Waveform-Controlled Terahertz Radiation the Air Filament Few-Cycle Laser Pulses Optics
2012/4/20
Waveform-controlled Terahertz (THz) radiation is of great importance due to its potential application in THz sensing and coherent control of quantum systems. We demonstrated a novel scheme to generate...
Hyperbolic metamaterial interfaces: Hawking radiation from Rindler horizons and the "end of time"
Hyperbolic metamaterial interfaces Hawking radiation Rindler horizons
2011/8/5
Abstract: Extraordinary rays in a hyperbolic metamaterial behave as particle world lines in a three dimensional (2+1) Minkowski spacetime. We analyze electromagnetic field behavior at the boundaries o...

Hawking Radiation and Entropy Horizon Degrees of Freedom
2010/12/20
We study the thermodynamic properties of horizons using the dynamical description of the grav-
itational degrees of freedom at a horizon given in [4]. We use the action of the horizon degrees of free...
Gamma spectroscopic measurements using the PID350 pixelated CdTe radiation detector
Gamma spectroscopic measurements the PID350 pixelated CdTe radiation detector
2010/11/16
Spectroscopic measurements are presented using the PID350 pixelated gamma radiation detectors. A high-speed data acquisition system has been developed in order to reduce the data loss during the data...
An accelerated particle sees the Minkowski vacuum as thermally excited, and the particle
moves stochastically due to an interaction with the thermal bath. This interaction fluctuates
the particle’s ...
