Phase diagram of the extended chequerboard model
Jiayou Yin, Lu Liu
The chequerboard model was proposed to describe the direct phase transition from the antiferromagnetic (AFM) state to the plaquette-sin glet (PS) solid state observed in SrCu…
Coplanar order induced by emergent frustration
Zehui Deng, Lu Liu, Wenan Guo +1
Traditional frustration arises from the conflict between the spin alignments due to the geometry or the nature of the interactions. Here, we demonstrate a novel form of frustration…
Diagnosing Symmetry and First-Order Transition in the Model via Entanglement Entropy
Zehui Deng, Lu Liu, Wenan Guo +1
We study the scaling behavior of the Rényi entanglement entropy with smooth boundaries at the phase transition point of the two-dimensional model. Using the recently develo…
Improved scaling of the entanglement entropy of quantum antiferromagnetic Heisenberg systems
Zehui Deng, Lu Liu, Wenan Guo +1
In this paper, we derive corrections to the subleading logarithmic term of the entanglement entropy in systems with spontaneous broken continuous symmetry. Using quantum Monte Carl…
Proximate deconfined quantum critical point in SrCu2(BO3)2
Yi Cui, Lu Liu, Huihang Lin +10
The deconfined quantum critical point (DQCP) represents a paradigm shift in quantum matter studies, presenting a "beyond Landau" scenario for order--order transitions. Its experime…
Experimental investigation of quantum uncertainty relations with classical shadows
Lu Liu, Ting Zhang, Xiao Yuan +1
The quantum component in uncertainty relation can be naturally characterized by the quantum coherence of a quantum state, which is of paramount importance in quantum information sc…
