Emergence of the Scrooge Ensemble in the Sachdev-Ye-Kitaev Model
Zeyu Liu, Pengfei Zhang
The probabilistic nature of quantum measurement provides a direct window into the structure and complexity of many-body wave functions. When only part of a system is measured, the…
Curvature-driven revival of charge density waves in non-Euclidean space
Zhipeng Song, Zeyu Liu, Junde Liu +12
Strongly correlated quantum states, such as charge density waves (CDWs), are exquisitely sensitive to Fermi surface topology and lattice symmetry, and are typically quenched by hea…
Bridging Krylov Complexity and Universal Analog Quantum Simulator
Shuo Zhang, Yuzhi Tong, Pengfei Zhang +1
Quantum simulation of complex many-body systems beyond classical computational capabilities provides a promising route toward understanding novel quantum phases and their transitio…
Distinguishing Coherent and Incoherent Errors in Multi-Round Time-Reversed Dynamics via Scramblons
Zeyu Liu, Pengfei Zhang
Despite the rapid development of quantum science and technology, errors are inevitable and play a crucial role in quantum simulation and quantum computation. In quantum chaotic sys…
Rabi Oscillations of Strongly Driven Bose Polarons
Zeyu Liu, Pengfei Zhang
Understanding the dynamical behavior of quasiparticles is essential for uncovering novel quantum many-body phenomena. Among these phenomena, the polaron in ultracold atomic gases h…
Scrambling Enabled Entropy Accumulation in Open Quantum Systems
Yuke Zhang, Zeyu Liu, Shuo Zhang +2
In closed quantum many-body systems, initially localized information spreads throughout the system and becomes highly complex. This phenomenon, known as information scrambling, is…
