The interplay between thermal and quantum fluctuations controls the competition between phases of matter in strongly correlated electron systems. We study finite-temperature properties of the strongly coupled two-dimensional doped Hubbard model using the minimally-entangled typical thermal states (METTS) method on width $4$ cylinders. We discover that a novel phase characterized by commensurate short-range antiferromagnetic correlations and no charge ordering occurs at temperatures above the… Expand

The Weak, the Strong and the Long Correlation Regimes of the Two-Dimensional Hubbard Model at Finite Temperature
We investigate the momentum-resolved spin and charge susceptibilities, as well as the chemical potential and double occupancy in the two-dimensional Hubbard model as functions of doping, temperatureExpand

In quantum materials, the electronic interaction and the electron-phonon coupling are, in general, two essential ingredients, the combined impact of which may drive exotic phases. Recently, anExpand


Strong coupling superconductivity, pseudogap, and Mott transition.
A unified perspective of this interplay between superconductivity, pseudogap, and Mott transition is provided in the two-dimensional Hubbard model within cellular dynamical mean-field theory on a 2×2 plaquette and using the continuous-time quantum Monte Carlo method as impurity solver. Expand
Numerical evidence of fluctuating stripes in the normal state of high-Tc cuprate superconductors
Dynamical stripe correlations in the three-band Hubbard model is demonstrated, which is robust to varying parameters, cluster size, and boundary conditions, and support the interpretation of experimental observations such as the hourglass magnetic dispersion and the Yamada plot of incommensurability versus doping in terms of the physics of fluctuating stripes. Expand
Stripe order from the perspective of the Hubbard model
A microscopic understanding of the strongly correlated physics of the cuprates must account for the translational and rotational symmetry breaking that is present across all cuprate families,Expand
How to detect fluctuating stripes in the high-temperature superconductors
We discuss fluctuating order in a quantum disordered phase proximate to a quantum critical point, with particular emphasis on fluctuating stripe order. Optimal strategies for extracting informationExpand
Topological order in the pseudogap metal
It is shown that a theory of a metal with topological order and emergent gauge fields can model much of the numerical data and derive a modified, nonperturbative version of the Luttinger theorem that holds in the Higgs phase. Expand
Two-temperature scales in the triangular-lattice Heisenberg antiferromagnet
The anomalous thermodynamic properties of the paradigmatic frustrated spin-1/2 triangular lattice Heisenberg antiferromagnet (TLH) has remained an open topic of research over decades, bothExpand
Pseudogap and antiferromagnetic correlations in the hubbard model.
The dynamical cluster approximation and quantum Monte Carlo simulations are used to calculate the single-particle spectra of the Hubbard model with next-nearest neighbor hopping and find that the pseudogap along the zone diagonal in the electron doped systems is due to long-range antiferromagnetic correlations.

Pseudogap, van Hove singularity, maximum in entropy, and specific heat for hole-doped Mott insulators
The first indication of a pseudogap in cuprates came from a sudden decrease of NMR Knight shift at a doping-dependent temperature $T^*(\delta)$. Since then, experiments have found phase transitionsExpand
Stripe order in the underdoped region of the two-dimensional Hubbard model
A stripe order that has a highly compressible wavelength on an energy scale of a few kelvin, with wavelength fluctuations coupled to pairing order is found, demonstrating the power of modern numerical methods to solve microscopic models, even in challenging settings. Expand
Simulation of the NMR response in the pseudogap regime of the cuprates
The temperature and doping evolution of these quantities on the two-dimensional Hubbard model using cluster dynamical mean field theory recovers the suppression of the Knight shift and the linear-in-T spin echo decay that increases with doping and suggests that the pseudogap is well described by strong short-range correlation effects.
