Fractons, as a new type of exotic quasiparticle, have attracted immense attention due to their unique properties. Here, we construct a connection between fractons and polarons. We derive microscopic situations in which polarons and their two-body bound states, known as bipolarons, map exactly on to fractons and their two-body counterparts, dipoles.

Frustrated fractons: Fractons, a new type of quasiparticles, have attracted attention due to their unusual mobility constraints. But, where can we find fractons in the lab? We show that frustration of the background due to hole motion in hole-doped antiferromagnets produces fractonic quasiparticles.

Machine learning is a powerful tool to analyze complex data, but can it help reveal unexplored domains of knowledge? We answer this question in the affirmative, showing in this work that one can predict phase transitions using Gaussian process extrapolation across parameter space.

Bipolarons shed off extra weight: Normally two polarons form a bipolaron by increasing their net potential energy. As a result, the two polarons tend to remain spatially close to each other, and the bipolaron becomes heavy. Here, we show that polarons can bind by increasing their kinetic energy, leading to light bipolarons and a possible new mechanism for high-temperature superconductivity.

Quantum mechanics freezes a hot plasma: We show that Rydberg molecules in a quenched molecular plasma interfere to form a stable long-lived localized state. Randomness in the Rydberg plasma acts decisively to freeze the dynamics of Rydberg excitations in a process suggestive of many-body localization, explaining recent experimental observations.
