On Many-Body Localization for Quantum Spin Chains
For a one-dimensional spin chain with random local interactions, we prove that many-body localization follows from a physically reasonable assumption that limits the amount of level attraction in the system. The construction uses a sequence of local unitary transformations to diagonalize the Hamiltonian and connect the exact many-body eigenfunctions to the original basis vectors.
متن کاملSpin-orbit density wave induced hidden topological order in URu2Si2
The conventional order parameters in quantum matters are often characterized by 'spontaneous' broken symmetries. However, sometimes the broken symmetries may blend with the invariant symmetries to lead to mysterious emergent phases. The heavy fermion metal URu2Si2 is one such example, where the order parameter responsible for a second-order phase transition at Th=17.5 K has remained a long-stan...

متن کاملMany-body Localization of Cold
In the seminal 1958 paper, Anderson cites the problem of spin diffusion as a motivation to study the quantum effect of localization [1]. The conclusion about the stability of a localized phase was actually reached there for a single quasiparticle hopping between sites with random, broadly distributed energies. The single-particle localization theory, applicable to various systems comprised of n...
متن کاملArea laws in a many-body localized state and its implications for topological order
The question whether Anderson insulators can persist to finite-strength interactions – a scenario dubbed manybody localization – has recently received a great deal of interest. The origin of such a many-body localized phase has been described as localization in Fock space, a picture we examine numerically. We then formulate a precise sense in which a single energy eigenstate of a Hamiltonian ca...
