Emergent Rokhsar-Kivelson point in realistic quantum Ising models
Zheng Zhou, Zheng Yan, Changle Liu +2
We show that the Rokhsar-Kivelson (RK) point in quantum dimer models (QDM) can emerge in realistic quantum Ising spin systems. Specifically, we investigate the -- tr…
Fractal Quantum Phase Transitions: Critical Phenomena Beyond Renormalization
Zheng Zhou, Xue-Feng Zhang, Frank Pollmann +1
We identify a quantum critical point with fractal symmetry whose effective theory eludes the renormalization group framework. We consider the Newman-Moore model with three-body int…
Generating and detecting entangled cat states in dissipatively coupled degenerate optical parametric oscillators
Zheng-Yang Zhou, Clemens Gneiting, J. Q. You +1
Non-Gaussian continuous variable states play a central role both in the foundations of quantum theory and for emergent quantum technologies. In particular, "cat states", i.e., two-…
Stability and collisions of quantum droplets in PT -symmetric dual-core couplers
Zheng Zhou, Bo Zhu, Haibin Wang +1
We study the effect of the interplay between parity-time () symmetry and optical lattice (OL) potential on dynamics of quantum droplets (QDs) forming in a binary boso…
Floquet-surface bound states in the continuum in a resonantly driven 1D tilted defect-free lattice
Bo Zhu, Yongguan Ke, Wenjie Liu +2
We study the Floquet-surface bound states embedded in the continuum (BICs) and bound states out the continuum (BOCs)in a resonantly driven 1D tilted defect-free lattice. In contras…
Widely existing mixed phase structure of quantum dimer model on square lattice
Zheng Yan, Zheng Zhou, Olav F. Syljuåsen +4
Since constraints hinder the application of numerical algorithms, phase diagrams of quantum dimer models are still controversial, even on the square lattice. The core controversy i…
