Ab initio correlations between neutrinoless and two-neutrino double-beta decays in Ca
X. Lian, C. R. Ding, C. L. Bai +1
We develop a novel ab initio in-medium no-core configuration-interaction (IM-NCCI) framework for nuclear charge-exchange processes by combining the in-medium similarity renormaliza…

Deconfined Boundary Phase Transition of a Quantum Critical Heisenberg Model
Chengxiang Ding, Long Zhang
We investigate the boundary phases of a (2+1)-dimensional quantum critical Heisenberg model with a dangling spin chain. By introducing a multispin -term along the boundary, we d…

Continuously varying critical exponents in an exactly solvable long-range cluster XY mode
Tian-Cheng Yi, Chengxiang Ding, Maoxin Liu +2
We investigate a generalized antiferromagnetic cluster XY model in a transverse magnetic field, where long-range interactions decay algebraically with distance. This model can be e…
