A new algorithm of quantum Monte Carlo simulations designed to detect very weak magnetic order allows high-resolution studies of the correlation between magnetic order and electrical insulation in Mott insulators. Specific investigations of the Hubbard model on honeycomb lattice---a paradigmatic model for Mott insulators---show that the correlation emerges through a continuous quantum phase transition belonging to a new universality class.

Charge Order in the Holstein Model on a Honeycomb Lattice.
TLDR
It is shown that Dirac fermions give rise to charge-density-wave (CDW) order and present evidence that this occurs only above a finite critical interaction strength, and the temperature for the transition into the CDW which can occur at finite values owing to the discrete nature of the broken symmetry.

Semi-Metal-Insulator Transition of the Hubbard Model in the Honeycomb Lattice
Using quantum Monte Carlo and finite-size scaling for the Hubbard model, we find evidence of a zero-temperature transition between the nonmagnetic semi-metal and an antiferromagnetic insulator in the
Interactions and phase transitions on graphene's honeycomb lattice.
TLDR
The Hubbard model in the large-N limit is shown to have a semimetal-antiferromagnetic insulator quantum critical point in the universality class of the Gross-Neveu model, and its consequences for various physical quantities are examined.
Relativistic Mott criticality in graphene
We formulate the effective Gross-Neveu-Yukawa theory of the semimetal-insulator transitions on the honeycomb lattice and compute its quantum critical behavior near three (spatial) dimensions. We find

TLDR
The data suggest that the nonmagnetic ground state of the half-filled staggered-flux Hubbard model is a possible candidate for the putative algebraic spin liquid.
Absence of a Spin Liquid Phase in the Hubbard Model on the Honeycomb Lattice
TLDR
By performing numerically exact quantum Monte Carlo simulations, this work extends the previous study to much larger clusters, and finds, if any, a very weak evidence of this spin liquid region, and indicates a direct and continuous quantum phase transition between SM and AFMI.

TLDR
In the quantum spin-Hall state the Kane-Mele model supplemented by a Hubbard U term is considered, and the spin, charge, and single-particle dynamics of the helical Luttinger liquid is studied by retaining the Hubbard interaction only on a ribbon edge.

We investigate the Hubbard model on the honeycomb lattice with intrinsic spin orbit interactions as a paradigm for two-dimensional topological band insulators in the presence of interactions.
Quantum spin liquid emerging in two-dimensional correlated Dirac fermions
TLDR
It is shown, by means of large-scale quantum Monte Carlo simulations of correlated fermions on a honeycomb lattice (a structure realized in, for example, graphene), that a quantum spin liquid emerges between the state described by massless Dirac fermion and an antiferromagnetically ordered Mott insulator.
