Building electronic devices often requires stacking different crystalline materials on top of one another with atomic precision. This process, called heteroepitaxy, works best when the two crystals share similar atomic patterns. When their symmetries differ, the upper crystal tends to grow in several orientations at once instead of a single one, creating defects that degrade […]
Plutonium has captured the attention of scientists since its discovery in the early 1940s. This enigmatic element has an important role to play in emerging energy technologies like nuclear batteries and reactors, but it also has complicated electronic behavior that causes some intriguing effects. Its electron structure contributes to unconventional entropic properties at low temperatures […]
In the search for novel materials, the simulation of quantum matter is an extremely demanding computational task, which is expected to profit substantially from the surge of quantum technologies. Quantum algorithms for programmable quantum computers offer the most flexible approaches, but tailor-made quantum simulators are particularly well suited for large-scale simulations. For instance, tremendous efforts […]
Charge density wave (CDW) is a many-body state of matter in which both lattice and electron density are modulated by a new periodicity. CDW features discrete translational symmetry-breaking, and mostly occurs in low-dimensional materials. Although CDW behaviours have been found in many materials, the underlying mechanism and the driving forces of CDW transition are still […]
