Hard-core Hall tube in superconducting circuits
文献摘要：
The Hall tube as a minimum model to simulate the integer quantum Hall effect is essential for exploring topological physics,while it has not been constructed in the recent developing successfully experiments on superconducting circuits.In this work,we propose a feasible experiment scheme using three legs superconducting circuits with transmon qubits to realize a Hall tube.Then we first investigate its topological properties.Since the time-reversal,particle-hole,and chiral symmetries are all broken for the system,the Hall tube belongs to the A class of the Altland-Zirnbauer classification.We obtain the corresponding topological phase transition both numerically and analytically.Since the chirality is a key character of the quantum Hall effect,we secondly investigate the chiral physics in the Hall tube.We find the topological protected chiral edge currents and discuss its robustness.Finally,we give the possible experimental observations of the topological state and topological protected chiral edge currents.
