Microcombs – chip-scale devices that generate and measure frequencies of light with exquisite accuracy – have transformed timekeeping and boosted optical
Researchers have created a prototype quantum computer with a record number of qubits—the analog of bits in an ordinary computer—capable of performing logical
In research, sometimes the bumpy path proves to be the best one. By creating tiny, periodic bumps in a miniature racetrack for light, researchers at the
SPM is a general acronym for various probe instruments. The "P" in SPM stands for various types of probe measurements, such as capacitance (C), force (F), tunneling (T), etc. The scanning tunneling microscope (STM), including custom designs at the CNST, uses the quantum mechanical principle of
Developing and exploiting nanodevices for quantum and nanotechnologies requires nanoscale and atomic scale modeling of ultrasmall structures, devices, their operation, and their response to probes. Key challenges of understanding physics at the quantum/classical interface and measurement at the
We investigate the interaction of light with semiconductor-based nanostructures. We extend concepts of entanglement and coherence in atomic physics to our solid-state systems. Our devices are based on semiconductors, like GaAs. We use InAs quantum dots (QDs) in GaAs as artificial atoms; they have
The energy spectrum of graphene's charge carriers is very different from ordinary metals and semiconductors. The conduction and valance bands meet at conical points, where the carriers have an energy that is linear in momentum, giving rise to a zero effective mass [Fig.1(a)]. This dispersion is
