Temporal Dynamical Quantum Phase Transition in Dicke Model with Trapped Ions
Ji Bian, Wei Wu, Zihan Xie +8
Temporal non-analyticities in the rate function of the Loschmidt echo manifests a class of dynamical quantum phase transitions (DQPTs) that has emerged as a powerful framework for…
Non-Abelian Aharonov-Bohm Caging in Synthetic Dimensions with a Trapped Ion
Wanchao Yao, Sai Li, Zhiyuan Liu +7
Aharonov-Bohm (AB) caging is a complete localization phenomenon in two-dimensional lattices due to destructive interference induced by the background gauge fields. However, current…
Quantum Simulation of Oscillatory Unruh Effect with Superposed Trajectories
Xu Cheng, Yue Li, Zehua Tian +3
The Unruh effect predicts an astonishing phenomenon that an accelerated detector would detect counts despite being in a quantum field vacuum in the rest frame. Since the required d…
A15 Phase Ta3Sb Thin Films: Direct Synthesis, Charge Transport and Spin-Orbit Torque
J. S. Jiang, Qianheng Du, Yi Li +9
Ta3Sb is one of the A15 compounds that have been predicted to have giant spin Hall conductivities due to the gapped Dirac-like band crossings in their electronic structures. We use…
High-fidelity two-qubit quantum logic gates in a trapped-ion chain using axial motional modes
Xingyu Zhao, Ji Bian, Yi Li +3
Trapped-ion systems are one of the leading platforms for quantum information processing, where a key challenge is to scale up system size while maintaining high-fidelity two-qubit…
Experimental Proposal on Non-Abelian Aharonov-Bohm Caging Effect with a Single Trapped Ion
Zhiyuan Liu, Wanchao Yao, Sai Li +4
In the lattice system, when the synthetic flux reaches a phase along a closed loop under the synthetic gauge field, destructive interference occurs and gives rise to the local…
