We apply the squeezed state formalism to scalar field dark matter (e.g. axion) perturbations generated during inflation. As for inflationary perturbations, becomes highly as modes exit horizon. For long $H>m_\phi$ (with $H$ Hubble rate and $m_\phi$ mass) does not interact reheating, we follow its evolution exactly re-enter find that quantum remains after horizon re-entry hot big bang. This demo...

Severe traumatic brain injury impairs arousal and awareness, the two components of consciousness. Accurate diagnosis of a patient's level of consciousness is critical for determining treatment goals, access to rehabilitative services, and prognosis. The bedside behavioral examination, the current clinical standard for diagnosis of disorders of consciousness, is prone to misdiagnosis, a finding ...

We introduce a multi-mode squeezing coefficient to characterize entanglement in N-partite continuous-variable systems. The coefficient relates to the squeezing of collective observables in the 2N-dimensional phase space and can be readily extracted from the covariance matrix. Simple extensions further permit to reveal entanglement within specific partitions of a multipartite system. Application...

We show that by displacing two optical lattices with respect to each other, we may produce interactions similar to the ones describing ferro-magnetism in condensed matter physics. We also show that particularly simple choices of the interaction lead to spin-squeezing, which may be used to improve the sensitivity of atomic clocks. Spin-squeezing is generated even with partially, and randomly, fi...

We propose a method to infer the single-particle entropy of bosonic atoms in an optical lattice and to study the local evolution of entropy, spin squeezing and entropic inequalities for entanglement detection in such systems. This method is based on experimentally feasible measurements of non-nearestneighbour coherences. We study a specific example of dynamically controlling atom tunnelling bet...

A new kind of deformed calculus was introduced recently in studying of parabosonic coordinate representation. Based on this deformed calculus, a new deformation of Hermite polynomials is proposed, its some properties such as generating function, orthonormality, differential and integral representaions, and recursion relations are also discussed in this paper. As its applications, we calculate e...

We report on speciˇc signatures of one-mode squeezing due to multipulse control over quantum dynamics. As an important example, we discuss generation of squeezed bright light beams in optical parametric oscillator subjected to a periodic sequence of laser pulses. We show that the synchronized pulse control essentially improves the degree of integral squeezing, making it below the standard limit...
