Ultracold and quantum degenerate gases held near conductive surfaces can serve as sensitive, high resolution, and wide-area probes of electronic current flow. Previous work has imaged transport around grain boundaries in a gold wire by using ultracold and Bose-Einstein condensed atoms held microns from the surface with an atom chip trap. We show that atom chip microscopy may be applied to useful purpose in the context of materials exhibiting topologically protected surface transport. Current…

Microscopic imaging of local magnetic fields provides a window into the organizing principles of complex and technologically relevant condensed matter materials. However, a wide variety of intriguing

Trapping ultracold gases near cryogenic materials with rapid reconfigurability

We demonstrate an atom chip trapping system that allows the placement and high-resolution imaging of ultracold atoms within microns from any ≲100 μm-thin, UHV-compatible material, while also allowing

Identifying topological edge states in 2D optical lattices using light scattering

We recently proposed in a Letter [Phys. Rev. Lett. 108, 255303] a novel scheme to detect topological edge states in an optical lattice, based on a generalization of Bragg spectroscopy. The scope of

Symmetry protected Josephson supercurrents in three-dimensional topological insulators.

It is shown that the supercurrent is largely carried by surface states, due to the inherent topology of the bands, and that it is robust against disorder, which clarifies key open issues regarding the nature of supercurrents in topological insulators.

Imaging current distribution in a topological insulator Bi2Se3 in the presence of competing surface and bulk contributions to conductivity

A temperature dependent competition between surface and bulk conductivity produces a temperature dependent variation in uniformity of current flow in the topological insulator.

High-resolution imaging of ultracold fermions in microscopically tailored optical potentials

We report on the local probing and preparation of an ultracold Fermi gas on the length scale of one micrometer, i.e. of the order of the Fermi wavelength. The essential tool of our experimental setup

Surface state transport and ambipolar electric field effect in Bi₂Se₃ nanodevices.

Electronic transport measurements on thin Bi2Se3 devices are reported and it is shown that the density of the surface states can be modulated via the electric field effect by using a top-gate with a high-k dielectric insulator.

Long-Range Order in Electronic Transport Through Disordered Metal Films

In polycrystalline metal (gold) films, long-range correlations forming organized patterns oriented at ±45° relative to the mean current flow are observed, enabling new insight into the interplay between disorder and transport.

Topological surface states protected from backscattering by chiral spin texture

It is demonstrated that the chiral nature of these states protects the spin of the carriers, potentially useful for spin-based electronics, in which long spin coherence is critical, and also for quantum computing applications, where topological protection can enable fault-tolerant information processing.

Atom chips with two-dimensional electron gases: Theory of near-surface trapping and ultracold-atom microscopy of quantum electronic systems

We show that current in a two-dimensional electron gas (2DEG) can trap ultracold atoms <1 {mu}m away with orders of magnitude less spatial noise than a metal trapping wire. This enables the creation

Bulk band gap and surface state conduction observed in voltage-tuned crystals of the topological insulator Bi2Se3.

A transport study of exfoliated few monolayer crystals of topological insulator Bi2Se3 in an electric field effect geometry finds that the temperature T and magnetic field dependent transport properties in the vicinity of this V(g) can be explained by a bulk channel with activation gap of approximately 50 meV and a relatively high-mobility metallic channel that dominates at low T.

Microscopic magnetic traps for neutral atoms.

These geometries are well-suited for fabrication from superconductors using standard microfabrication techniques and should exhibit interesting optical behavior, since their spatial extent would be less than the resonant light wavelength.
