Finding Critical States of Enhanced Memory Capacity in Attractive Cold Bosons

Understand

We discuss a class of quantum theories which exhibit a sharply increased memory storage capacity due to emergent gapless degrees of freedom.

• Their realization, both theoretical and experimental, is of great interest.
• On the one hand, such systems are motivated from a quantum information point of view.
• On the other hand, they can provide a framework for simulating systems with enhanced capacity of pattern storage, such as black holes and neural networks.
