Eighty-six years since electron crystals were first proposed, physicists have now constructed them, trapping electrons in a repeating pattern. The achievement is reported in the journal Nature.
A crystal is made of a repeating pattern of particles but electrons are difficult to keep in place. So an electron crystal is like trying to organize a large number of electrons that won’t stay still — it’s the herding cats of particle physics.
However, this team had an ingenious solution. They built a Wigner crystal using layers of semi-conductors just one atom thick. They then used two different tungsten materials and created a hexagonal pattern known as a moiré superlattice by placing one material on top of the other.
Japan’s Prime Minister Yoshihide Suga has declared a state of emergency for the nation’s capital and surrounding areas as Covid-19 cases surge to the highest levels since the start of the pandemic.
The emergency declaration will be in place from Friday until February 7 and applies to Tokyo and the three neighboring prefectures of Chiba, Saitama and Kanagawa. The emergency includes a number of restrictions on daily life.
Suga has ordered companies to encourage their staff to work from home and reduce office populations by 70%.

The robot is still “in development.”
Samsung’s Bot Handy has a robotic arm that can pick up laundry, load the dishwasher, set the table, pour wine, and bring you a drink. The robot is still in development.
Capturing energy from the Sun with solar panels is only half the story – that energy needs to be stored somewhere for later use. In the case of flow batteries, storage is relegated to vats of liquid. Now, an international team led by University of Wisconsin-Madison scientists has created a new version of these solar flow batteries that’s efficient and long-lasting.
To make the new device, the team combined several existing technologies. It’s a silicon/perovskite tandem solar cell, paired with a redox flow battery, which the team says will allow people to harvest and store renewable energy in one device. Not only is it efficient, but it should be inexpensive and simple enough to scale up for home use.
The energy-harvesting part of the equation combines the long-time industry-leading material – silicon – with a promising young upstart called perovskite. These tandem solar cells have proved better than either material alone, since the two materials capture different wavelengths of light.
