Accurate Point Defect Energy Levels from Non-Empirical Screened Range-Separated Hybrid Functionals: the Case of Native Vacancies in ZnO

Posted by dbos Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Sijia Ke, Stephen E. Gant, Leeor Kronik, Jeffrey B. Neaton, | Summary: We use density functional theory (DFT) with non-empirically tuned screened range-separated hybrid (SRSH) functionals to calculate the electronic properties of native zinc and oxygen vacancy point defects in ZnO, and we predict their defect […]

Probing Majorana localization of a phase-controlled three-site Kitaev chain with an additional quantum dot

Posted by klaurent Delft

Kavli Affiliate: L. P. Kouwenhoven| First 5 Authors: Alberto Bordin, Alberto Bordin, , , | Summary:Few-site implementations of the Kitaev chain offer a minimal platform to study the emergence and stability of Majorana bound states. Here, we realize two- and three-site chains in semiconducting quantum dots coupled via superconductors, and tune them to the sweet […]

Detecting Intermediate-mass Black Holes Using Quasar Microlensing

Posted by dbos Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Zihao Wu, Luis C. Ho, , , | Summary: Recent studies suggest that numerous intermediate-mass black holes (IMBHs) may wander undetected across the Universe, emitting little radiation. These IMBHs largely preserve their birth masses, offering critical insights into the formation of heavy black hole seeds and […]

Q-balls Under Spontaneously Broken U(1) Symmetry

Posted by klaurent Tokyo

Kavli Affiliate: Masahiro Kawasaki | Summary:We study the evolution of Q-balls under a spontaneously broken global $U(1)$ symmetry. Q-balls are stabilized by the conservation of $U(1)$ charge, but when the symmetry is spontaneously broken, the resulting Nambu-Goldstone (NG) boson can carry charge away from the Q-ball, potentially leading to charge leakage. To study this process […]

Hippocampus facilitates reinforcement learning under partial observability

Posted by dbos Columbia

Kavli Affiliate: Rui Costa | Authors: Dabal Pedamonti, Samia Mohinta, Martin Dimitrov, Hugo Malagon-Vina, Stephane Ciocchi and Rui Ponte Costa | Summary: Mastering navigation in environments with limited visibility is crucial for survival. Although the hippocam-pus has been associated with goal-oriented navigation, its role in real-world behaviour remains unclear. To investigate this, we combined deep […]

Cosmological Evolution of Fast Radio Bursts and The Star Formation Rate

Posted by klaurent Stanford

Kavli Affiliate: Vahe Petrosian | Summary:We investigate the cosmological evolution of the luminosity and redshift of FRBs. As is the case for all extragalactic sources, we are dealing with data that are truncated by observational selection effects, the most important being the flux limit, which introduces the so-called Eddington-Malmquist bias. In addition, for FRBs, there […]

Sensitivity of BEACON to Ultra-High Energy Diffuse and Transient Neutrinos

Posted by klaurent Chicago

Kavli Affiliate: Eric Oberla | Summary:Ultra-high energy neutrinos ($E>10^17$ eV) can provide insight into the most powerful accelerators in the universe, however their flux is extremely low. The Beamforming Elevated Array for COsmic Neutrinos (BEACON) is a detector concept which efficiently achieves sensitivity to this flux by employing phased radio arrays on mountains, which search […]
