Weak Fragmentation and Thermalization in a Dipole-Conserving Bose-Hubbard Chain
Chenrong Liu
We study Hilbert-space fragmentation and thermalization in a one-dimensional dipole-conserving Bose-Hubbard chain. By analyzing the structure of the Hamiltonian matrix in the Fock…
Photon-Atom Granularity Noise Thermometry
Chen-Rong Liu, Yixuan Wang, Xiaowei Wang +5
We propose granularity noise thermometry (GNT), a fluctuation-based optical thermometry scheme that exploits the intrinsic fluctuations of susceptibility arising from atomic discre…
Granularity Noise Limit in Atomic-Ensemble-Based Metrology
Chen-Rong Liu, Chuang Li, Runxia Tao +4
Conventional noise analysis in atomic-ensemble sensing assumes a continuous-medium approximation, thereby treating the atomic system as a deterministic dielectric. Here, we demonst…
Noise-Resilient Quantum Metrology with Quantum Computing
Xiangyu Wang, Chenrong Liu, Xue Lin +8
Quantum computing has made remarkable strides in recent years, as demonstrated by quantum supremacy experiments and the realization of high-fidelity, fault-tolerant gates. However,…
Fisher-Based Sensitivity Framework for Rydberg Atom Microwave Electrometry
Chen-Rong Liu, Runxia Tao, Xiang Lv +4
Fisher information provides a rigorous theoretical benchmark for evaluating quantum sensor sensitivity; however, a comprehensive framework for quantifying the fundamental limits of…
Beyond Conventional Pairing: Bosonic Quartic Superfluidity, Exotic XY Magnetism, and Phase Criticality
Chenrong Liu, Zhi Lin
We report two unprecedented bosonic quartic superfluid (BQSF) phases in binary boson mixtures with synthetic pair-hopping (SPH) interaction realizable through Floquet engineering,…
Ground-state phase diagram of two-component interacting bosons on a two-leg ladder
Po Chen, Chenrong Liu
Using the cluster Gutzwiller mean-field method, we numerically study the ground-state phase diagram of the non-hard-core two-component interacting bosons trapped in a two-leg ladde…
Ground state properties of a multi-component bosonic mixture: a Gutzwiller mean-field study
Chenrong Liu, Po Chen, Linli He +1
Using the single-site Gutzwiller method, we theoretically study the ground state and the interspecies entanglement properties of interexchange symmetric multi-component (two- and t…
Generalized effective-potential Landau theory for a tunable state-dependent hexagonal optical lattice
Sheng Yue, Dan-Yang Chen, Chenrong Liu +2
We analytically study the ground-state phase diagrams of ultracold bosons with various values of the effective magnetic quantum number in a state-dependent hexagonal optical la…
Phase diagram of the two-component bosonic system with pair hopping in synthetic dimension
Chenrong Liu, Zhi Lin
We systematically study the ground-state phase diagrams and the demixing effect of a two-dimensional two-component bosonic system with pair hopping in synthetic dimension by using…
Enhancement of boson superfluidity in a one-dimensional Bose-Fermi mixture
Chenrong Liu, Yongzheng Wu, Jie Lou +1
We examine the effect of boson-fermion interaction in a one-dimensional Bose-Fermi mixture by using the density matrix renormalization group method. We show that the boson superflu…
Novel quantum phases of two-component bosons with pair hopping in synthetic dimension
Zhi Lin, Chenrong Liu, Yan Chen
We study two-component (or pseudospin-1/2) bosons with pair hopping interactions in synthetic dimension, for which a feasible experimental scheme on a square optical lattice is als…
Temperature-dependent spectral function of a Kondo impurity in an -wave superconductor
Chenrong Liu, Yixuan Huang, Yan Chen +1
Using the numerical renormalization group method, the effect due to a Kondo impurity in an -wave superconductor is examined at finite temperature (). The -behaviors of the…

Zheng Yan, Yongzheng Wu, Chenrong Liu +3
Quantum spin systems with strong geometric restrictions give rise to rich quantum phases such as valence bond solids and spin liquid states. However, the geometric restrictions oft…
