Experimental observation of the Yang-Lee quantum criticality in open systems
Huixia Gao, Kunkun Wang, Lei Xiao +6
The Yang-Lee edge singularity was originally studied from the standpoint of mathematical foundations of phase transitions, and its physical demonstration has been of active interes…
Electronic properties of nickelate superconductor R3Ni2O7 with oxygen vacancies
Xuelei Sui, Xiangru Han, Xiaojun Chen +3
The discovery of superconductivity in La3Ni2O7 has attracted significant research interest in the field of nickelate superconductors. Despite extensive studies on pristine La3Ni2O7…
Understanding spin textures in PT-broken systems through universal symmetry-constrained rules
Wei Tan, Jianfeng Wang, Yang Li +1
The current understanding of spin-polarization phenomena in crystals relies heavily on the development of specific k.p Hamiltonians. A more fundamental and symmetry-driven understa…
A composite ansatz for the calculation of dynamical structure factor
Yupei Zhang, Chongjie Mo, Ping Zhang +1
We propose an ansatz without adjustable parameters for the calculation of dynamical structure factor. The ansatz combines quasi-particle Green's function, especially the contributi…
Effects of dilution in a 2D topological magnon insulator
Miguel S. Oliveira, T. V. C. Antão, Eduardo V. Castro +1
We study the effect of diluting a two-dimensional ferromagnetic insulator hosting a topological phase in the clean limit. By considering the ferromagnetic Heisenberg model in the h…
Phase transitions in the Haldane-Hubbard model
Wan-Xiu He, Rubem Mondaini, Hong-Gang Luo +2
The Haldane-Hubbard model is a prime example of the combined effects of band topology and electronic interaction. We revisit its spinful phase diagram at half-filling as a consensu…

Superconductivity in single-layer graphene has attracted considerable interest. Here, using the determinant quantum Monte Carlo method, we study transitions of superconductivity an…
Two-mode correlated multiphoton bundle emission
Yi Wang, Fen Zou, Jie-Qiao Liao
The preparation of correlated multiphoton sources is an important research topic in quantum optics and quantum information science. Here, two-mode correlated multiphoton bundle emi…
Sampling reduced density matrix to extract fine levels of entanglement spectrum and restore entanglement Hamiltonian
Bin-Bin Mao, Yi-Ming Ding, Zhe Wang +2
The reduced density matrix (RDM) plays a key role in quantum entanglement and measurement, as it allows the extraction of almost all physical quantities related to the reduced degr…
Fractal Quasicondensation in One Dimension
Flavio Riche, Miguel Gonçalves, Bruno Amorim +2
We unveil a novel mechanism for quasicondensation of hard-core bosons in the presence of quasiperiodicity-induced multifractal single-particle states. The new critical state, here…
Extreme Spontaneous Deformations of Active Crystals
Xia-qing Shi, Fu Cheng, Hugues Chaté
We demonstrate that two-dimensional crystals made of active particles can experience extremely large spontaneous deformations without melting. Using particles mostly interacting vi…
