Theory of High Temperature Superconductivity: A Status Report
This talk briefly reviews the current experimental and theoretical developments in high Tcsuperconductivity, focusing on the pseudogap regime of the underdoped region of the phase diagram. We argue that the appea...

Selective scattering between Floquet–Bloch and Volkov states in a topological insulator
Time- and angle-resolved photoelectron spectroscopy experiments are used to monitor the transition between Floquet–Bloch and Volkov states in the topological insulator Bi2Se3.

Direct optical detection of Weyl fermion chirality in a topological semimetal
Measuring the photocurrent response to circularly polarized mid-infrared light provides direct access to the chirality of Weyl fermions in Weyl semimetals — the property responsible for a range of exotic pheno...

Evidence for quantum spin liquid behaviour in single-layer 1T-TaSe2 from scanning tunnelling microscopy
Two-dimensional triangular-lattice antiferromagnets are predicted under some conditions to exhibit a quantum spin liquid ground state with no energy barrier to create emergent, fractionalized spinon excitation...

Evidence for a spinon Kondo effect in cobalt atoms on single-layer 1T-TaSe2
Quantum spin liquids are highly entangled, disordered magnetic states that are expected to arise in frustrated Mott insulators and to exhibit exotic fractional excitations such as spinons and chargons. Despite...
