Scientists stunned by record-breaking, watermelon-shaped nucleus
For the first time in more than thirty years, the heaviest nucleus decaying via proton emission has been measured. The previous similar breakthrough was achieved in 1996.
The radioactive decay of atomic nuclei has been one of the keystones of…

Multi video stream collaborative adaptive offloading scheme based on equilibrium game theory
Game theory is a mathematical method for selecting a strategy that maximizes the profits of each agent in the presence of multiple parties.27 In a game, the insteractions between players are mutual, and each player’s decision will have an…

Spin-triplet pair density wave superconductors
Two pairing channels
The two attraction terms in Eq. (2) can be written as
$${\hat{H}}_{I} = -\frac{{V}_{1}}{{N}_{c}}{\sum}_{k,{k}^{\prime },q,\sigma }\sin k\sin {k}^{\prime }{c}_{k+\frac{q}{2}\sigma }^{{{\dagger}} }{c}_{-k+\frac{q}{2}\sigma…

Generalized number-phase lattice encoding of a bosonic mode for quantum error correction
Generalized number-phase encoding
Inspired by the construction of GKP codes in the quadrature phase space, we introduce generalized displacement operators in the NP space. Consider a bosonic mode described by the annihilation and creation…

Low-loss superconducting resonators fabricated from tantalum films grown at room temperature
Resonator design and measurements
In order to assess the influence of the sputtering method on the performance of superconducting circuits patterned into the Ta films, λ/4 CPW resonators in the 4.5–6.5 GHz frequency range were fabricated from…
