Spin liquids in frustrated magnets
TLDR
This exotic behaviour of frustrated magnets is now being uncovered in the laboratory, providing insight into the properties of spin liquids and challenges to the theoretical description of these materials.
Topological invariants of time-reversal-invariant band structures
The topological invariants of a time-reversal-invariant band structure in two dimensions are multiple copies of the $\mathbb{Z}_2$ invariant found by Kane and Mele. Such invariants protect the
Deconfined Quantum Critical Points
TLDR
It is shown that near second-order quantum phase transitions, subtle quantum interference effects can invalidate this paradigm for quantum criticality, and a theory of quantum critical points in a variety of experimentally relevant two-dimensional antiferromagnets is presented.
Quantum criticality beyond the Landau-Ginzburg-Wilson paradigm
We present the critical theory of a number of zero-temperature phase transitions of quantum antiferromagnets and interacting boson systems in two dimensions. The most important example is the
Weyl semimetal in a topological insulator multilayer.
TLDR
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.
Topological nodal semimetals
We present a study of “nodal-semimetal” phases in which nondegenerate conduction and valence bands touch at points (the “Weyl semimetal”) or lines (the “line-node semimetal”) in three-dimensional
Quantum Excitations in Quantum Spin Ice
Recent work has highlighted remarkable effects of classical thermal fluctuations in the dipolar spin ice compounds, such as ‘‘artificial magnetostatics,’’ manifesting as Coulombic power-law spin

TLDR
This review discusses the nature of such phases and their properties based on paradigmatic models and general arguments, and introduces theoretical technology such as gauge theory and partons, which are conveniently used in the study of quantum spin liquids.
Correlated Quantum Phenomena in the Strong Spin-Orbit Regime
We discuss phenomena arising from the combined influence of electron correlation and spin-orbit coupling (SOC), with an emphasis on emergent quantum phases and transitions in heavy transition metal
Carbon nanotube intramolecular junctions
The ultimate device miniaturization would be to use individual molecules as functional devices. Single-wall carbon nanotubes (SWNTs) are promising candidates for achieving this: depending on their
