Violating Bell's inequalities in vacuum

- B. Reznik, A. Retzker, J. Silman
- Physics
- 9 October 2003

We employ an approach wherein the ground state entanglement of a relativistic free scalar field is directly probed in a controlled manner. The approach consists of having a pair of initially… Expand

Entanglement from the Vacuum

- B. Reznik
- Physics
- 8 December 2002

We explore the entanglement of the vacuum of a relativistic field by letting a pair of causally disconnected probes interact with the field. We find that, even when the probes are initially… Expand

Spatial structures and localization of vacuum entanglement in the linear harmonic chain

We study the structure of vacuum entanglement for two complimentary segments of a linear harmonic chain, applying the modewise decomposition of entangled Gaussian states discussed by Boteno and… Expand

Measurement of time of arrival in quantum mechanics

- Y. Aharonov, J. Oppenheim, S. Popescu, B. Reznik, W. Unruh
- Physics
- 14 September 1997

It is argued that the time of arrival cannot be precisely defined and measured in quantum mechanics. By constructing explicit toy models of a measurement, we show that for a free particle it cannot… Expand

Modes of oscillation in radiofrequency Paul traps

- H. Landa, M. Drewsen, B. Reznik, A. Retzker
- Physics
- 18 June 2012

We examine the time-dependent dynamics of ion crystals in radiofrequency traps. The problem of stable trapping of general three-dimensional crystals is considered and the validity of the… Expand

Critical and noncritical long-range entanglement in Klein-Gordon fields

- S. Marcovitch, A. Retzker, M. Plenio, B. Reznik
- Physics
- 8 November 2008

We investigate the entanglement between two spatially separated intervals in the vacuum state of a free one-dimensional Klein-Gordon field by means of explicit computations in the continuum limit of… Expand

Quantum coherence of discrete kink solitons in ion traps.

- H. Landa, S. Marcovitch, A. Retzker, M. Plenio, B. Reznik

TLDR

Origin of the thermal radiation in a solid state analog of a black hole

- B. Reznik
- Physics
- 26 March 1997

An effective black-hole-like horizon occurs, for electromagnetic waves in matter, at a surface of singular electric and magnetic permeabilities. In a physical dispersive medium this horizon… Expand
