Detecting Sterile Neutrino Dark Matter at MeV Gamma-Ray Observatories

Kavli Affiliate: Shigeki Matsumoto | Summary:We explore the indirect detection of sterile neutrino dark matter within the gauged $U(1)_B-L$ extension of the Standard Model, in which three right-handed neutrinos account for neutrino masses, the baryon asymmetry, and dark matter. Focusing on the MeV mass range, we investigate two decay channels: the radiative decay $N to […]

Emergent gauge flux in mixed QED$_3$ with flavor chemical potential: application to magnetized U(1) Dirac spin liquids

Kavli Affiliate: Leon Balents | Summary:We design a lattice model of a "mixed" U(1) gauge field coupled to fermions with a flavor chemical potential and solve it with large-scale determinant quantum Monte Carlo simulations, For zero flavor chemical potential, the model realizes three-dimensional quantum electrodynamics (QED$_3$) which has been argued to describe the ground state […]

Oscillations and parity violation in gravitational wave background from extra tensor modes

Kavli Affiliate: Misao Sasaki | Summary:Spectator fields which provide additional tensor degrees of freedom, on top of the standard metric tensor perturbations, can produce significant amounts of gravitational waves (GWs). Employing the effective field theory approach for spin-2 fields, we identify a characteristic prediction of this class of scenarios: whenever the spin-2 sector undergoes a […]

Deriving the von Neumann equation from the Majorana-Bloch equation for arbitrary spin in any state

Kavli Affiliate: Lihong V. Wang| First 5 Authors: Lihong V. Wang, Lihong V. Wang, , , | Summary:After publishing the derivation from the classical Bloch equation to the quantum von Neumann equation to the Schrdinger-Pauli equation for spin-$tfrac12$, we proposed renaming the Bloch equation to the Majorana-Bloch equation because Majorana’s work predated Bloch’s in the […]

Spin-orbit-enabled realization of arbitrary two-qubit gates on moving spins

Kavli Affiliate: Lieven Vandersypen | Summary:Shuttling spin qubits in systems with large spin-orbit interaction (SOI) can cause errors during motion. However, in this work, we demonstrate that SOI can be harnessed to implement an arbitrary high-fidelity two-qubit (2Q) gate. We consider two spin qubits defined in a semiconductor double quantum dot that are smoothly moved […]

ReconDreamer-RL: Enhancing Reinforcement Learning via Diffusion-based Scene Reconstruction

Kavli Affiliate: Zheng Zhu | First 5 Authors: Chaojun Ni, Chaojun Ni, , , | Summary: Reinforcement learning for training end-to-end autonomous driving models in closed-loop simulations is gaining growing attention. However, most simulation environments differ significantly from real-world conditions, creating a substantial simulation-to-reality (sim2real) gap. To bridge this gap, some approaches utilize scene reconstruction […]
