Journal Club: First observation of ‘superballistic’ electrons, flowing like a viscous fluid in graphene

Taking advantage of graphene’s special properties, physicists have experimentally observed a stream of record-breaking electrons that move with a conductance exceeding the limit theorists established decades ago. The researchers reported their findings recently in Nature Physics. For more than half … Continue reading

Journal Club: A new, twisted topological insulator

About a decade ago, physicists began identifying and probing materials that suffer something of an identity crisis. On the surface of these crystals, electrons flow and form currents, like in a conductor. But in the interior, electrons are pinned and … Continue reading

Journal Club: Super-sensitive new microscope uses ultracold atoms to image magnetic fields at high precision

In recent years, physicists have developed an arsenal of sensitive, high-resolution tools to probe the smallest magnetic fields, revealing nanoscale subtleties lost in larger-scale measurements. An understanding of these structures can offer insights into exotic quantum materials. A new microscope … Continue reading

Journal Club: How the principles of principals affect student values

Kids go to school to study math, science, literature, and other subjects. But at least since the time of Plato, philosophers and others have highlighted the importance of educational institutions in shaping the values of students, who will be tomorrow’s … Continue reading

Journal Club: Finding new ways to store higher-density information with ferroelectric materials

Recent findings suggest early proof of principle for a new way to read, write and erase information in much smaller areas than conventional memory. The method entails ferroelectric thin films, which store information using the domains’ polarization directions like the … Continue reading
