in a material.

Measuring light and vacuum fluctuations from a time flow perspective

Some of the greatest unanswered questions about the nature of the universe are related to light, the vacuum (i.e. space where neither matter nor radiation exists), and their relationship with time. In the past, physicists and philosophers have addressed a variety of complex questions, for instance, what is the nature of the vacuum, and how is the propagation of light connected to the passing of time?

Equations from fluid dynamics used to find optimum arrangement of rods in dandelion pappus

A team of researchers from École Polytechnique Fédérale de Lausanne, the University of Twente and Università di Pisa has used equations from fluid dynamics to find the optimum arrangement of rods in a dandelion pappus. In their paper published in the journal Physical Review Letters, the group describes their work and what it showed.

Scientists discover how to 'lock' heat in place using quantum mechanics

A ground-breaking study conducted by researchers from the National University of Singapore (NUS) has revealed a method of using quantum mechanical wave theories to "lock" heat into a fixed position.

Tour de France pelotons governed by sight, not aerodynamics

The 2019 Tour de France has just begun. As 190 riders speed through the streets of France, spectators will marvel at the tightly-packed formation of cyclists known as the peloton. Fans will argue that a peloton creates an aerodynamic advantage, allowing riders to conserve energy throughout the grueling three-week race.
