U-spin sum rules for two-body decays of bottom baryons

open access: yesEuropean Physical Journal C: Particles and Fields
U-spin symmetry, which reflects the symmetry between the down-type d and s quarks, is a powerful tool for analyzing heavy hadron weak decays. Motivated by recent experimental achievements in the bottom baryon sector, we study the U-spin sum rules for ...

Non-Hermitian interacting quantum walks of correlated photons

open access: yesCommunications Physics
The non-Hermitian skin effect (NHSE), referring to the anomalous localization of eigenstates, has been widely discussed in single-particle systems. However, the interplay between the interacting NHSE and the quantum optical phenomena remains elusive ...

Quantum Error-Control Codes

open access: yes, 2020
The article surveys quantum error control, focusing on quantum stabilizer codes, stressing on the how to use classical codes to design good quantum codes. It is to appear as a book chapter in "A Concise Encyclopedia of Coding Theory," edited by C. Huffman, P. Sole and J-L Kim, to be published by CRC Press.

Exploring nontrivial topology at quantum criticality on a superconducting processor

open access: yesCommunications Physics
The discovery of nontrivial topology in quantum critical states has revised the classification of quantum phase transitions and opened a new direction for exploiting topological phases. However, the experimental investigation of gapless many-body systems

Enhancement of signal-to-noise ratio at a high-order exceptional point of coherent perfect absorption

open access: yesNature Communications
Exceptional points (EPs) in non-Hermitian systems offer a remarkably strong response to weak perturbations, but the nonorthogonal nature of the corresponding eigenvectors causes noise to diverge, hindering EPs practical application.

Atomistic origin of the reduced lattice thermal conductivity of silicon nanotubes

open access: yesAIP Advances, 2017
Understanding the effect of edge relaxation in nanotubes (NTs) with two kinds of surfaces has been of central importance in the exploration thermal transportation properties for their applications in thermoelectric energy harvesting and heat management ...

Thermodynamic topology of AdS black holes in rainbow gravity

open access: yesEuropean Physical Journal C: Particles and Fields
In this paper, we study the topology of four-dimensional AdS black holes with nonlinear sources in the framework of rainbow gravity. We apply the Duan’s $$\varphi $$ φ -mapping theory and the method of generalized free energy to study the topological ...
