Critical polynomials in the nonplanar and continuum percolation models
Wenhui Xu, Junfeng Wang, Hao Hu +1
Exact or precise thresholds have been intensively studied since the introduction of the percolation model. Recently the critical polynomial was introduced for plan…
Bypassing the computational bottleneck of quantum-embedding theories for strong electron correlations with machine learning
John Rogers, Tsung-Han Lee, Sahar Pakdel +5
A cardinal obstacle to performing quantum-mechanical simulations of strongly-correlated matter is that, with the theoretical tools presently available, sufficiently-accurate comput…
Quantum Critical Point revisited by the Dynamical Mean Field Theory
Wenhu Xu, Gabriel Kotliar, Alexei M. Tsvelik
Dynamical mean field theory is used to study the quantum critical point (QCP) in the doped Hubbard model on a square lattice. The QCP is characterized by a universal scaling form o…
Giant Spin Gap and Magnon Localization in the Disordered Heisenberg Antiferromagnet Sr2Ir1-xRuxO4
Yue Cao, Xuerong Liu, Wenhu Xu +15
We study the evolution of magnetic excitations in the disordered two-dimensional antiferromagnet Sr2Ir1-xRuxO4. A gigantic magnetic gap greater than 40 meV opens at x = 0.27 and in…
Highly Dispersive Electron Relaxation and Colossal Thermoelectricity in the Correlated Semiconductor FeSb
Peijie Sun, Wenhu Xu, Jan M. Tomczak +4
We show that the colossal thermoelectric power, , observed in the correlated semiconductor FeSb below 30\,K is accompanied by a huge Nernst coefficient and magneto…
Hidden Fermi Liquid, Scattering Rate Saturation and Nernst Effect: a DMFT Perspective
Wenhu Xu, Kristjan Haule, Gabriel Kotliar
We investigate the transport properties of a correlated metal within dynamical mean field theory. Canonical Fermi liquid behavior emerges only below a very low temperature scale $T…
High frequency thermoelectric response in correlated electronic systems
Wenhu Xu, Cédric Weber, Gabriel Kotliar
We derive a general formalism for evaluating the high-frequency limit of the thermoelectric power of strongly correlated materials, which can be straightforwardly implemented in av…
