Synaptic plasticity in Co/Nb:STO memristive devices: The role of oxygen vacancies
Walter Quiñonez, Anouk Goossens, Diego Rubi +2
Neuromorphic computing aims to develop energy-efficient devices that mimic biological synapses. One promising approach involves memristive devices that can dynamically adjust their…
On persistent energy currents at equilibrium in non-reciprocal systems
Svend-Age Biehs, Ivan Latella
We investigate the properties of the mean Poynting vector in global thermal equilibrium, which can be non-zero in non-reciprocal electromagnetic systems. Using dyadic Green's funct…
Radiative Corbino effect in nonreciprocal many-body systems
Ivan Latella, Philippe Ben-Abdallah
When a magnetic field is applied in the perpendicular direction to a metallic disk under the action of a radial bias voltage, a tangential electric current superimposes to the radi…
Electronic and magnetic properties of graphene-fluorographene nanoribbons: Controllable semiconductor-metal transition
R. M. Guzmán-Arellano, A. D. Hernández-Nieves, F. M. Peeters +1
We investigate the electronic and magnetic properties of graphene channels (--~nm wide) embedded within fluorographene, focusing on two distinct interfaces: the fully fluorin…
Nonlocal thermoelectricity in quantum wires as a signature of Bogoliubov-Fermi points
Juan Herrera Mateos, Leandro Tosi, Alessandro Braggio +2
We study nonlocal thermoelectricity in a superconducting wire subject to spin-orbit coupling and a magnetic field with a relative orientation between them. We calculate the cur…
Nanoscopic jets and filaments of superfluid He-4 at zero temperature: a DFT study
Francesco Ancilotto, Manuel Barranco, Marti Pi
Helium droplets produced by the instability of a cryogenic helium jet exiting a source chamber leads to the formation of He drops which are considered as ideal matrices for spectro…
Merging of superfluid Helium nanodroplets with vortices
J. M. Escartin, F. Ancilotto, M. Barranco +1
Within Density Functional Theory, we have investigated the coalescence dynamics of two superfluid helium nanodroplets hosting vortex lines in different relative orientations, which…
Coexistence of vortex arrays and surface capillary waves in spinning prolate superfluid He-4 nanodroplets
M. Pi, J. M. Escartin, F. Ancilotto +1
Within Density Functional Theory, we have studied the interplay between vortex arrays and capillary waves in spinning prolate He-4 droplets made of several thousands of helium atom…
A singlet triplet hole spin qubit in planar Ge
Daniel Jirovec, Andrea Hofmann, Andrea Ballabio +14
Spin qubits are considered to be among the most promising candidates for building a quantum processor. GroupIV hole spin qubits have moved into the focus of interest due to the eas…
Magnetic Droplet Solitons
Ferran Macià, Andrew D. Kent
Magnetic droplet solitons are dynamical magnetic textures that form due to an attractive interaction between spin waves in thin films with perpendicular magnetic anisotropy. Spin c…
Effects of the Zhang-Li Torque on Spin Torque nano Oscillators
Jan Albert, Ferran Macià, Joan Manel Hernàndez
Spin-torque nano-oscillators (STNO) are microwave auto-oscillators based on magnetic resonances having a nonlinear response with the oscillating amplitude, which provides them with…
Vorticity and quantum turbulence in the merging of superfluid Helium nanodroplets
José María Escartín, Francesco Ancilotto, Manuel Barranco +1
We have studied the merging of two He droplets at zero temperature, caused by their Van der Waals mutual attraction. During the early stages of the merging, density structures…
Spinning superfluid helium-4 nanodroplets
Francesco Ancilotto, Manuel Barranco, Marti Pi
We have studied spinning superfluid He nanodroplets at zero temperature using Density Functional theory. Due to the irrotational character of the superfluid flow, the shapes of…

Francesco Ancilotto, Manuel Barranco, Marti Pi +1
Two-dimensional flow past an infinitely long cylinder of nanoscopic radius in superfluid He-4 at zero temperature is studied by time-dependent density functional theory. The calcul…
Direct observation of enhanced magnetism in individual size- and shape-selected 3d transition metal nanoparticles
Armin Kleibert, Ana Balan, Rocio Yanes +10
Magnetic nanoparticles are important building blocks for future technologies ranging from nano-medicine to spintronics. Many related applications require nanoparticles with tailore…
Emergence of the stripe-domain phase in patterned Permalloy films
S. Voltan, C. Cirillo, H. J. Snijders +5
The occurrence of stripe domains in ferromagnetic Permalloy (Py=FeNi) is a well known phenomenon which has been extensively observed and characterized. This peculiar…
