Elastic-viscoplastic constitutive model for overconsolidated unsaturated soils considering time effects and its verification

open access: yesYantu gongcheng xuebao, 2023
The time effects have a significant influence on the deformation characteristics of the overconsolidated unsaturated soils. Establishing an elastic-viscoplastic constitutive model for the overconsolidated unsaturated soils considering the time effects is

SU(2) non-Abelian gauge field theory in one dimension on digital quantum computers [PDF]

open access: yesPhysical Review D, 2019
An improved mapping of one-dimensional SU(2) non-Abelian gauge theory onto qubit degrees of freedom is presented. This new mapping allows for a reduced unphysical Hilbert space.

Two-Qubit Local Fisher Information Correlation beyond Entanglement in a Nonlinear Generalized Cavity with an Intrinsic Decoherence

open access: yesEntropy, 2021
In this paper, we study a Hamiltonian system constituted by two coupled two-level atoms (qubits) interacting with a nonlinear generalized cavity field. The nonclassical two-qubit correlation dynamics are investigated using Bures distance entanglement and

Emergent SU(2) Dynamics and Perfect Quantum Many-Body Scars. [PDF]

open access: yesPhysical Review Letters, 2018
Motivated by recent experimental observations of coherent many-body revivals in a constrained Rydberg atom chain, we construct a weak quasilocal deformation of the Rydberg-blockaded Hamiltonian, which makes the revivals virtually perfect.

A new SU(2) anomaly [PDF]

open access: yesJournal of Mathematics and Physics, 2018
A familiar anomaly affects SU(2) gauge theory in four dimensions: a theory with an odd number of fermion multiplets in the spin 1/2 representation of the gauge group, and more generally in representations of spin 2r+1/2, is inconsistent. We describe here

Phase Diagram of the Spin-1/2 Kitaev-Gamma Chain and Emergent SU(2) Symmetry. [PDF]

open access: yesPhysical Review Letters, 2019
We study the phase diagram of a one-dimensional version of the Kitaev spin-1/2 model with an extra "Γ term," using analytical, density matrix renormalization group and exact diagonalization methods. Two intriguing phases are found.

Outcomes and complications of severe acute postpartum hemorrhage treated with or without transarterial embolization in a single tertiary referral center: A 20-year experience

open access: yesTaiwanese Journal of Obstetrics & Gynecology, 2021
Objective: PPH is usually unpredictable; and such fast, urgent and sudden massive life-threating hemorrhage. This study is to assess the efficacy of transarterial embolization (TAE) in treating severe PPH in a single institution over a period of 20 years.
