Intra-unit-cell electronic nematicity of the high-Tc copper-oxide pseudogap states
The determination of a quantitative order parameter representing intra-unit-cell nematicity: the breaking of rotational symmetry by the electronic structure within each CuO2 unit cell is reported.
Direct phase-sensitive identification of a d-form factor density wave in underdoped cuprates
It is demonstrated by direct sublattice phase-resolved visualization that the density wave found in underdoped cuprates consists of modulations of the intraunit-cell states that exhibit a predominantly d-symmetry form factor.
Graphene as an electronic membrane
We investigate the membrane aspect of graphene and its impact on the electronic properties. We show that rippling generates spatially varying electrochemical potential that is proportional to the
Theory of stripes in quasi-two-dimensional rare-earth tellurides
Even though the rare-earth tritellurides are tetragonal materials with a quasi-two-dimensional band structure, they have a ``hidden'' one-dimensional character. The resultant near-perfect nesting of
Spectroscopic Imaging Scanning Tunneling Microscopy Studies of Electronic Structure in the Superconducting and Pseudogap Phases of Cuprate High-Tc Superconductors
One of the key motivations for the development of atomically resolved spectroscopic imaging scanning tunneling microscopy (SI-STM) has been to probe the electronic structure of cuprate high
Topological superconductivity in monolayer transition metal dichalcogenides
This work identifies monolayer hole-doped transition metal dichalcogenide (TMD)s as candidates for topological superconductors out of such momentum-space-split spinless fermions and proposes that the unusual spin-valley locking in hole- doped TMDs together with repulsive interactions selectively favours two topologicalsuperconducting states.
Topological Defects Coupling Smectic Modulations to Intra–Unit-Cell Nematicity in Cuprates
A Ginzburg-Landau functional is proposed and demonstrated how it can explain the coexistence of the smectic and intra–unit-cell broken symmetries and also correctly predict their interplay at the atomic scale.
Dirac spin-orbit torques and charge pumping at the surface of topological insulators
We address the nature of spin-orbit torques at the magnetic surfaces of topological insulators using the linear-response theory. We find that the so-called Dirac torques in such systems possess a
Stability of half-quantum vortices in p(x)+ip(y) superconductors.
This work considers the stability conditions for half-quantum vortices in a quasi-two-dimensional p{x}+ip{y} superconductor (such as Sr2RuO4) and proposes using various mesoscopic geometries to stabilize and observe these exotic excitations.
Manipulating superconductivity in ruthenates through Fermi surface engineering
The key challenge in superconductivity research is to go beyond the historical mode of discovery-driven research. We put forth a new strategy, which is to combine theoretical developments in the
