Thermoelectrics: From heat to electricity

A lot of heat gets lost during the conversion of energy. Estimates even put it at more than 70%. However, in thermoelectric materials, such as those being studied at the Institute of Solid State Physics at TU Wien, heat can ...

New kirigami-inspired models predict how new metamaterials behave

A traditional paper crane is a feat of artistry. Every fold in origami leads to the transformation of a single square sheet of paper into a bird, a dragon, or a flower. Origami discourages gluing, marking or cutting the paper, ...

Novel gel proves itself to be a highly tunable color filter

Color these scientists happy. An exotic gel they studied at the National Institute of Standards and Technology (NIST) has an unexpected property: The material's temperature determines which color of light can pass through ...

Taking quantum control of life's building blocks

Life (as we know it) is based on carbon. Despite its ubiquity, this important element still holds plenty of secrets, on earth and in the heavens above us. For example, astrophysicists like Columbia's Daniel Wolf Savin who ...

Researchers extend quantum amplification to Floquet systems

Detection of weak signals is a crucial step in the verification of physics hypotheses and making breakthroughs in cutting-edge and fundamental physics research. However, if the signals are too weak to measure, they need enhancement. ...

New ultrathin capacitor could enable energy-efficient microchips

The silicon-based computer chips that power our modern devices require vast amounts of energy to operate. Despite ever-improving computing efficiency, information technology is projected to consume around 25% of all primary ...

Physicists build an atom laser that can stay on forever

Lasers produce coherent waves of light: All the light inside a laser vibrates completely in sync. Meanwhile, quantum mechanics tells us that particles like atoms should also be thought of as waves. As a result, we can build ...

Alignment of quantized levels in valleytronic materials

National University of Singapore researchers have predicted that Landau levels belonging to different valleys in a two-dimensional (2D) valleytronic material, monolayer tungsten diselenide (WSe2), can be aligned at a critical ...

New, highly tunable composite materials—with a twist

Watch for the patterns created as the circles move across each other. Those patterns, created by two sets of lines offset from each other, are called moiré (pronounced mwar-AY) effects. As optical illusions, moiré patterns ...

Researchers observe continuous time crystal

Researchers from the Institute of Laser Physics at Universität Hamburg have succeeded for the first time in realizing a time crystal that spontaneously breaks continuous time translation symmetry. They report their observation ...
