Probing structural and dynamic properties of MAPbCl3 hybrid perovskite using Mn2+ EPR

Hybrid methylammonium (MA) lead halide perovskites have emerged as materials exhibiting excellent photovoltaic performance related to their rich structural and dynamic properties. Here, we use multifrequency (X-, Q-, and W-band) electron paramagnetic reson ...

Revealing higher-order light and matter energy exchanges using quantum trajectories in ultrastrong coupling

Fabrizio Minganti

The dynamics of open quantum systems is often modeled using master equations, which describe the expected outcome of an experiment (i.e., the average over many realizations of the same dynamics). Quantum trajectories, instead, model the outcome of ideal si ...

A simple model of mechanical effects to estimate metabolic cost of human walking

Auke Ijspeert, Salman Faraji, Amy Roning Wu

Since the advent of energy measurement devices, gait experiments have shown that energetic economy has a large influence on human walking behavior. However, few cost models have attempted to capture the major energy components under comprehensive walking c ...

Dynamics of a flexible helical filament rotating in a viscous fluid near a rigid boundary

Pedro Miguel Nunes Pereira de Almeida Reis

We study the effect of a no-slip rigid boundary on the dynamics of a flexible helical filament rotating in a viscous fluid, at low Reynolds number conditions (Stokes limit). This system is taken as a reduced model for the propulsion of uniflagellar bacteri ...

Propulsion and Instability of a Flexible Helical Rod Rotating in a Viscous Fluid

Pedro Miguel Nunes Pereira de Almeida Reis

We combine experiments with simulations to investigate the fluid-structure interaction of a flexible helical rod rotating in a viscous fluid, under low Reynolds number conditions. Our analysis takes into account the coupling between the geometrically nonli ...

Quantum critical scaling for a Heisenberg spin-1/2 chain around saturation

Henrik Moodysson Rønnow, Mingee Chung

We demonstrate quantum critical scaling for an S = 1/2 Heisenberg antiferromagnetic chain compound Cu(C4H4N2)(NO3)(2) in a magnetic field around saturation, by analyzing previously reported magnetization [Y. Kono et al., Phys. Rev. Lett. 114, 037202 (2015) ...

Desiccation shrinkage of non-clayey soils: a numerical study

Lyesse Laloui, Hervé Péron

A meso-scale model based on the evolution of the pore system and idealized as bimodal is numerically examined. A simplified evolution of the model reveals a series of characteristics that qualitatively agree with the observed macroscopic experimental findi ...

Trajectory-based solution of the nonadiabatic quantum dynamics equations: an on-the-fly approach for molecular dynamics simulations

Ursula Röthlisberger, Ivano Tavernelli, Basile Curchod

The non-relativistic quantum dynamics of nuclei and electrons is solved within the framework of quantum hydrodynamics using the adiabatic representation of the electronic states. An on-the-fly trajectory-based nonadiabatic molecular dynamics algorithm is d ...

Quantum fluid properties of polaritons in semiconductor microcavities

Romuald Houdré, Cristiano Ciuti

In semiconductor quantum wells embedded in a high finesse microcavity, excitons, which are bound electron-hole systems, strongly couple to photons, forming mixed quasi-particles called polaritons. Polaritons can be coherently excited by an incident laser f ...
