Generating cold with solids
After more than a century, physicists aim to dethrone the tried-and-tested technology of the refrigerator, as cooling can be made more energy-efficient.

A new study published in Nature Communications delves into the manipulation of atomic-scale spin transitions using an external voltage, shedding light on the practical implementation of spin control at the nanoscale for quantum ...
Researchers at the Max-Born-Institute have now mapped the linear and nonlinear optical polaron response using ultrafast two-dimensional spectroscopy in the THz frequency range. As they discuss in the current issue of Physical ...

Ordinary pencil lead holds extraordinary properties when shaved down to layers as thin as an atom. A single, atom-thin sheet of graphite, known as graphene, is just a tiny fraction of the width of a human hair. Under a microscope, ...
