Charge transport properties of spin-orbit coupled materials in different correlation regimes

From recent advances in solid state physics, a novel material classification scheme has evolved which is based on the concept of topology and provides an understanding of different phenomena ranging from quantum transport to unusual flavors of superconduct ...

Band and Correlated Insulators of Cold Fermions in a Mesoscopic Lattice

Jean-Philippe Brantut, Thierry Giamarchi, Samuel Häusler

We investigate the transport properties of neutral, fermionic atoms passing through a one-dimensional quantum wire containing a mesoscopic lattice. The lattice is realized by projecting individually controlled, thin optical barriers on top of a ballistic c ...

Topological phase transitions driven by strain in monolayer tellurium

Oleg Yazyev, Quansheng Wu, Wei Zhang

Two-dimensional (2D) Xenes of a single type of element can offer fascinating electronic properties, such as massless Dirac fermions for extremely high charge-carrier mobility and topological insulators for dissipationless electron transport. However, the r ...

Spectroscopic Studies of the Electronic Structure in Layered Cuprates and Ruthenates

Claudia Giuseppina Fatuzzo

In materials where electrons interact strongly, a number of exotic and exciting phenomena arise. The mechanisms at the base of many of these phenomena remain debated, as strongly correlated electron physics represents one of the biggest challenges for mode ...

Spin-resolved band structure of a densely packed Pb monolayer on Si(111)

Jan Hugo Dil, Stefan Peter Muff, Mauro Fanciulli

Monolayer structures of Pb on Si(111) attracted recently considerable interest as superconductivity was found in these truly two-dimensional (2D) structures. In this study, we analyzed the electronic surface band structure of the so-called striped incommen ...

Evolution of the Fermi surface of BiTeCl with pressure

Helmuth Berger

We report measurements of Shubnikov-de Haas oscillations in the giant Rashba semiconductor BiTeCl under applied pressures up to similar to 2.5 GPa. We observe two distinct oscillation frequencies, corresponding to the Rashba-split inner and outer Fermi sur ...

Strong paramagnon scattering in single atom Pd contacts

Klaus Kern, Markus Ternes, Uta Schlickum, Peter Wahl, Ivan Pentegov, Verena Katharina Schendel

Among all transition metals, palladium (Pd) has the highest density of states at the Fermi energy at low temperatures yet does not fulfill the Stoner criterion for ferromagnetism. However, close proximity to magnetism renders it a nearly ferromagnetic meta ...

Pressure-tuned Transport Properties of Novel Iron-based Superconductors and Topological Insulators

Andrea Pisoni

The majority of interactions in solids strongly depend on the interatomic distances. The application of pressure changes the lattice parameters and modifies the electronic and the phononic energy spectra of a material avoiding some of the undesirable effec ...

Chiral Spin Liquids in Triangular-LatticeSU(N)Fermionic Mott Insulators with Artificial Gauge Fields

Frédéric Mila, Karlo Penc, Pierre Marcel Nataf, Miklos Lajko

We show that, in the presence of a π/2 artificial gauge field per plaquette, Mott insulating phases of ultracold fermions with SU(N) symmetry and one particle per site generically possess an extended chiral phase with intrinsic topological order characteri ...
