Micro-wires self-assembled and 3D-connected with the help of a nematic liquid crystal
Hakam Agha, Jean-Baptiste Fleury, Yves Galerne
We discuss a method for producing automatic 3D connections at right places between substrates in front to one another. The idea is based on the materialization of disclination line…
Understanding Branly's effect through Induced Tunnelling
Charles Hirlimann
At the end of the nineteenth century Édouard Branly discovered that the electrical resistance of a granular metallic conductor could drop by several orders of magnitude when excite…
Reconfigurable long-range phonon dynamics in optomechanical arrays
André Xuereb, Claudiu Genes, Guido Pupillo +2
We investigate periodic optomechanical arrays as reconfigurable platforms for engineering the coupling between multiple mechanical and electromagnetic modes and for exploring many-…
Scanning-gate-induced effects in nonlinear transport through nanostructures
Cosimo Gorini, Dietmar Weinmann, Rodolfo A. Jalabert
We investigate the effect of a scanning gate tip in the nonlinear quantum transport properties of nanostructures. Generally, we predict that the symmetry of the current-voltage cha…
Transmission phase of a quantum dot and statistical fluctuations of partial-width amplitudes
Rodolfo A. Jalabert, Guillaume Weick, Hans A. Weidenmüller +1
Experimentally, the phase of the amplitude for electron transmission through a quantum dot (transmission phase) shows the same pattern between consecutive resonances. Such universa…
Multiscale and multimodel simulation of Bloch point dynamics
Christian Andreas, Attila Kákay, Riccardo Hertel
We present simulation results on the structure and dynamics of micromagnetic point singularities with atomistic resolution. This is achieved by embedding an atomistic computational…
Non-reciprocal Oersted field contribution to the current-induced frequency shift of magnetostatic surface waves
Mohammad Haidar, Matthieu Bailleul, Mikhail Kostylev +1
The influence of an electrical current on the propagation of magnetostatic surface waves is investigated in a relatively thick (40 nm) permalloy film both experimentally and theore…
Dynamics of entanglement entropy and entanglement spectrum crossing a quantum phase transition
Elena Canovi, Elisa Ercolessi, Piero Naldesi +2
We study the time evolution of entanglement entropy and entanglement spectrum in a finite-size system which crosses a quantum phase transition at different speeds. We focus on the…
Nonperturbative treatment of coupled anharmonic vibrational molecular modes analyzed by 2D-infrared spectroscopy
Kuo Kan Liang, Albert A. Villaeys
In the present work, we give an analytical non-perturbative treatment of mode-mode coupling and anharmonicity occurring in molecular vibrational systems analyzed by 2D-infrared spe…
Tunable electronic correlation effects in nanotube-light interactions
Yuhei Miyauchi, Zhengyi Zhang, Mitsuhide Takekoshi +9
Electronic many-body correlation effects in one-dimensional (1D) systems such as carbon nanotubes have been predicted to modify strongly the nature of photoexcited states. Here we…
Topological phase transitions driven by non-Abelian gauge potentials in optical square lattices
M. Burrello, I. C. Fulga, E. Alba +2
We analyze a tight-binding model of ultracold fermions loaded in an optical square lattice and subjected to a synthetic non-Abelian gauge potential featuring both a magnetic field…
Semimetal-superfluid quantum phase transitions in 2D and 3D lattices with Dirac points
Gabriel Mazzucchi, Luca Lepori, Andrea Trombettoni
We study the superfluid properties of attractively interacting fermions hopping in a family of 2D and 3D lattices in the presence of synthetic gauge fields having π-flux per plaque…

We present a theoretical study based on the Anderson model of the transport properties of a Kondo impurity (atom or quantum dot) connected to ferromagnetic leads, which can sustain…
Adiabatic Tracking of a State: a New Route to Nonequilibrium Physics
M. Moliner, P. Schmitteckert
We present a novel numerical approach to track the response of a quantum system to an external perturbation that is progressively switched-on. The method is applied, within the fra…
