We study the Mott transition in a frustrated Hubbard model with next-nearest neighbor hopping at half-filling. The interplay between interaction, dimensionality, and geometric frustration closes the one-dimensional Mott gap and gives rise to a metallic phase with Fermi surface pockets. We argue that they emerge as a consequence of remnant one-dimensional umklapp scattering at the momenta with vanishing interchain hopping matrix elements. In this pseudogap phase, enhanced d-wave pairing…

Pseudogap-to-metal transition in the anisotropic two-dimensional Hubbard model
• Physics
• 2017
The transition between a metallic and a pseudogap phase in high-$T_c$ cuprate superconductors is the subject of experimental investigations but has not been settled theoretically, even within the
Thermodynamics and magnetism in the two-dimensional to three-dimensional crossover of the Hubbard model
• Physics
• 2020
The realization of antiferromagnetic (AF) correlations in ultracold fermionic atoms on an optical lattice is a significant achievement. Experiments have been carried out in one, two, and three
Equivalence of Rashba-Hubbard and Hubbard chains

We review the fact that U(1) gauge symmetry enables the mapping of one-dimensional Hubbard chains with Rashba-type spin orbit coupling to renormalized Hubbard Hamiltonians. The existence of the

AbstractWe report systematic studies of a new quasi-one-dimensional (quasi-1D) compound, Ba3TiTe5, and the high-pressure induced superconductivity therein. Ba3TiTe5 was synthesized at high pressure
Multi-orbital physics in lithium-molybdenum purple-bronze: going beyond paradigm
Abstract We investigate the role of inter-orbital fluctuations in the low energy physics of a quasi-1D material – lithium molybdenum purple bronze (LMO). It is an exceptional material that may
