Mysterious event may be caused by a tau neutrino

Theoretical physicists calculate the origin of a high-energy particle track captured by the IceCube Neutrino Observatory.

When photons spice up the energy levels of quantum particles

For the first time, a team of mathematical physicists, call upon supersymmetry to explain the behavior of particles that have received a photon and are subjected to particular potential energies known as shape-invariant potentials.

Rush hour metro crowd governed by people's eagerness to go home

Ever found yourself crushed in a metro station at rush hour? The mathematician Carlo Bianca and physicist Caterina Mogno, both from the engineering research lab ECAM-EPMI in Cergy-Pontoise, France, have developed a new model to study the movement of crowds exiting a metro station.

Controlling magnetic spin with electric fields

EPFL physicists have found a way to reverse electron spins using electric fields for the first time, paving the way for programmable spintronics technologies.

Mysterious IceCube event may be caused by a tau neutrino

Eight years ago, the IceCube detector, a research center located at the South Pole to detect neutrinos emanating from the cosmos, was commissioned. Three years later, it began to register the first momentous results. The detection of high-energy neutrinos by IceCube made viable completely new options for explaining how our universe works.

Nano-scale 'vibrational wave' research could transform the field of materials physics

New UK research studying the vibrational properties of matter, or phonons, at the nanoscale, could bring transformational advances in the design and development of a new generation of advanced materials, such as thermoelectrics, among many others.

Observation of anisotropic magneto-Peltier effect

NIMS and Tohoku University have jointly observed an anisotropic magneto-Peltier effect—a thermoelectric conversion phenomenon in which simple redirection of a charge current in a magnetic material induces heating and cooling. Thermoelectric heating and cooling are conventionally achieved by applying a charge current to a junction between two different electrical conductors. In this study, the researchers demonstrated a novel thermal control function using a single magnetic material without relying on a junction structure.

New study explores cell mechanics at work

It's a remarkable choreography. In each of our bodies, more than 37 trillion cells tightly coordinate with other cells to organize into the numerous tissues and organs that make us tick.

Carbon nanotube optics provide optical-based quantum cryptography and quantum computing

Researchers are exploring the enhanced potential of carbon nanotubes as single-photon emitters for quantum information processing.
