DOI: 10.1103/physreva.110.052602

Abstract: Detecting the presence of multiple incoherent sources is a fundamental and challenging task for quantum imaging, especially within sub-Rayleigh region. In this paper, the discrimination of one-versus-two point-like incoherent sources in symmetric and asymmetric scenarios… read more here.

DOI: 10.1103/physrevd.98.053004

Abstract: Neutrino-nucleus scattering $\nu A\to \nu A$, in which the nucleus conserves its integrity, is considered. We show that elastic interactions keeping the nucleus in the same quantum state lead to a quadratic enhancement of the… read more here.

DOI: 10.1103/physreve.111.l013201

Abstract: The duration of incoherent XUV pulses down to the femtoseconds (fs) can be retrieved through a statistical analysis of the modulations on the observed radiation spectrum. Uncorrelated shot-noise fluctuations in the pulse temporal profile result… read more here.

DOI: 10.1103/vnt1-m777

Abstract: Incoherent stochastic processes added to unitary dynamics are typically deemed detrimental since they are expected to diminish quantum features such as superposition and entanglement. Instead of exhibiting energy-conserving persistent coherent motion, the dynamics of such… read more here.

DOI: 10.1109/lpt.2017.2655043

Abstract: We propose a distributed Raman amplifier available for dual-order co-propagating configuration with low-relative intensity noise (RIN) transfer. The first-order and second-order pumps are composed of incoherent and coherent light sources, respectively. By using the incoherent… read more here.

DOI: 10.1121/1.5014476

Abstract: Accurate estimation of the location and level of remote acoustic sources from recorded acoustic signals is attractive in many applications. In wind tunnel tests, where noise sources are commonly distributed and incoherent, high resolution array… read more here.

DOI: 10.3952/physics.v60i2.4226

Abstract: Parabolic quantum wells (PQWs) are known as a promising candidate for a compact terahertz (THz) source. PQWs have equidistant subbands that can be designed to be separated by few meV to meet the THz frequency… read more here.
