Design, Testing, and Commissioning of the Sun Yat-sen University (SYSU) 80 cm Infrared Telescope
Zhong-Nan Dong, Bin Ma, Chun Chen +23
The Sun Yat-sen University (SYSU) 80 cm telescope is a new generation near-infrared (NIR) facility in China dedicated to time-domain astronomy, while also serving as a testbed for…
-type Lieb-Schultz-Mattis anomalies, deconfined quantum critical points, and non-invertible symmetry breaking
Hao-Ran Zhang, Hanlin Lin, Shuo Yang +1
We study deconfined quantum critical points (DQCP) associated with Lieb-Schultz-Mattis (LSM) anomalies in one-dimensional spin chains. Our starting point is a structural characteri…
A Poincaré-covariant study of strange quark stars
Hao-Ran Zhang, Bo-Lin Li, Zhu-Fang Cui
We investigate the properties of dense quark matter and strange quark stars within a nonperturbative, Poincaré-covariant framework. Employing a symmetry-preserving vector$\,\otime…
Shadow of topologically charged rotating braneworld black hole
Hao-Ran Zhang, Peng-Zhang He, Lei-Shao +2
In this paper, we discuss optical properties of the topologically charged rotating black hole. We study the horizon, the photon region, the shadow of the black hole and other obser…
Boundary anomaly detection in two-dimensional subsystem symmetry-protected topological phases
Ke Ding, Hao-Ran Zhang, Bai-Ting Liu +1
We generalize the topological response theory to detect the boundary anomalies of linear subsystem symmetries. This approach allows us to distinguish different subsystem symmetry-p…
Shadow cast by a rotating and nonlinear magnetic-charged black hole in perfect fluid dark matter
Tian-Chi Ma, He-Xu Zhang, Peng-Zhang He +3
We derived an exact solution of the spherically symmetric Hayward black hole surrounded by perfect fluid dark matter (PFDM). By applying the Newman-Janis algorithm, we generalized…
Crossover or First-Order: Impacts of Regularization
Xin-Peng Li, Hao-Ran Zhang, Zhu-Fang Cui +1
The equation of state of hot, dense nuclear matter plays a fundamental role in many areas. However, owing to the nonperturbative nature of strong interactions, a reliable treatment…
Preparation of quasi-two-dimensional Bose mixture of ultracold Na and Rb atoms
Ji-Kai Liao, Hao-Ran Zhang, Xiao-Rong Yu +5
Quantum gases confined in reduced dimensions have enabled the observation of many exotic quantum phenomena. While existing experiments primarily focus on homonuclear systems, we re…
Intrinsically Interacting Higher-Order Topological Superconductors
Hao-Ran Zhang, Jian-Hao Zhang, Zheng-Cheng Gu +2
We propose a minimal interacting lattice model for two-dimensional class- higher-order topological superconductors with no free-fermion counterpart. A Lieb-Schultz-Mattis-type c…
Quantifying Quantum Computational Advantage on a Processor of Ultracold Atoms
Yong-Guang Zheng, Ying-Chao Shen, Wei-Yong Zhang +15
Nonequilibrium dynamics of quantum many-body systems is challenging for classical computing, providing opportunities for demonstrating practical quantum computational advantage wit…
Shadows of rotating Hayward-de Sitter black holes with astrometric observables
Peng-Zhang He, Qi-Qi Fan, Hao-Ran Zhang +1
Motivated by recent work on rotating black hole shadow [Phys. Rev. D101, 084029 (2020)], we investigate the shadow behaviors of rotating Hayward-de Sitter black hole for static obs…
Locally Purified Density Operators for Symmetry-Protected Topological Phases in Mixed States
Yuchen Guo, Jian-Hao Zhang, Hao-Ran Zhang +2
We propose a tensor network approach known as the locally purified density operator (LPDO) to investigate the classification and characterization of symmetry-protected topological…
The cosmological constant from space-time discreteness
Qi-Qi Fan, Cong Li, Hao-Ran Zhang +2
We regard the background of space-time as a physical system composed of discrete volume elements at the Planck scale and get the internal energy of space-time by Debye model. A tem…
