We develop a nonequilibrium increment method in quantum Monte Carlo simulations to obtain the Rényi entanglement entropy of various quantum many-body systems with high …
Novel critical phenomena beyond the Landau-Ginzburg-Wilson paradigm have been long sought after. Among many candidate scenarios, the deconfined quantum critical point …
We study disorder operator, defined as a symmetry transformation applied to a finite region, across a continuous quantum phase transition in (2+ 1) d. We show analytically that, at a …

Lieb lattice has been predicted to host various exotic electronic properties due to its unusual Dirac-flat band structure. However, the realization of a Lieb lattice in a real material is still …
We present quantum Monte Carlo simulations for the chiral Heisenberg Gross-Neveu- Yukawa quantum phase transition of relativistic fermions with N= 4 Dirac spinor components …

Using large-scale quantum Monte Carlo simulations, we determine the ground state phase diagram of the spin-1/2 antiferromagnetic Heisenberg model on the honeycomb lattice for …
The hunt for exotic quantum phase transitions described by emergent fractionalized degrees of freedom coupled to gauge fields requires a precise determination of the fixed point …
