Microwave electrometry with quantum-limited resolutions in a Rydberg atom array
Yao-Wen Zhang, De-Sheng Xiang, Ren Liao +6
Microwave (MW) field sensing is foundational to modern technology, yet its evolution, reliant on classical antennas, is constrained by fundamental physical limits on field, tempora…
Observation of non-Hermitian many-body phase transition in a Rydberg-atom array
Yao-Wen Zhang, Biao Xu, Yijia Zhou +8
Non-Hermitian quantum mechanics with parity-time (PT) symmetry offers a powerful framework for exploring the complex interplay of dissipation and coherent interactions in open quan…
Diagnosing Quantum Many-body Chaos in Non-Hermitian Quantum Spin Chain via Krylov Complexity
Yijia Zhou, Wei Xia, Lin Li +1
We investigate the phase transitions from chaotic to nonchaotic dynamics in a quantum spin chain with a local non-Hermitian disorder, which can be realized with a Rydberg atom arra…
Tunable atom-cavity interactions with configurable atomic chains
Xinwei Li, Yijia Zhou, Hao Zhang
We investigate atomic chains with different spatial configurations coupled to a ring cavity comprising two counterpropagating traveling modes. We describe the collective atom-light…
Interference of cavity light by a single atom acting as a double slit
Yijia Zhou, Xinwei Li, Weibin Li +1
Young's double-slit interference experiment is central to quantum mechanics. While it has been demonstrated that an array of atoms can produce interference in light, it is a fundam…
A multi-band atomic candle with microwave-dressed Rydberg atoms
Yafen Cai, Shuai Shi, Yijia Zhou +7
Stabilizing important physical quantities to atom-based standards lies at the heart of modern atomic, molecular and optical physics, and is widely applied to the field of precision…
Multipolar Fermi-surface deformation in a Rydberg-dressed Fermi gas with long-range anisotropic interactions
Yijia Zhou, Rejish Nath, Haibin Wu +2
We study theoretically the deformation of the Fermi surface (FS) of a three-dimensional gas of Rydberg-dressed Li atoms. The laser dressing to high-lying Rydberg states res…
Observation of collectivity enhanced magnetoassociation of Li in the quantum degenerate regime
Vineetha Naniyil, Yijia Zhou, Guy Simmonds +3
The association process of Feshbach molecules is well described by a Landau-Zener (LZ) transition above the Fermi temperature, such that two-body physics dominates the dynamics. Ho…
Quench dynamics of Rydberg-dressed bosons on two-dimensional square lattices
Yijia Zhou, Yongqiang Li, Rejish Nath +1
We study the dynamics of bosonic atoms on a two-dimensional square lattice, where atomic interactions are long-ranged with either a box or soft-core shape. The latter can be realiz…
Controlling the dynamical scale factor in a trapped atom Sagnac Interferometer
Yijia Zhou, Igor Lesanovsky, Thomas Fernholz +1
Sagnac interferometers with massive particles promise unique advantages in achieving high precision measurements of rotation rates over their optical counterparts. Recent proposals…
