Imaging the retina may provide a “window on the brain”, potentially enabling diagnosis of neural conditions. Two of these are malaria and Alzheimer’s disease (AD). AD is a neuro-degenerative disease, characterized by the formation of insoluble fibrils (plaques) composed of amyloid beta proteins. There is currently no definitive diagnosis available prior to death. Neurotoxic effects of amyloid...

We formulate quantum field theory in accelerated frames using Prigogine transformations. We then derive a background independent formulation of such transforms, and attempt a new formulation of quantum gravity.

The use of tailored laser pulses to control chemical processes has received much attention over the last 25 years, in part due to the rapid development of experimental pulse shaping techniques. This has permitted studies of control in an ever widening array of systems with increasing complexity (i.e., dimensionality for molecules). In this talk, I will present our computational approach for...

Intense femtosecond (10-15s) laser pulses can induce molecular dissociation via a broad range of pathways involving different electronic states. Furthermore, breaking the symmetry of a laser field allows control of these processes via the steering of electron motion, which is accomplished by superimposing electronic states of different parity. The symmetry break can be obtained, for example,...

We propose a technique to probe a quantum state of light in an optical cavity without significantly perturbing the photon field. We minimize the interaction of the probe with the field by arranging a setting where the largest contribution to the transition probability is cancelled. We show that we obtain very good resolution for measuring the photon population difference between any given...

Parametric down-conversion (PDC) and frequency conversion (FC) are two of the most common nonlinear processes used in quantum optics. In the first process a nonlinear crystal is used to down convert photons from a pump laser into pairs of photons correlated by energy and linear momentum conservation constraints. In the second process, the frequency of photons is increased or decreased after...

Nonlinear polarizations described by the χ(2) and χ(3) susceptibilities are central to many of the phenomena of classical nonlinear optics, including processes as diverse as second harmonic generation and four-wave mixing. These same susceptibilities govern quantum optical processes in which correlated photons are generated, such as spontaneous parametric down-conversion and spontaneous...

Until very recently, Free Electron Lasers (FEL) and synchrotrons offering femtosecond (10$^{-15}$s) slicing technology have been the only facilities able to generate femtosecond X-Ray pulses in the water window (280-530 eV) spectral range. Bringing ultrafast science to the soft-X-Ray offer a wide range of application like studying multielectron dynamics in gas phase atoms/molecules,...

Using the 100Hz line of the ALLS laboratory (Varennes, QC) we achieved 1.8$\mu$m central wavelength two-cycle pulses with an energy per pulse of more than 4mJ. High energy amplification of a white light OPA output and propagation through a noble gas filled 2m hollow core fiber were needed to obtained this high gain in output energy compared to what was previously achieved for ultrashort...

Experiments have observed a two-dimensional electron gas at the interface of two insulating oxides: strontium titanate ($\mathrm{SrTiO_3}$) and lanthanum aluminate ($\mathrm{LaAlO_3}$). These interfaces exhibit metallic, superconducting, and magnetic behaviours, which are strongly affected by impurities. We introduce a simple model to study the two-dimensional conductivity at ...

The critical nuclear charge ($Z_c$) for a three-body quantum mechanical system consisting of positive and negative charges is the minimum nuclear charge that can keep the system in a bound state. Here we present a study of the critical nuclear charge for two-electron (heliumlike) systems with infinite nuclear mass, and also a range of reduced mass ratio ($\mu/m$) up to 0.5. The results help...

Highly conductive and transparent silver nanowire networks have been applied as top electrode for p-Si/ZnO nanowire heterojunction photodiodes. Faster transient response and higher responsivity than the reference sample without deposition of silver nanowires has been obtained, which is attributed to improved carrier collection and transport efficiency through the silver nanowires network....

Curved or self-bending light has become a hot topic recently. It’s triggered by a newly self-accelerating non-diffractive beam, named Airy beam that propagates along a parabolic trajectory. This peculiar beam has led to many potential applications such as for example optical trapping and manipulation, plasma guidance, generation of light bullets, and routing of electrons and surface plasmons. ...

Borrowing the concept from time domain, non-stationary beams can be defined as a monochromatic coherent light whose intensity shapes vary during propagation. Therefore, the concept for non-stationary signal processing can be employed in analogy to study the linear dynamics of these beams. Typical examples of non-stationary beams are the self-accelerating beams featured by a transversely...

Plasma-mediated ablation by ultrafast lasers has been widely investigated for its application in material processing, bio-medical surgery and scientific research. High repetition rate burst-mode ultrafast lasers that output pulsetrains of >1MHz repetition rate have shown advantages including higher material removal rate, and extra degrees of control. Ablation by such lasers is a highly dynamic...

Global-scale distances for Quantum Key Distribution (QKD) can be achieved by utilizing an orbiting satellite acting as an intermediate node between two or more ground stations. With QKD states encoded in photon polarization, the total number of photons collected (or equivalently, the total received optical power) is the limiting factor to the secure key generation rate. In this study we...

In recent years, two-photon coincidence experiments have advanced both the understanding and subsequent applications of entangled photons. In particular, for femtosecond-timescale coincidence measurements, such as two-photon absorption or sum-frequency generation, special, spectrally-broadband (or temporally ultrashort) sources of entangled photons are required [1,2]. Periodically-poled...

We revisit fundamental properties of quantum information in light of a notion in one-shot information theory, namely smooth max-relative entropy. We show how these properties, in particular Strong Subadditivity of von Neumann entropy, follow from intuitive and easy to establish properties of the new notion.

Quantum control of molecular states is important in that it can be used to manipulate the behaviour of quantum systems. In particular, noble-metal nanoparticles can be used to enhance state decay rates in proximate quantum systems and modify local electromagnetic fields. This enhancement allows us to achieve a high level of control over the quantum dynamics of an atomic system. We use the...

Communication of quantum information, like its classical counterpart, requires data synchronization. In other words, one must be able to store the information and retrieve it when needed. An optical quantum memory is an interface that stores the information encoded in a photon and recalls it on demand. A promising protocol to implement a practical optical quantum memory is the Atomic Frequency...

We harness general relativistic effects to gain quantum control on a stationary qubit in an optical cavity by controlling the non-inertial motion of a different probe atom. Furthermore, we show that by considering relativistic trajectories of the probe, we enhance the fidelity of the quantum control.
