We investigate the possibility of having horizons inside various classical field configurations. Using the implicit function theorem, we show that models satisfying a certian set of criteria allow for...
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...
State independence for tunneling processes through black hole horizons and Hawking radiation
State independence black hole horizons Hawking radiation
2010/12/27
Tunneling processes through black hole horizons have recently been investigated in the framework of WKB theory discovering interesting interplay with the Hawking radiation. In this paper we instead ad...
Accelerated detectors and worldsheet horizons in AdS/CFT
Accelerated detectors worldsheet horizons

We use the AdS/CFT correspondence to discuss the response of an accelerated observer to the quantum vacuum fluctuations. In particular, we study heavy quarks probing a strongly coupled CFT by analysin...

Static isolated horizons: SU(2) invariant phase space, quantization, and black hole entropy
Static isolated horizons invariant phase space quantization black hole entropy
2010/12/20
We study the classical field theoretical formulation of static generic isolated horizons in a man-ifestly SU(2) invariant formulation. We show that the usual classical description requires revision in...

Micromorphology investigation of sepiolite bearing petrocalcic horizons formed from lacustrine sediments on the southern high planes of Texas and New Mexico
micromorphology investigation petrocalcic horizons lacustrine sediments
2011/11/8
The presence of sepiolite in soils has long been thought to have been attributed to inheritance from alternative parent material via secondary (eolian, alluvial) depositional processes due to sepiolit...
Existence of horizons in Robinson-Trautman spacetimes of arbitrary dimension

We derive the higher dimensional generalization of Penrose-Tod equation describing past horizon in Robinson-Trautman spacetimes with a cosmological constant and pure radiation. Results for D=4 dimensi...
At Closest Approach, New Horizons Takes Fresh Look at Jovian System（图）
Horizons spacecraft solar system
2007/3/6
27 February, 2007，To make the most of the fly-by opportunity, the New Horizons team came up with a plan for no less than 700 separate observations stretching from early January to March. This is actua...
18 January 2007，New Horizons’ encounter with the king of the planets is a byproduct of its trajectory, which will take it to Pluto in 2015. As it swings by Jupiter, the planet’s enormous gravitational...
November 29, 2006，The New Horizons team got a faint glimpse of the mission's distant, main planetary target when one of the spacecraft's telescopic cameras spotted Pluto for the first time.
Beidellite in E Horizons of Northern Idaho Spodosols Formed in Volcanic Ash
Northern Idaho Podzolization Smectite Soil genesis Tephra
2011/12/28
While soils formed in tephra are typically dominated by poorly crystalline clay minerals, the occurrence of smectite in E horizons of podzolized soils (Spodosols) has been well-documented. We have obs...
