The Specification as Quality Gate: Three Hypotheses on AI-Assisted Code Review
Christo Zietsman
The dominant industry response to AI-generated code quality problems is to deploy AI reviewers. This paper argues that this response is structurally circular when executable specif…
Exceptional nexus in Bose-Einstein condensates with collective dissipation
Chenhao Wang, Nan Li, Jin Xie +6
In multistate non-Hermitian systems, higher-order exceptional points and exotic phenomena with no analogues in two-level systems arise. A paradigm is the exceptional nexus (EX), a…
Fractional Quantum Zeno Effect Emerging from Non-Hermitian Physics
Yue Sun, Tao Shi, Zhiyong Liu +4
Exploring non-Hermitian phenomenology is an exciting frontier of modern physics. However, the demonstration of a non-Hermitian phenomenon that is quantum in nature has remained elu…
Observation of interaction-induced mobility edge in a disordered atomic wire
Yunfei Wang, Jia-Hui Zhang, Yuqing Li +8
Mobility edge, a critical energy separating localized and extended excitations, is a key concept for understanding quantum localization. Aubry-André (AA) model, a paradigm for expl…
Topological atomic spinwave lattices by dissipative couplings
Dongdong Hao, Lin Wang, Xingda Lu +4
Recent experimental advance in creating dissipative couplings provides a new route for engineering exotic lattice systems and exploring topological dissipation. Using the spatial l…
Quantum superhet based on microwave-dressed Rydberg atoms
Mingyong Jing, Ying Hu, Jie Ma +4
The highly sensitive, phase- and frequency-resolved detection of microwave electric fields is of central importance for diverse fields ranging from astronomy, remote sensing, commu…
Fixed points and emergent topological phenomena in a parity-time-symmetric quantum quench
Xingze Qiu, Tian-Shu Deng, Ying Hu +2
We identify emergent topological phenomena such as dynamic Chern numbers and dynamic quantum phase transitions in quantum quenches of the non-Hermitian Su-Schrieffer-Heeger Hamilto…
