Symmetry-enforced three-dimension Dirac phononic crystals

Dirac semimetals are critical states of topologically distinct phases. Such gapless topological states have been accomplished by a band-inversion mechanism, in which the Dirac points can be annihilated pairwise by perturbations ...

Decarbonizing your ride for a more stable climate

Transportation produces a sizable amount of greenhouse gas emissions, largely by using petroleum to power internal combustion engines. Alternatives –- for example, organic materials such as grasses to produce fuels or electricity ...

Scientists have developed a new concept of mathematical modeling

A team of scientists from the Research Center "Fundamental Problems of Thermophysics and Mechanics," of Samara Polytech is engaged in the construction of new mathematical models and the search for methods for their study ...

Gaining insight into the energy balance of earthquakes

Researchers at EPFL's Computational Solid Mechanics Laboratory and the Weizmann Institute of Science have modeled the onset of slip between two bodies in frictional contact. Their work, a major step forward in the study of ...

Science follows from furry mysteries

Greg Gbur's new book from Yale University Press, "Falling Felines and Fundamental Physics," takes on a strange topic for a physicist—the mysteries of the cat.

Quantum simulation more stable than expected

A localization phenomenon boosts the accuracy of solving quantum many-body problems with quantum computers. These problems are otherwise challenging for conventional computers. This brings such digital quantum simulation ...

Polymer movement: key to next-generation coatings

Researchers in the Department of Materials Science and Engineering at Texas A&M University, led by doctoral student Victor Selin and Dr. Svetlana Sukhishvili, are making headway in understanding fundamental principles that ...

Scientist describes fundamental process when ice is compressed

Almost three-quarters of the earth's surface is covered by water. Almost two-thirds of the human body is made up of it. We drink it. We use it in our homes and in industry. As a solid, it's ice. As a gas, it's steam.
