Superconductivity and non-Fermi liquid behavior near a nematic quantum critical point
Samuel Lederer, Yoni Schattner, Erez Berg +1
Using determinantal quantum Monte Carlo, we compute the properties of a lattice model with spin itinerant electrons tuned through a quantum phase transition to an Ising…
The Hall number across a van Hove singularity
Akash V. Maharaj, Ilya Esterlis, Yi Zhang +2
In the context of the relaxation time approximation to Boltzmann transport theory, we examine the behavior of the Hall number, , of a metal in the neighborhood of a Lifshitz t…
Intertwined Order in a Frustrated 4-leg Cylinder
John F. Dodaro, Hong-Chen Jiang, Steven A. Kivelson
We report a density-matrix renormalization group study of the - model with nearest ( & ) and next-nearest ( & ) interactions on a 4-leg cylinder with conc…
Fractional charge and emergent mass hierarchy in diagonal two-leg t-J cylinders
Yi-Fan Jiang, Hong-Chen Jiang, Hong Yao +1
We define a new class of "diagonal" t-J ladders rotated by /4 relative to the canonical lattice directions of the square lattice, and study it using density matrix renormalizati…
Non-quasiparticle transport and resistivity saturation: A view from the large-N limit
Yochai Werman, Steven A. Kivelson, Erez Berg
The electron dynamics in metals are usually well described by the semiclassical approximation for long-lived quasiparticles. However, in some metals, the scattering rate of the ele…
Ideal charge density wave order in the high-field state of superconducting YBCO
H. Jang, W. -S. Lee, H. Nojiri +20
The existence of charge density wave (CDW) correlations in cuprate superconductors has now been established. However, the nature of the ground state order has remained uncertain be…
