Gate-dependent offset charge shifts and anharmonicity in gatemon qubits in the weak tunneling regime
Utkan Güngördü, Rusko Ruskov, Silas Hoffman +3
Gatemon qubits are based on a superconductor-quantum dot-superconductor (S-QD-S) junction which enables in situ electrostatic tuning via a gate electrode. For a single-channel QD t…
The effects of alloy disorder on strongly-driven flopping mode qubits in Si/SiGe
Merritt P. R. Losert, Utkan Güngördü, S. N. Coppersmith +2
In Si quantum dot systems, large magnetic field gradients are needed to implement spin rotations via electric dipole spin resonance (EDSR). By increasing the effective electron dip…
Indications of a soft cutoff frequency in the charge noise of a Si/SiGe quantum dot spin qubit
Utkan Güngördü, J. P. Kestner
Characterizing charge noise is of prime importance to the semiconductor spin qubit community. We analyze the echo amplitude data from a recent experiment [Yoneda et al., Nat. Nanot…
Stability of skyrmion lattices and symmetries of quasi-two-dimensional chiral magnets
Utkan Güngördü, Rabindra Nepal, Oleg A. Tretiakov +2
Recently, there has been substantial interest in realizations of skyrmions, in particular in 2D systems due to increased stability resulting from reduced dimensionality. A stable s…
Fast control of topological vortex formation in BEC by counter-diabatic driving
Shumpei Masuda, Utkan Güngördü, Xi Chen +2
Topological vortex formation has been known as the simplest method for vortex formation in BEC of alkali atoms. This scheme requires inversion of the bias magnetic field along the…
