Quantum criticality in sub-Ohmic systems with three competing terms: beyond conventional spin-boson physics
Nengji Zhou, Yulong Shen, Zhe Sun
Quantum phase transitions (QPTs) in the spin-boson model with/without the rotating-wave approximation (RWA) are systematically investigated through variational calculations using a…
Dielectric response in twisted MoS2 bilayer facilitated by spin-orbit coupling effect
Yu-Hao Shen, Jun-Ding Zheng, Wen-Yi Tong +3
Twisted van der Waals bilayers offer ideal two-dimensional (2D) platforms for exploring the intricate interplay between the spin and charge degrees of freedom of electrons. By inve…
Quantum valley Hall states in low-buckled counterparts of graphene bilayer
Yu-Hao Shen, Jun-Ding Zheng, Wen-Yi Tong +3
With low-buckled structure for each layer in graphene bilayer system, there breaks inversion symmetry (P-symmetry) for one stacking when both A and B sublattices in top layer are a…
Electrical reversal of the sign for magnon thermal Hall coefficient in a van der Waals bilayer antiferromagnet
Yu-Hao Shen, Yiqun Liu, Min Luo
With spin-layer locking, the manipulation of spin degree of freedom via perpendicular electric field can be realized in a typical antiferromagnetically coupled bilayer. In analogy…
