Nonequilibrium spin-splitter effect in altermagnet superconductor hybrids
Tim Kokkeler, Tero T. Heikkilä, F. Sebastian Bergeret
We study the nonequilibrium spin-splitter effect in superconducting altermagnets and superconductor altermagnet hybrids by computing the alternating spin current and edge the spin…
Josephson anomalous vortices
Dan Crawford, Stefan Ilić, Pauli Virtanen +1
We show that vortices with circulating current, related with odd-frequency triplet pairing, appear in Josephson junctions where the barrier is a weak ferromagnet with strong spin-o…
Ideal quantum geometry of the surface states of rhombohedral graphite and its effects on the surface superconductivity
Guodong Jiang, Tero Heikkilä, Päivi Törmä
The interplay of quantum geometry and interactions determines the correlated state properties of flat bands. Here, we investigate the ideal quantum geometry (IQG), i.e., the proper…
Characterization of a quantum bus between two driven qubits
Alberto Hijano, Henri Lyyra, Juha T. Muhonen +1
We investigate the use of driven qubits coupled to a harmonic oscillator to implement a -gate. By dressing the qubits through an external driving field, the…
Optomechanical quantum bus for donor spins in silicon
Henri Lyyra, Cliona Shakespeare, Simeoni Ahopelto +6
Silicon is the foundation of current information technology, and a promising platform for future quantum information technology as silicon-based qubits exhibit some of the longest…
Quantum Geometric Helical Superconductivity
Aaron Dunbrack, Pauli Virtanen, Tero T. Heikkilä
Several physical phenomena in superconductors, such as helical superconductivity and the diode effect, rely on breaking time-reversal symmetry. This symmetry-breaking is usually ac…
