A New High-Intensity Source for Ultracold Neutrons

K. Abe, S. Ahmed, B. Algohi +78

The TRIUMF UltraCold Advanced Neutron (TUCAN) collaboration has completed a new superthermal source for ultracold neutrons (UCNs) at TRIUMF. It uses neutrons from a spallation targ…

Background Fields Meet the Heat Kernel: Gauge Invariance and RGEs without diagrams

Debanjan Balui, Joydeep Chakrabortty, Christoph Englert +2

We introduce a new method that exploits the combination of the Heat Kernel (HK) and Background Field Method to compute gauge-invariant and gauge parameter-independent quantities su…

Higher-dimensional operators and Polyakov loop in hot Scalar QED from the heat kernel

Siddhartha Bandyopadhyay, Joydeep Chakrabortty, Debmalya Dey +2

Using the finite-temperature heat kernel method, we compute the gauge-invariant effective Lagrangian up to dimension-six for massive hot scalar QED. We propose two complementary me…

Initial results of the TRIUMF ultracold advanced neutron source

B. Algohi, D. Anthony, L. Barrón-Palos +83

We report the first results on ultracold neutron production from a new spallation-driven superfluid He (He-II) source at TRIUMF, which is being prepared for a new, precise meas…

Magic Secret Sharing: Threshold Control of Quantum Computational Power via GHZ Entanglement

Soumyojyoti Dutta, Tushar

We introduce Magic Secret Sharing (MSS), a quantum cryptographic primitive in which the secret is the computational capability of a quantum state rather than its classical descript…

Ultracold Neutron Guide-Coating Facility at U.Winnipeg

T. Hepworth, A. Zahra, B. Algohi +72

We report the construction and commissioning of a new ultracold neutron (UCN) guide-coating facility at the University of Winnipeg. The facility employs pulsed laser deposition (PL…
