Topologically protected electron states arranged artificially in real space form a highly tunable emergent atomic chain. Engineered lattices in condensed matter physics, such as cold-atom optical lattices or photonic crystals, can have properties that are fundamentally different from those of naturally occurring electronic crystals. We report a novel type of artificial quantum matter lattice. Our lattice is a multilayer heterostructure built from alternating thin films of topological and… 
Tunable Dirac interface states in topological superlattices
Relativistic Dirac fermions are ubiquitous in condensed matter physics. Their mass is proportional to the material energy gap and the ability to control and tune the mass has become an essential tool
Topological nanomaterials
The past decade has witnessed the emergence of a new frontier in condensed matter physics: topological materials with an electronic band structure belonging to a different topological class from that
One-dimensional topological metal
We propose a new type of topological states of matter exhibiting topologically nontrivial edge states (ESs) within gapless bulk states (GBSs) protected by both spin rotational and reflection
Miniband engineering and topological phase transitions in topological-insulator–normal-insulator superlattices
Periodic stacking of topologically trivial and non-trivial layers with opposite symmetry of the valence and conduction bands induces topological interface states that, in the strong coupling limit,
Engineering Topological Superlattices and Phase Diagrams.
This orchestrated study shows how the electronic properties of topological superlattices evolve with unit-layer thicknesses and utilizes the weak antilocalization effect as a tool to gain quantitative insights into the evolution of conducting channels within each set of heterostructures.
Tunability of spin-dependent secondary topological interface states induced in an optical complex superlattice
The past decade has witnessed a booming development of topological photonics, which revolutionizes the methodology for controlling the behavior of light. A gigantic achievement is to engineer robust
Realization of photonic charge-2 Dirac point by engineering super-modes in topological superlattices
Quite recently, an unconventional variety of fourfold linear band degeneracy points has been discovered in certain condensed-matter systems. Contrary to standard 3-D Dirac monopoles, these quadruple
Controlling Topological States in Topological/Normal Insulator Heterostructures
The results for IV–VI compounds show the interface gap tunability by appropriately controlling the NI thickness, which can be explored for device design.
Topological photonic Tamm states and the Su-Schrieffer-Heeger model
In this paper we study the formation of topological Tamm states at the interface between a semi-infinite one-dimensional photonic-crystal and a metal. We show that when the system is topologically


Observation of a large-gap topological-insulator class with a single Dirac cone on the surface
Recent experiments and theories have suggested that strong spin–orbit coupling effects in certain band insulators can give rise to a new phase of quantum matter, the so-called topological insulator,
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.
Topological insulators, topological superconductors and Weyl fermion semimetals: discoveries, perspectives and outlooks
Unlike string theory, topological physics in lower dimensional condensed matter systems is an experimental reality since the bulk-boundary correspondence can be probed experimentally in lower
Three-Dimensional Topological Insulators
Topological insulators in three dimensions are nonmagnetic insulators that possess metallic surface states (SSs) as a consequence of the nontrivial topology of electronic wavefunctions in the bulk of
Topological insulators and superconductors
Topological insulators are new states of quantum matter which cannot be adiabatically connected to conventional insulators and semiconductors. They are characterized by a full insulating gap in the
Colloquium : Topological insulators
Topological insulators are electronic materials that have a bulk band gap like an ordinary insulator but have protected conducting states on their edge or surface. These states are possible due to
Observation of quantum-tunnelling-modulated spin texture in ultrathin topological insulator Bi2Se3 films.
Understanding the spin-texture behaviour of boundary modes in ultrathin topological insulator films is critically essential for the design and fabrication of functional nanodevices. Here, by using
Weyl semimetal in a topological insulator multilayer.
The Weyl semimetal has a nonzero dc conductivity at zero temperature, but Drude weight vanishing as T(2), and is thus an unusual metallic phase, characterized by a finite anomalous Hall conductivity and topologically protected edge states.

This graduate-level textbook is the first pedagogical synthesis of the field of topological insulators and superconductors, one of the most exciting areas of research in condensed matter physics.
Topological insulators in Bi2Se3, Bi2Te3 and Sb2Te3 with a single Dirac cone on the surface
Topological insulators are new states of quantum matter in which surface states residing in the bulk insulating gap of such systems are protected by time-reversal symmetry. The study of such states
