Non-Gaussian distribution of collective operators in quantum spin chains
New Journal of Physics, 2016 We numerically analyse the behavior of the full distribution of collective observables in quantum spin chains. While most of previous studies of quantum critical phenomena are limited to the first moments, here we demonstrate how quantum fluctuations at ...

Robust quantum state engineering through coherent localization in biased-coin quantum walks
EPJ Quantum Technology, 2018 We address the performance of a coin-biased quantum walk as a generator for non-classical position states of the walker. We exploit a phenomenon of coherent localization in the position space - resulting from the choice of small values of the coin ...

Birth of Comments on Atomic, Molecular and Optical Physics [PDF]
Physica Scripta, 2003 With this volume we start a new era for Comments on Atomic and Molecular Physics: subject coverage extended to Optical Physics and our joining Physica Scripta as part of this journal. We are very happy that after the last few years of problems with and changes of publishers we can look forward to a long and fruitful association in this venture.

Observation of a shape resonance of the positronium negative ion
Nature Communications, 2016 The Positronium negative ion is formed by two electrons bound to a positron, and experimental investigations of its states and energy levels are difficult due to its short lifetime.

Energetic cost of quantum control protocols
New Journal of Physics, 2019 We quantitatively assess the energetic cost of several well-known control protocols that achieve a finite time adiabatic dynamics, namely counterdiabatic and local counterdiabatic driving, optimal control, and inverse engineering.

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Successes and Difficulties in Calculating Atomic Oscillator Strengths and Transition Rates
Galaxies, 2018 There is an on-going need for accurate oscillator strengths to be used in astrophysical applications, particularly in plasma diagnostics and in the modelling of stellar atmospheres and the interstellar medium.

Biophysical approaches for studying viral entry
FEBS Letters, EarlyView.Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the
