Emergent relativistic symmetry from interacting fermions on the honeycomb bilayer
Zi Hong Liu, Lukas Janssen
We study the phase diagram of interacting spinless fermions on the honeycomb bilayer at charge neutrality using large-scale quantum Monte Carlo simulations. In the noninteracting l…
Critical properties of metallic and deconfined quantum phase transitions in Dirac systems
Zi Hong Liu, Matthias Vojta, Fakher F. Assaad +1
We characterize, by means of large-scale fermion quantum Monte Carlo simulations, metallic and deconfined quantum phase transitions in a bilayer honeycomb model in terms of their q…
Disorder Operator and Rényi Entanglement Entropy of Symmetric Mass Generation
Zi Hong Liu, Yuan Da Liao, Gaopei Pan +8
In recent years a consensus has gradually been reached that the previously proposed deconfined quantum critical point (DQCP) for spin-1/2 systems, an archetypal example of quantum…
Marginal Fermi liquid at magnetic quantum criticality from dimensional confinement
Bernhard Frank, Zi Hong Liu, Fakher F. Assaad +2
Metallic quantum criticality is frequently discussed as a source for non-Fermi liquid behavior, but controlled theoretical treatments are scarce. Here we identify and study a novel…
Fermion disorder operator at Gross-Neveu and deconfined quantum criticalities
Zi Hong Liu, Weilun Jiang, Bin-Bin Chen +5
The fermion disorder operator has been shown to reveal the entanglement information in 1D Luttinger liquids and 2D free and interacting Fermi and non-Fermi liquids emerging at quan…
Magnetic quantum phase transition in a metallic Kondo heterostructure
Zi Hong Liu, Bernhard Frank, Lukas Janssen +2
We consider a two-dimensional quantum spin system described by a Heisenberg model that is embedded in a three-dimensional metal. The two systems couple via an antiferromagnetic Kon…
Many versus one: the disorder operator and entanglement entropy in fermionic quantum matter
Weilun Jiang, Bin-Bin Chen, Zi Hong Liu +5
Motivated by recent development of the concept of the disorder operator and its relation with entanglement entropy in bosonic systems, here we show the disorder operator successful…
Metallic and Deconfined Quantum Criticality in Dirac Systems
Zi Hong Liu, Matthias Vojta, Fakher F. Assaad +1
Motivated by the physics of spin-orbital liquids, we study a model of interacting Dirac fermions on a bilayer honeycomb lattice at half filling, featuring an explicit global SO(3)$…
Revealing Fermionic Quantum Criticality from New Monte Carlo Techniques
Xiao Yan Xu, Zi Hong Liu, Gaopei Pan +3
This review summarizes recent developments in the study of fermionic quantum criticality, focusing on new progress in numerical methodologies, especially quantum Monte Carlo method…
Itinerant Quantum Critical Point with Fermion Pockets and Hot Spots
Zi Hong Liu, Gaopei Pan, Xiao Yan Xu +2
Metallic quantum criticality is among the central theme in the understanding of correlated electronic systems, and converging results between analytical and numerical approaches ar…
EMUS-QMC: Elective Momentum Ultra-Size Quantum Monte Carlo Method
Zi Hong Liu, Xiao Yan Xu, Yang Qi +2
One bottleneck of quantum Monte Carlo (QMC) simulation of strongly correlated electron systems lies at the scaling relation of computational complexity with respect to the system s…
Itinerant quantum critical point with frustration and non-Fermi-liquid
Zi Hong Liu, Xiao Yan Xu, Yang Qi +2
Employing the self-learning quantum Monte Carlo algorithm, we investigate the frustrated transverse-field triangle-lattice Ising model coupled to a Fermi surface. Without fermions,…
