Trotter errors in digital adiabatic quantum simulation of quantum lattice gauge theory
Xiaopeng Cui, Yu Shi
Trotter decomposition is the basis of the digital quantum simulation. Asymmetric and symmetric decompositions are used in our GPU demonstration of the digital adiabatic quantum sim…
Entangled baryons: violation of Inequalities based on local realism assuming dependence of decays on hidden variables
Yu Shi, Ji-Chong Yang
Bell inequalities are consequences of local realism while violated by quantum mechanics. In particle physics, entangled high energy particles can be produced from a common source,…
Circuit-based digital adiabatic quantum simulation and pseudoquantum simulation as new approaches to lattice gauge theory
Xiaopeng Cui, Yu Shi, Ji-Chong Yang
Gauge theory is the framework of the Standard Model of particle physics and is also important in condensed matter physics. As its major non-perturbative approach, lattice gauge the…
Generation of magnetic skyrmions through pinning effect
Ji-Chong Yang, Qing-Qing Mao, Yu Shi
Based on analytical estimation and lattice simulation, a proposal is made that magnetic skyrmions can be generated through the pinning effect in 2D chiral magnetic materials, in ab…
Shape of a skyrmion
Ji-Chong Yang, Qing-Qing Mao, Yu Shi
We propose a method of determining the shape of a two-dimensional magnetic skyrmion, which can be parameterized as the position dependence of the orientation of the local magnetic…
Decoherence and disentanglement of qubits detecting scalar fields in an expanded universe
Yujie Li, Yue Dai, Yu Shi
We consider Unruh-Wald qubit detector model adopted for the far future region of an exactly solvable 1+1 dimensional scalar field theory in a Robertson-Walker expanding spacetime.…
