A Modified Stern-Gerlach Experiment Using a Quantum Two-State Magnetic Field

, 2017
The Stern-Gerlach experiment has played an important role in our understanding of quantum behavior. We propose and analyze a modified version of this experiment where the magnetic field of the detector is in a quantum superposition, which may be ...

Warming Enhances CO₂ Flux from Saline–Alkali Soils by Intensifying Moisture–Temperature Interactions in the Critical Zone

Land
Saline–alkali soils in arid regions are increasingly recognized as critical yet underrepresented components of the global carbon cycle. However, their CO2 flux dynamics under warming remain poorly understood. In this study, we conducted controlled growth-

Photon splitting in atomic fields

, 2001
Photon splitting due to vacuum polarization in the electric field of an atom is considered. We survey different theoretical approaches to the description of this nonlinear QED process and several attempts of its experimental observation.

Punishment, reward, and cooperation in a framed field experiment [PDF]

We report a framed field experiment, in which we study the effectiveness of punishment and reward in sustaining cooperation in a social dilemma. Punishments tend to be directed at non-cooperators and rewards are assigned by those who are relatively ...

Farmers’ Adaptation to Climate Change: A Framed Field Experiment [PDF]

The risk of losing income and productive means due to adverse weather can differ significantly among farmers sharing a productive landscape and is, of course, hard to estimate or even “guesstimate” empirically.

Variation characteristics and influencing mechanisms of CO2 flux from grassland ecosystem in the Central Tianshan Mountains, China

Ecological Indicators
The intensification of carbon dioxide (CO2) fluxes in grassland ecosystems due to global climate change makes the achievement of carbon neutrality goals more challenging, particularly in arid regions with sensitive climates and fragile ecological ...

Blood Donations and Incentives: Evidence from a Field Experiment [PDF]

There is a longstanding concern that material incentives might undermine prosocial motivation, leading to a decrease in blood donations rather than an increase.
