چکیده

How to characterize topological quantum phases is a fundamental issue in the broad field of matter. From dimension reduction approach, we propose concept high-order band inversion surfaces (BISs) which enable optimal schemes equilibrium by far-from-equilibrium dynamics, and further report experimental simulation. We show that characterization d-dimensional (dD) phase can be reduced lower-dimensional invariants BISs, nth-order BIS (d-n)D interface momentum space. In quenching system from trivial regime, unveil dynamical bulk-surface correspondence dynamics exhibits nontrivial pattern arbitrary universally corresponds so characterizes post-quench Hamiltonian. This provides new with advantages simulate detect states, through highest-order BISs are zero dimension, detection relies on only minimal measurements. experimentally build up simulator spin qubits investigate 3D chiral insulator emulating each one measure correspondence, via being demonstrated.

Exploring topological phases with quantum walks

The quantum walk was originally proposed as a quantum-mechanical analog of the classical random walk, and has since become a powerful tool in quantum information science. In this paper, we show that discrete-time quantum walks provide a versatile platform for studying topological phases, which are currently the subject of intense theoretical and experimental investigations. In particular, we de...

Topological Phases in Narrow-band syst(

I discuss several novel topological phases in correlated electron systems, realized through spin-orbit interactions and lattice effects especially narrow-band systems. The first realizes the fractional quantum Hall effect using geometric frustration and ferromagnetism to obtain a nearly flat band with a large bandgap and non-zero Chern number. This system can support this effect at high tempera...

Geometric Phases and Topological Quantum Computation

In the first part of this review we introduce the basics theory behind geometric phases and emphasize their importance in quantum theory. The subject is presented in a general way so as to illustrate its wide applicability, but we also introduce a number of examples that will help the reader understand the basic issues involved. In the second part we show how to perform a universal quantum comp...
