Experimental Study of the Exciton Gas Liquid Transition in Coupled Quantum Wells
Subhradeep Misra, Michael Stern, Arjun Joshua +2
We study the exciton gas-liquid transition in GaAs/AlGaAs coupled quantum wells. Below a critical temperature, Tc=4.8K, and above a threshold laser power density the system undergo…
Characterization of individual layers in a bilayer electron system produced in a wide quantum well
S. I. Dorozhkin, A. A. Kapustin, I. B. Fedorov +3
Here we report on a transparent method to characterize individual layers in a double-layer electron system which forms in a wide quantum well and to determine their electron densit…
New ideas for tests of Lorentz invariance with atomic systems
Ravid Shaniv, Roee Ozeri, Marianna S. Safronova +4
We describe a broadly applicable experimental proposal to search for the violation of local Lorentz invariance (LLI) with atomic systems. The new scheme uses dynamic decoupling and…
Helical liquid in carbon nanotubes wrapped with DNA molecules
Yotam Perlitz, Karen Michaeli
The measured electric resistance of carbon nanotubes wrapped with DNA molecules depends strongly on the spin of the injected electrons. Motivated by these experiments, we study the…
The S66 noncovalent interactions benchmark reconsidered using explicitly correlated methods near the basis set limit
Manoj K. Kesharwani, Amir Karton, Nitai Sylvetsky +1
The S66 benchmark for noncovalent interactions has been re-evaluated using explicitly correlated methods with basis sets near the one-particle basis set limit. It is found that pos…
Two-level masers as heat-to-work converters
A. Ghosh, D. Gelbwaser-Klimovsky, W. Niedenzu +4
Heat engines, which cyclically transform heat into work, are ubiquitous in technology. Lasers and masers, which generate a coherent electromagnetic field, may be viewed as heat eng…
