Quantum entanglement in nuclear Cooper-pair tunneling with γ rays
(American Physical Society, 2021)
While Josephson-like junctions, transiently established in heavy-ion collisions (τcoll ≈ 10−21 s) between superfluid nuclei—and through which Cooper-pair tunneling (Q-value Q2n) proceeds mainly in terms of successive transfer ...

Excited-state Quantum Phase Transitions in the Anharmonic Lipkin-Meshkov-Glick Model: Dynamical Aspects
(American Physical Society, 2023)
The standard Lipkin-Meshkov-Glick (LMG) model undergoes a second-order ground-state quantum phase transition (QPT) and an excited-state quantum phase transition (ESQPT). The inclusion of an anharmonic term in the LMG ...

Digital-analog quantum computation with arbitrary two-body Hamiltonians
(American Physical Society, 2024-03-14)
Digital-analog quantum computing is a computational paradigm which employs an analog Hamiltonian resource together with single-qubit gates to reach universality. Here, we design a new scheme which employs an arbitrary ...
