Quantum field and uniformly accelerated oscillator  [PDF]
Hyeong-Chan Kim
Physics , 1998, DOI: 10.1103/PhysRevD.59.064024
Abstract: We present an exact treatment of the influences on a quantum scalar field in its Minkowski vacuum state induced by coupling of the field to a uniformly accelerated harmonic oscillator. We show that there are no radiation from the oscillator in the point of view of a uniformly accelerating observer. On the other hand, there are radiations in the point of view of an inertial observer. It is shown that Einstein-Podolsky-Rosen (EPR) like correlations of Rindler particles in Minkowski vacuum states are modified by a phase factor in front of the momentum-symmetric Rindler operators. The exact quantization of a time-dependent oscillator coupled to a massless scalar field was given.
Time domain Einstein-Podolsky-Rosen correlation  [PDF]
Nobuyuki Takei,Noriyuki Lee,Daiki Moriyama,J. S. Neergaard-Nielsen,Akira Furusawa
Physics , 2006, DOI: 10.1103/PhysRevA.74.060101
Abstract: We experimentally demonstrate creation and characterization of Einstein-Podolsky-Rosen (EPR) correlation between optical beams in the time domain. The correlated beams are created with two independent continuous-wave optical parametric oscillators and a half beam splitter. We define temporal modes using a square temporal filter with duration $T$ and make time-resolved measurement on the generated state. We observe the correlations between the relevant conjugate variables in time domain which correspond to the EPR correlation. Our scheme is extendable to continuous variable quantum teleportation of a non-Gaussian state defined in the time domain such as a Schr\"odinger cat-like state.
Einstein-Podolsky-Rosen Paradox and Antiparticle  [PDF]
Guang-jiong Ni,Hong Guan
Physics , 1999,
Abstract: The original version of Einstein-Podolsky-Rosen (EPR) paradox is discussed to show the completeness of Quantum Mechanics (QM). The unique solution leads to the wave function of antiparticle unambiguously, which implies the essential conformity between QM and Special Relativity (SR).
Bloch Oscillations of Einstein-Podolsky-Rosen States  [PDF]

Physics , 2015,
Abstract: Bloch Oscillations (BOs) of quantum particles manifest themselves as periodic spreading and re-localization of the associated wave functions when traversing lattice potentials subject to external gradient forces. Albeit BOs are deeply rooted into the very foundations of quantum mechanics, all experimental observations of this phenomenon so far have only contemplated dynamics of one or two particles initially prepared in separable local states, which is well described by classical wave physics. Evidently, a more general description of genuinely quantum BOs will be achieved upon excitation of a Bloch-oscillator lattice system by nonlocal states, that is, containing correlations in contradiction with local realism. Here we report the first experimental observation of BOs of two-particle Einstein-Podolsky-Rosen states (EPR), whose associated N-particle wave functions are nonlocal by nature. The time evolution of two-photon EPR states in Bloch-oscillators, whether symmetric, antisymmetric or partially symmetric, reveals unexpected transitions from particle antibunching to bunching. Consequently, the initial state can be tailored to produce spatial correlations akin to bosons, fermions or anyons. These results pave the way for a wider class of photonic quantum simulators.
Common misrepresentation of the Einstein-Podolsky-Rosen argument  [PDF]
V. Hnizdo
Physics , 2000,
Abstract: A frequently given version of the argument of Einstein, Podolsky and Rosen against the completeness of the quantum mechanical description is criticized as a misrepresentation that lacks the cogency of the original EPR argument.
Einstein-Podolsky-Rosen paradox and measurement of quantum system  [PDF]
Konstantin Kladko
Physics , 1999,
Abstract: Einstein-Podolsky-Rosen (EPR) paradox is considered in a relation to a measurement of an arbitrary quantum system . It is shown that the EPR paradox always appears in a gedanken experiment with two successively joined measuring devices.
Comment on "Why Einstein, Podolsky and Rosen did not prove that quantum mechanics is 'incomplete'"  [PDF]
Dirk Fischer
Physics , 2008,
Abstract: This comment on the recently published article "Why Einstein, Podolsky and Rosen did not prove that quantum mechanics is 'incomplete'" (arXiv:0805.0217) by J.H.Field shows that some conclusions, made in the referred-to article, result from an invalid use of dirac delta-distributions.
L'argument Einstein Podolsky Rosen (EPR) : Paradoxe, Alternative, Demonstration  [PDF]
Pierre Roussel
Physics , 2003,
Abstract: The EPR (Einstein, Podolsky, Rosen) argument and the Schrodinger cat paradox are revisited in relation with modern quantum optics and atomic physics and with the concept of decoherence. It is shown that the questions raised fifty years ago are still at the heart of our understanding of quantum physics today.
Indistinguishability and nonlocality in Einstein-Podolsky-Rosen experiment  [PDF]
Adonai S. Sant'Anna
Physics , 2000,
Abstract: Quasi-set theory allows us a non trivial relation between indistinguishability and nonlocality into the context of Einstein- Podolsky-Rosen experiment. Quasi-set theory is a set theory which provides a manner for dealing with collections of indistinguishable but not identical elementary particles.
Antiparticle in Light of Einstein-Podolsky-Rosen Paradox and Klein Paradox  [PDF]
Guang-jiong Ni,Hong Guan,Weimin Zhou,Jun Yan
Physics , 2000, DOI: 10.1088/0256-307X/17/6/002
Abstract: The original version of Einstein-Podolsky-Rosen (EPR) paradox and the Klein paradox of Klein-Gordon (KG) equation are discussed to show the necessity of existence of antiparticle with its wavefunction being fixed unambiguously. No concept of "hole" is needed.
