Thermal inclusions: how one spin can destroy a many-body localized phase
Pedro Ponte, C. R. Laumann, David A. Huse +1
Many-body localized (MBL) systems lie outside the framework of statistical mechanics, as they fail to equilibrate under their own quantum dynamics. Even basic features of MBL syste…
Clustering in Hilbert space of a quantum optimization problem
S. C. Morampudi, B. Hsu, S. L. Sondhi +2
The solution space of many classical optimization problems breaks up into clusters which are extensively distant from one another in the Hamming metric. Here, we show that an analo…
Localization and symmetry breaking in the quantum quasiperiodic Ising glass
Anushya Chandran, C. R. Laumann
Quasiperiodic modulation can prevent isolated quantum systems from equilibrating by localizing their degrees of freedom. In this article, we show that such systems can exhibit dyna…
Long coherence times for edge spins
Jack Kemp, Norman Y. Yao, Christopher R. Laumann +1
We show that in certain one-dimensional spin chains with open boundary conditions, the edge spins retain memory of their initial state for very long times. The long coherence times…
