A CLOSELY RESPONDING, VERSATILE WAVE TUNNEL

Millimeter-Wave Propagation Measurement Through a Dust Tunnel

Responding to Covid-19 — A Once-in-a-Century Pandemic?

SARS-CoV-2 is a highly transmissible respiratory virus causing COVID-19, a disease that has become pandemic. It is the biggest public health concern of this century. The sudden emergence of the novel SARS-CoV-2 has rapidly evolved into a pandemic that posed a serious threat to global health and economy Throughout the COVID-19 pandemic, solving immediate problems and preventing problems are two ...

Versatile optical access to the tunnel gap in a low-temperature scanning tunneling microscope.

We developed a setup that provides three independent optical access paths to the tunnel junction of an ultrahigh vacuum low temperature (4.2 K) scanning tunneling microscope (STM). Each path can be individually chosen to couple light in or out, or to image the tunnel junction. The design comprises in situ adjustable aspheric lenses to allow tip exchange. The heat input into the STM is negligibl...

Airy–Bessel wave packets as versatile linear light bullets

The generation of spatiotemporal optical wave packets that are impervious to both dispersion and diffraction has been a fascinating challenge1. Despite intense research activity, such localized waves, referred to as light bullets, have remained elusive. In nonlinear propagation, three-dimensional light bullets tend to disintegrate as a result of inherent instabilities2,3. Threedimensional wave ...

Tunnel Resonance of Electron Wave and Force of Fluctuation

We propose that cool fusion is fluctuation of the resonance which happens to the electron wave. When electricity is discharged, a special crystal is made from free particles by the tunnel phenomenon of the electron wave. If free particles line up in the arrangement of the crystal, and the particle shifts, the line makes a wave. When alignment fluctuates, phase transition occurs in crystal. Ther...
