Quantum point contacts as heat engines [PDF]
Physica E 74, 447 (2015), 2015 The efficiency of macroscopic heat engines is restricted by the second law of thermodynamics. They can reach at most the efficiency of a Carnot engine. In contrast, heat currents in mesoscopic heat engines show fluctuations. Thus, there is a small probability that a mesoscopic heat engine exceeds Carnot's maximum value during a short measurement time ...

Five‐year evaluation of linear accelerator‐based SRS platform isocentricity
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Linear accelerator (LINAC)‐based stereotactic radiosurgery (SRS) has become a mainstay in the management of intracranial tumors. However, the high fractional doses and sharp gradients used in SRS place heavy demands on geometric accuracy.

Topological Crystalline Insulator Nanomembrane with Strain-Tunable Band Gap [PDF]
, 2014 The ability to fine-tune band gap and band inversion in topological materials is highly desirable for the development of novel functional devices. Here we propose that the electronic properties of a free-standing nanomembrane of topological crystalline ...
