We investigate relaxation in the recently discovered ``fracton'' models and discover that these models naturally host glassy quantum dynamics in the absence of quenched disorder. We begin with a discussion of ``type I'' fracton models, in the taxonomy of Vijay, Haah, and Fu. We demonstrate that in these systems, the mobility of charges is suppressed exponentially in the inverse temperature. We further demonstrate that when a zero-temperature type I fracton model is placed in contact with a… 
Fractons from confinement in one dimension
Recent work has shown that two seemingly different physical mechanisms, namely fracton behavior and confinement, can give rise to non-ergodicity in one-dimensional quantum many-body systems. In this
Localization in Fractonic Random Circuits
We study the spreading of initially-local operators under unitary time evolution in a 1d random quantum circuit model which is constrained to conserve a $U(1)$ charge and its dipole moment, motivated
Dynamical Scar States in Driven Fracton Systems.
TLDR
Dynamical scar states arise directly from fracton conservation laws, providing a concrete mechanism for the appearance of scars in systems with constrained quantum dynamics.
Emergent Glassy Dynamics in a Quantum Dimer Model.
TLDR
Based on the model's kinematic constraints, a mechanism of relaxation that rests on emergent, highly detuned multidefect processes in a staggered background gives rise to slow, glassy dynamics at low temperatures even in the thermodynamic limit.

As new kinds of stabilizer code models, fracton models have been promising in realizing quantum memory or quantum hard drives. However, it has been shown that the fracton topological order of 3D
Hilbert space fragmentation produces a"fracton Casimir effect"
Fracton systems exhibit restricted mobility of their excitations due to the presence of higherorder conservation laws. Here we study the time evolution of a one-dimensional fracton system with charge
Gauging fractons: Immobile non-Abelian quasiparticles, fractals, and position-dependent degeneracies
The study of gapped quantum many-body systems in three spatial dimensions has uncovered the existence of quantum states hosting quasiparticles that are confined, not by energetics but by the
Twisted fracton models in three dimensions
We study novel three-dimensional quantum phases of matter which support particles with restricted mobility, including immobile "fracton" excitations. Many fracton models may be viewed as generalized
Absence of finite temperature phase transitions in the X-Cube model and its Zp generalization
We investigate thermal properties of the X-Cube model and its $\mathbb{Z}_{p}$ `clock-type' ($p$X-Cube) extension. In the latter, the elementary spin-1/2 operators of the X-Cube model are replaced by
Fractons
Fracton phases constitute a new class of quantum state of matter. They are characterized by excitations that exhibit restricted mobility, being either immobile under local Hamiltonian dynamics or
