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…
