13/02/2018 - 13/02/2018A jellium pseudopotential generator for modelling the plasmonic response of complex-shaped nanostructures

Abstract:  

Experimental advances in the fabrication and control of nanometallic architectures, achieving nanometric and even sub-nanometric precision, have underlined the significance of quantum effects for systems with plasmonic functionalities, thereby challenging classical descriptions of their optical properties. In the interest of capturing both global geometrical features, as well as the intrinsically quantum nature of the electronic response at optical frequencies, we introduce a flexible jellium pseudopotential generator (JPG) for time-dependent density functional computations. We demonstrate the predictive capacity afforded by the JPG through a study of both single gold nanocubes, as well as of a sequence of morphological transformations that relate the cubic and spherical geometries. Plasmon-induced charge distributions for the cube are found to be in qualitative agreement with classical predictions, not withstanding deviations that originate in electronic delocalisation. The evolution in the absorption spectrum, during the cube-sphere transition, highlights the role of not only the polyhedral vertices, but also of the manner in which they are connected. Conclusions of this nature may bear important implications for the design of complex-shaped nanoparticles with desirable optical properties.

08/02/2018 - 08/02/2018Large deviations and quantum non-equilibrium

 

Abstract:  

 

I will review recent developments in applying dynamical large deviations

(LD) to quantum systems.  I will consider in particular open quantum

systems - quantum systems interacting with an environment - which in

many cases can be described in terms of quantum Markovian dynamics.  LD

methods provide a "thermodynamic" framework for understanding the

statistical properties of dynamics, revealing the existence of dynamical

phases and phase transitions, often associated to intermittent emission

patterns.  Problems of interest include interacting atomic ensembles,

quantum glasses, and systems where there is an interplay between

coherent transport and dissipation.  I will describe concepts relating

to quantum trajectory ensemble equivalence, prediction and

"retrodiction", matrix product states, and quantum Doob transforms. Time

permitting, I will also discuss the connection to ideas about slow

quantum relaxation and metastability.

19/01/2018 - 19/01/2018Interfacing magnetic molecules with 2D materials

 

Abstract:  

Graphene and other 2D materials have been a hot focus of interest in physics, chemistry and materials science. The emergence of van der Waals heterostructures formed by assembling two different monolayers of these materials through Van der Waals forces have opened new opportunities in this field. This concept can be further expanded by interfacing a layered 2D material with materials of other dimensionalities including 0D materials (molecules, nanoparticles,…), 1D materials (nanotubes, nanowires,…) and 3D materials, which can interact non only through VdW forces but also through covalent or ionic interactions [1].

In this talk I will focus on an emergent class of hybrid heterostructures formed by interfacing a 2D material with a molecular system. In particular, I will show how the properties of the “all surface” 2D material can be tuned through the interactions established with the molecular system. As 2D materials, I will focus on those exhibiting superconductivity or magnetism. As molecular systems, I will focus on stimuli-responsive magnetic molecules able to change their properties upon the application of an external stimulus (temperature, light or pressure) [2]. I will show that this concept can provide examples of smart molecular/2D heterostructures [3], which may be at the origin of a novel generation of hybrid materials and devices of direct application in highly topical fields like electronics, spintronics, molecular sensing and energy storage.
