Spin-Electric Coupling in Molecular Magnets
Mircea Trif, Filippo Troiani, Dimitrije Stepanenko +1
We study the triangular antiferromagnet Cu in external electric fields, using symmetry group arguments and a Hubbard model approach. We identify a spin-electric coupling caused…
Quantum gates between capacitively coupled double quantum dot two-spin qubits
Dimitrije Stepanenko, Guido Burkard
We study the two-qubit controlled-not gate operating on qubits encoded in the spin state of a pair of electrons in a double quantum dot. We assume that the electrons can tunnel bet…
Enhancement of electron spin coherence by optical preparation of nuclear spins
Dimitrije Stepanenko, Guido Burkard, Geza Giedke +1
We study a large ensemble of nuclear spins interacting with a single electron spin in a quantum dot under optical excitation and photon detection. When a pair of applied laser fiel…
