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…
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…
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…
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…
