Many-body localization (MBL), characterized by the absence of thermalization and the violation of conventional thermodynamics, has elicited much interest both as a fundamental physical phenomenon and for practical applications in quantum information. A phenomenological model, which describes the system using a complete set of local integrals of motion (LIOMs), provides a powerful tool to understand MBL, but can be usually only computed approximately. Here we explicitly compute a complete set of…

Structural properties of local integrals of motion across the many-body localization transition via a fast and efficient method for their construction
Many-body localization (MBL) is a novel prototype of ergodicity breaking due to the emergence of local integrals of motion (LIOMs) in a disordered interacting quantum system. To better understand the
Nonthermalized dynamics of flat-band many-body localization
We find that a flat-band fermion system with interactions and without disorders exhibits nonthermalized ergodicity-breaking dynamics, an analog of many-body localization (MBL). In the previous works
Numerical Evidence for Many-Body Localization in Two and Three Dimensions.
An algorithm is developed that can find approximate binary ℓ bits in arbitrary dimensions by adaptively generating a basis of operators in which to represent the ™ bit and validates the evidence of MBL phenomenology in the other two- and three-dimensional models studied.
Extracting many-body localization lengths with an imaginary vector potential
One challenge of studying the many-body localization transition is defining the length scale that diverges upon the transition to the ergodic phase. In this manuscript we explore the localization
Loschmidt echo singularities as dynamical signatures of strongly localized phases
Quantum localization (single-body or many-body) comes with the emergence of local conserved quantities—whose conservation is precisely at the heart of the absence of transport through the system. In


Exploring the many-body localization transition in two dimensions
The observation of a many-body localization transition between thermal and localized phases for bosons in a two-dimensional disordered optical lattice is reported, highlighting the power of quantum simulation to solve problems that are currently inaccessible to classical computing techniques.
Many-body localization in a quantum simulator with programmable random disorder
Interacting quantum systems are expected to thermalize, but in some situations in the presence of disorder they can exist in localized states instead. This many-body localization is studied
Observation of many-body localization of interacting fermions in a quasirandom optical lattice
This experiment experimentally observed this nonergodic evolution for interacting fermions in a one-dimensional quasirandom optical lattice and identified the MBL transition through the relaxation dynamics of an initially prepared charge density wave.
Many‐body localization from the perspective of Integrals of Motion
We study many‐body localization (MBL) from the perspective of integrals of motion (IOMs). MBL can be understood phenomenologically through the existence of macroscopically many localized IOMs. We
Spectroscopic signatures of localization with interacting photons in superconducting qubits
This work introduces a many-body spectroscopy technique based on a chain of superconducting qubits to study quantum phases of matter and introduces disorder to study the statistics of the energy levels of the system as it undergoes the transition from a thermalized to a localized phase.
Out‐of‐time‐order correlations in many‐body localized and thermal phases
We use the out‐of‐time‐order (OTO) correlators to study the slow dynamics in the many‐body localized (MBL) phase. We investigate OTO correlators in the effective (“l‐bit”) model of the MBL phase, and
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
