Fermion parity switches imprinted in the photonic field of cavity embedded Kitaev chains
Victor Fernandez Becerra, Olesia Dmytruk
We study a finite-length Kitaev chain coupled to a single mode photonic cavity. The topological phase of the finite-length Kitaev chain is characterized by the presence of fermion…
Quantized spin pumping in topological ferromagnetic-superconducting nanowires
V. Fernández Becerra, Mircea Trif, Timo Hyart
Semiconducting nanowires with strong spin-orbit coupling in the presence of induced superconductivity and ferromagnetism can support Majorana zero modes. We study the pumping due t…
Interplay of quantum spin Hall effect and spontaneous time-reversal symmetry breaking in electron-hole bilayers II: Zero-field topological superconductivity
Tania Paul, V. Fernández Becerra, Timo Hyart
It has been proposed that band-inverted electron-hole bilayers support a phase transition from an insulating phase with spontaneously broken time-reversal symmetry to a quantum spi…
Interplay of quantum spin Hall effect and spontaneous time-reversal symmetry breaking in electron-hole bilayers I: Transport properties
Tania Paul, V. Fernández Becerra, Timo Hyart
The band-inverted electron-hole bilayers, such as InAs/GaSb, are an interesting playground for the interplay of quantum spin Hall effect and correlation effects because of the smal…
Topological charge, spin and heat transistor
V. Fernández Becerra, Mircea Trif, Timo Hyart
Spin pumping consists in the injection of spin currents into a non-magnetic material due to the precession of an adjacent ferromagnet. In addition to the pumping of spin the preces…
Spontaneous emergence of Josephson junctions in homogeneous rings of single-crystal Sr2RuO4
Yuuki Yasui, Kaveh Lahabi, Victor Fernández Becerra +7
The chiral p-wave order parameter in SrRuO would make it a special case amongst the unconventional superconductors. A consequence of this symmetry is the…
Electronic properties of emergent topological defects in chiral -wave superconductivity
L. -F. Zhang, V. Fernández Becerra, L. Covaci +1
Chiral -wave superconductors in applied magnetic field can exhibit more complex topological defects than just conventional superconducting vortices, due to the two-component ord…
Dynamics of skyrmions and edge states in the resistive regime of mesoscopic \emph{p}-wave superconductors
V. Fernández Becerra, M. V. Milošević
In a mesoscopic sample of a chiral -wave superconductor, novel states comprising skyrmions and edge states have been stabilized in out-of-plane applied magnetic field. Using t…
Vortical versus skyrmionic states in mesoscopic \emph{p}-wave superconductors
V. Fernández Becerra, E. Sardella, F. M. Peeters +1
We investigate the superconducting states that arise as a consequence of mesoscopic confinement and a multi-component order parameter in the Ginzburg-Landau model for -wave su…
