Motivated by the outstanding challenge of realizing low-temperature states of quantum matter in synthetic materials, we propose and study an experimentally feasible protocol for preparing topological states such as Chern insulators. By definition, such (nonsymmetry protected) topological phases cannot be attained without going through a phase transition in a closed system, largely preventing their preparation in coherent dynamics. To overcome this fundamental caveat, we propose to couple the…

Bilayer Haldane system: Topological characterization and adiabatic passages connecting Chern phases

We present a complete topological characterization of a bilayer composite of two Chern insulators (specifically, Haldane models) and explicitly establish the bulk-boundary correspondences. We show

Driven quantum many-body systems and out-of-equilibrium topology

This review presents some of the work done in India in the area of driven and out-of-equilibrium systems with topological phases, and discusses the effects of periodic driving in some of them.

Engineered dissipation for quantum information science

Quantum information processing relies on the precise control of non-classical states in the presence of many uncontrolled environmental degrees of freedom. The interactions between the relevant

Linking invariant for the quench dynamics of a two-dimensional two-band Chern insulator

We discuss the topological invariant in the ($2+1$)-dimensional quench dynamics of a two-dimensional two-band Chern insulator starting from a topological initial state (i.e., with a nonzero Chern

A dark state of Chern bands: Designing flat bands with higher Chern number

We introduce a scheme by which flat bands with higher Chern number \vert C\vert>1|C|>1 can be designed in ultracold gases through a coherent manipulation of Bloch bands. Inspired by quantum-optics



Observation of symmetry-protected topological band with ultracold fermions

This work reports the observation for ultracold atoms of a noninteracting SPT band in a one-dimensional optical lattice and studies quench dynamics between topologically distinct regimes, revealing two fundamental types of spin-relaxation dynamics related to bulk topology.

Dynamical preparation of Floquet Chern insulators

An exact study of the time evolution of a graphene-like system subjected to a circularly polarized electric field is presented and it is proved that for infinite (translationally invariant) systems the Chern number is conserved under unitary evolution.

Uncover Topology by Quantum Quench Dynamics.

This work presents a new dynamical approach for ultracold-atom systems to uncover their band topology, and provides solid evidence to demonstrate its experimental advantages.

Quantum annealing and nonequilibrium dynamics of Floquet Chern insulators

Inducing topological transitions by a time-periodic perturbation offers a route to controlling the properties of materials. Here we show that the adiabatic preparation of a non-trivial state involves

Dynamical Buildup of a Quantized Hall Response from Nontopological States.

A two-dimensional system initialized in a topologically trivial state before its Hamiltonian is ramped through a phase transition into a Chern insulator regime is considered, and a geometric picture of this phenomenology in terms of the time-dependent Berry curvature is provided.

Experimental realization of the topological Haldane model with ultracold fermions

The experimental realization of the Haldane model and the characterization of its topological band structure are reported, using ultracold fermionic atoms in a periodically modulated optical honeycomb lattice and a direct extension to realize spin-dependent topological Hamiltonians is proposed.

Classification of topological quantum matter with symmetries

Topological materials have become the focus of intense research in recent years, since they exhibit fundamentally new physical phenomena with potential applications for novel devices and quantum

Single-spin addressing in an atomic Mott insulator

This work was able to flip the spin of individual atoms in a Mott insulator with sub-diffraction-limited resolution, well below the lattice spacing, and created arbitrary spin patterns by sequentially addressing selected lattice sites after freezing out the atom distribution.

Measuring topology from dynamics by obtaining the Chern number from a linking number

This work defines and measures a linking number between static and dynamical vortices, which directly corresponds to the ground-state Chern number, and measures the instantaneous Chern number and shows that it remains zero under the unitary dynamics.

Observing Topological Charges and Dynamical Bulk-Surface Correspondence with Ultracold Atoms.

It is observed that the total charges in the region enclosed by BISs define a dynamical topological invariant, which equals the Chern number of the postquench band and also characterizes the topological pattern of a dynamicals field emerging on the BISS, rendering the dynamical bulk-surface correspondence.
