The bond-algebraic approach to dualities
An algebraic theory of dualities is developed based on the notion of bond algebras. It deals
with classical and quantum dualities in a unified fashion explaining the precise connection …

Light-cone-like spreading of correlations in a quantum many-body system
In relativistic quantum field theory, information propagation is bounded by the speed of light.
No such limit exists in the non-relativistic case, although in real physical systems, short …

Statistical localization: From strong fragmentation to strong edge modes
Certain disorder-free Hamiltonians can be nonergodic due to a strong fragmentation of the
Hilbert space into disconnected sectors. Here, we characterize such systems by introducing …

Mpemba effects in nonequilibrium open quantum systems
The Mpemba effect was originally referred to as the faster icing of a higher-temperature
system than a lower-temperature system, and was later generalized to anomalous decays of …
