Shubnikov-de Haas oscillations in coherently strained AlN/GaN/AlN quantum wells on bulk AlN substrates

Posted by dbos Cornell

Kavli Affiliate: Grace Xing | First 5 Authors: Yu-Hsin Chen, Jimy Encomendero, Huili Grace Xing, Debdeep Jena, | Summary: We report the observation of Shubnikov-de Haas (SdH) oscillations in coherently strained, low-dislocation AlN/GaN/AlN quantum wells (QWs), including both undoped and $delta$-doped structures. SdH measurements reveal a single subband occupation in the undoped GaN QW and […]

Shedding light on the star formation rate-halo accretion rate connection and halo quenching mechanism via DECODE, the Discrete statistical sEmi-empiriCal mODEl

Posted by dbos Peking

Kavli Affiliate: Yingjie Peng | First 5 Authors: Hao Fu, Lumen Boco, Francesco Shankar, Andrea Lapi, Mohammadreza Ayromlou | Summary: Aims: The relative roles of the physical mechanisms involved in quenching galaxy star formation are still unclear. We tackle this fundamental problem with our cosmological semi-empirical model DECODE (Discrete statistical sEmi-empiriCal mODEl), designed to predict […]

Evolving dark energy models: Current and forecast constraints

Posted by dbos Chicago

Kavli Affiliate: Joshua A. Frieman | First 5 Authors: Anowar J. Shajib, Joshua A. Frieman, , , | Summary: Recent results from Type Ia supernovae (SNe Ia) and baryon acoustic oscillations (BAO), in combination with cosmic microwave background (CMB) measurements, have focused renewed attention on dark energy models with a time-varying equation-of-state parameter, $w(z)$. In […]

Nonrenormalization Theorem for ${cal N}=(4,4)$ Interface Entropy

Posted by dbos Tokyo

Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Andreas Karch, Hirosi Ooguri, Mianqi Wang, , | Summary: We derive a formula for the half-BPS interface entropy between any pair of ${cal N}=(4,4)$ theories on the same conformal manifold. This generalizes the diastasis formula derived in arXiv:1311.2202 for ${cal N}=(2,2)$ theories, which is restricted to the […]
