Physical Predictions in Closed Quantum Gravity

Kavli Affiliate: Yasunori Nomura | Summary:Recent developments in gravitational path integrals indicate that the nonperturbative physical Hilbert space of a closed universe is one-dimensional within each superselection sector. This raises a basic puzzle: how can a unique quantum-gravity state give rise to semiclassical physics, measurement outcomes, and classical probabilities? In this paper, we develop a […]

TIC-65910228 b / NGTS-38 b, a 180 day transiting warm super-Jupiter

Kavli Affiliate: Avi Shporer | Summary:We present the discovery of TIC-65910228 b / NGTS-38 b, a giant exoplanet with a radius of $1.081pm0.047$ R$_textJ$ and a mass of $4.78_-0.37^+0.39$ M$_textJ$ on a long-period ($180.52797pm0.00036$ day), moderately eccentric ($e=0.3086pm0.010$) orbit transiting a bright (V=$10.230pm0.020$ mag) metal rich ([Fe/H]=$0.33pm0.09$, ‘dex’) F6V-F7V type host star. The planet was […]

Dependence of the Mn sticking coefficient on Ga-rich, N-rich, and Ga/N-flux-free conditions in GaN grown by plasma-assisted molecular beam epitaxy

Kavli Affiliate: Grace Xing | Summary:This brief report examines the influence of Ga/N flux conditions on Mn incorporation in GaN. Mn-doped GaN layers were grown at 680$^circ$C by molecular beam epitaxy on a Ga-polar GaN(0001) template substrate under Ga-rich, N-rich, and no-flux conditions (i.e., Mn $δ$ doping). Mn incorporation was highest under N-rich condition, lowest […]

What and where manifolds emerge and align with perception in deep neural network models of sound localization

Kavli Affiliate: Xiaoqin Wang | Authors: Chenggang Chen, Zhiyu Yang and Xiaoqin Wang | Summary: Whether the auditory cortex has parallel pathways for sound identification (“what”) and localization (“where”), and whether it contains a map of auditory space, is debated. Here, we examined the low-dimensional structure (manifold) of “what” and “where” representations in deep neural […]
