Charring Auh#Coldatoms are atoms cooled to microkelvin or nanokelvin temperatures—near absolute zero—using specialized laser and magnetic techniques. At these ultra-cold temperatures, atomic motion slows drastically, allowing researchers to manipulate them for quantum computing, high-precision sensors, and studies of fundamental physics like Bose-Einstein condensates.— with Griffin Museum of Science and Industry at Griffin Museum of Science and Industry.
QUINTO projectI am still alive, and there are big news for the project – news that are over one month overdue, but I was so focused on writing grant proposals that I couldn’t find time to write about it. Long story short: we finished the preprint of our spin liquid paper (https://arxiv.org/pdf/2512.05630). This work originated much before I came to Darrick Chang’s group, thus I am only a third author, but I did my part within the QUINTO project.
What is it about? Basically, atoms can make photons interacting with each other. In general, the interaction of many simple objects can lead to unusual, counterintuitive behavior. For example, many interacting electrons can form fractional quantum Hall states, and many interacting spins can form spin liquids – both being complicated quantum states, whose unusual properties manifest themselves with emergence of “quasiparticles” – objects that behave like individual particles, although in reality they are collective states of many particles. These quasiparticles can behave unlike any elementary particle found in nature – for example, they can have a fraction of single electron charge, and be neither bosons nor fermions but “anyons”. In the paper, we ask: can we observe similar effects with atoms and light?
