Dynamical localization transition of string breaking in quantum spin chains
Roberto Verdel, Guo-Yi Zhu, Markus Heyl
The fission of a string connecting two charges is an astounding phenomenon in confining gauge theories. The dynamics of this process have been studied intensively in recent years,…
Structured volume-law entanglement in an interacting, monitored Majorana spin liquid
Guo-Yi Zhu, Nathanan Tantivasadakarn, Simon Trebst
Monitored quantum circuits allow for unprecedented dynamical control of many-body entanglement. Here we show that random, measurement-only circuits, implementing the competition of…
Nishimori's cat: stable long-range entanglement from finite-depth unitaries and weak measurements
Guo-Yi Zhu, Nathanan Tantivasadakarn, Ashvin Vishwanath +2
In the field of monitored quantum circuits, it has remained an open question whether finite-time protocols for preparing long-range entangled states lead to phases of matter which…
Topological fracton quantum phase transitions by tuning exact tensor network states
Guo-Yi Zhu, Ji-Yao Chen, Peng Ye +1
Gapped fracton phases of matter generalize the concept of topological order and broaden our fundamental understanding of entanglement in quantum many-body systems. However, their a…
Subdiffusive dynamics and critical quantum correlations in a disorder-free localized Kitaev honeycomb model out of equilibrium
Guo-Yi Zhu, Markus Heyl
Disorder-free localization has recently emerged as a mechanism for ergodicity breaking in homogeneous lattice gauge theories. In this work we show that this mechanism can lead to u…
Spatiotemporal dynamics of particle collisions in quantum spin chains
P. I. Karpov, G. -Y. Zhu, M. P. Heller +1
Recent developments have highlighted the potential of quantum spin models to realize the phenomenology of confinement leading to the formation of bound states such as mesons. In th…
Gapless Coulomb state emerging from a self-dual topological tensor-network state
Guo-Yi Zhu, Guang-Ming Zhang
In the tensor network representation, a deformed topological ground state wave function is proposed and its norm can be exactly mapped to the two-dimensional solvable Ashki…
Spin-valley antiferromagnetism and topological superconductivity in the trilayer graphene Moire super-lattice
Guo-Yi Zhu, Tao Xiang, Guang-Ming Zhang
Exotic correlated insulating phases emerge in the ABC-stacked trilayer graphene-boron nitride Moire super-lattice at both quarter and half-filling. A single-band minimal model with…
Inter-valley spiral order in the Mott insulating state of a heterostructure of trilayer graphene-boron nitride
Guo-Yi Zhu, Tao Xiang, Guang-Ming Zhang
Recent experiment has shown that the ABC-stacked trilayer graphene-boron nitride Moire super-lattice at half-filling is a Mott insulator. Based on symmetry analysis and effective b…
Decoding quantum criticalities from fermionic/parafermionic topological states
Zi-Qi Wang, Guo-Yi Zhu, Guang-Ming Zhang
Under an appropriate symmetric bulk bipartition in a one-dimensional symmetry protected topological phase with the Affleck-Kennedy-Lieb-Tasaki matrix product state wave function fo…
Plaquette-centered rotation symmetry and octet-nodal superconductivity in
Guo-Yi Zhu, Guang-Ming Zhang
A plaquette-centered rotation symmetry is identified to play a significant role in determining and stabilizing the Fermi-surface structure of Fe-based superconductors.…
Topological phase transition from nodal to nodeless d-wave superconductivity in electron-doped cuprate superconductors
Guo-Yi Zhu, Guang-Ming Zhang
Unlike the hole-doped cuprates, both nodal and nodeless superconductivity (SC) are observed in the electron-doped cuprates. To understand these two types of SC states, we propose a…
