Cuprate superconductors as viewed through a striped lens
JM Tranquada - Advances in Physics, 2020 - Taylor & Francis
Understanding the electron pairing in hole-doped cuprate superconductors has been a
challenge, in particular because the “normal” state from which it evolves is unprecedented …

Chiral phonons in the pseudogap phase of cuprates
The nature of the pseudogap phase of cuprates remains a major puzzle,. One of its
signatures is a large negative thermal Hall conductivity, whose origin is as yet unknown …

Competing stripe and magnetic phases in the cuprates from first principles
Realistic description of competing phases in complex quantum materials has proven
extremely challenging. For example, much of the existing density-functional-theory-based …

Charge density waves in cuprate superconductors beyond the critical doping
The unconventional normal-state properties of the cuprates are often discussed in terms of
emergent electronic order that onsets below a putative critical doping of xc≈ 0.19. Charge …

From the pseudogap metal to the Fermi liquid using ancilla qubits
We propose a new parton theory of the hole-doped cuprates, describing the evolution from

Resonant thermal Hall effect of phonons coupled to dynamical defects
We present computations of the thermal Hall coefficient of phonons scattering off a defect
with multiple energy levels. Using a microscopic formulation based on the Kubo formula, we …
