Anomalous Planar Hall Effect in Two-Dimensional Trigonal Crystals
Raffaele Battilomo, Niccoló Scopigno, Carmine Ortix
The planar Hall effect (PHE) is the appearance of an in-plane transverse voltage in the presence of coplanar electric and magnetic fields. Its hallmark is a characteristic -peri…
Berry Curvature Dipole in Strained Graphene: a Fermi Surface Warping Effect
Raffaele Battilomo, Niccolo' Scopigno, Carmine Ortix
It has been recently established that optoelectronic and non-linear transport experiments can give direct access to the dipole moment of the Berry curvature in non-magnetic and non…
Tuning topology in thin films of topological insulators by strain gradients
Raffaele Battilomo, Niccoló Scopigno, Carmine Ortix
We theoretically show that the coupling of inhomogeneous strains to the Dirac fermions of three-dimensional topological insulators (3DTI) in thin film geometries results in the occ…
Spin field-effect transistor in a quantum spin-Hall device
R. Battilomo, N. Scopigno, C. Ortix
We discuss the transport properties of a quantum spin-Hall insulator with sizable Rashba spin-orbit coupling in a disk geometry. The presence of topologically protected helical edg…
A topological quantum pump in serpentine-shaped semiconducting narrow channels
Sudhakar Pandey, Niccolo' Scopigno, Paola Gentile +2
We propose and analyze theoretically a one-dimensional solid-state electronic setup that operates as a topological charge pump in the complete absence of superimposed oscillating l…
Negative electronic compressibility and nanoscale inhomogeneity in ionic-liquid gated two-dimensional superconductors
G. Dezi, N. Scopigno, S. Caprara +1
When the electron density of highly crystalline thin films is tuned by chemical doping or ionic liq- uid gating, interesting effects appear including unconventional superconductivi…
Density inhomogeneities and Rashba spin-orbit coupling interplay in oxide interfaces
N. Bovenzi, S. Caprara, M. Grilli +3
There is steadily increasing evidence that the two-dimensional electron gas (2DEG) formed at the interface of some insulating oxides like LaAlO3/SrTiO3 and LaTiO3/SrTiO3 is strongl…
Non-volatile, reversible metal-insulator transition in oxide interfaces controlled by gate voltage and light
Mian Akif Safeen, Musa Mutlu Can, Amit Khare +6
The field-effect-induced modulation of transport properties of 2-dimensional electron gases residing at the LaAlO/SrTiO and LaGaO/SrTiO interfaces has been investig…
Density driven fluctuations in a two-dimensional superconductor
S. Hurand, J. Biscaras, N. Bergeal +11
In the vicinity of a phase transition, the order parameter starts fluctuating before vanishing at the critical point. The fluctuation regime, i.e. the way the ordered phase disappe…
Phase separation from electron confinement at oxide interfaces
N. Scopigno, D. Bucheli, S. Caprara +4
Oxide heterostructures are of great interest both for fundamental and applicative reasons. In particular the two-dimensional electron gas at the LaAlO/SrTiO or LaTiO/Sr…
Inhomogeneous multi-carrier superconductivity at LaXO3/SrTiO3 (X=Al or Ti) oxide interfaces
S. Caprara, D. Bucheli, N. Scopigno +5
Several experiments reveal the inhomogeneous character of the superconducting state that occurs when the carrier density of the two-dimensional electron gas formed at the LaXO3/SrT…
Possible mechanisms of electronic phase separation in oxide interfaces
N. Bovenzi, F. Finocchiaro, N. Scopigno +4
LaAlO3/SrTiO3 ad LaTiO3/SrTiO3 interfaces are known to host a strongly inhomogeneous (nearly) two-dimensional electron gas (2DEG). In this work we present three unconventional elec…
