Non-analytic behavior of the Casimir force across a Lifshitz transition in a spin-orbit coupled material
Andrew A. Allocca, Justin H. Wilson, Victor Galitski
We propose the Casimir effect as a general method to observe Lifshitz transitions in electron systems. The concept is demonstrated with a planar spin-orbit coupled semiconductor in…
Theory of dynamic nuclear polarization and feedback in quantum dots
Sophia E. Economou, Edwin Barnes
An electron confined in a quantum dot interacts with its local nuclear spin environment through the hyperfine contact interaction. This interaction combined with external control a…
Landau-Zener population control and dipole measurement of a two level system bath
M. S. Khalil, S. Gladchenko, M. J. A. Stoutimore +3
Tunneling two level systems (TLS), present in dielectrics at low temperatures, have been recently studied for fundamental understanding and superconducting device development. Acco…
Robust quantum gates for singlet-triplet spin qubits using composite pulses
Xin Wang, Lev S. Bishop, Edwin Barnes +2
We present a comprehensive theoretical treatment of SUPCODE, a method for generating dynamically corrected quantum gate operations, which are immune to random noise in the environm…
Tunable Spin Qubit Coupling Mediated by a Multi-Electron Quantum Dot
V. Srinivasa, H. Xu, J. M. Taylor
We present an approach for entangling electron spin qubits localized on spatially separated impurity atoms or quantum dots via a multi-electron, two-level quantum dot. The effectiv…
Robust Two-Qubit Gates for Exchange-Coupled Qubits
F. Setiawan, Hoi-Yin Hui, J. P. Kestner +2
We present composite pulse sequences that perform fault-tolerant two-qubit gate operations on exchange-only quantum dot spin qubits in various experimentally relevant geometries. W…
Critical integer quantum Hall topology and the integrable Maryland model as a topological quantum critical point
Sriram Ganeshan, K. Kechedzhi, S. Das Sarma
One dimensional tight binding models such as Aubry-Andre-Harper (AAH) model (with onsite cosine potential) and the integrable Maryland model (with onsite tangent potential) have be…
Enhanced anti-ferromagnetic exchange between magnetic impurities in a superconducting host
Norman Y. Yao, Leonid I. Glazman, Eugene A. Demler +2
It is generally believed that superconductivity only weakly affects the indirect exchange between magnetic impurities. If the distance r between impurities is smaller than than the…
Electrical detection of topological quantum phase transitions in disordered Majorana nanowires
Benjamin M. Fregoso, Alejandro M. Lobos, S. Das Sarma
We study a disordered superconducting nanowire, with broken time-reversal and spin-rotational symmetry, which can be driven into a topological phase with end Majorana bound states…
Exact Classification of Landau-Majorana-Stückelberg-Zener Resonances By Floquet Determinants
Sriram Ganeshan, Edwin Barnes, S. Das Sarma
Recent experiments have shown that Landau-Majorana-Stuckelberg-Zener (LMSZ) interferometry is a powerful tool for demonstrating and exploiting quantum coherence not only in atomic…
Strain tuning of a quantum dot strongly coupled to a photonic crystal cavity
Shuo Sun, Hyochul Kim, Glenn S. Solomon +1
We demonstrate reversible strain-tuning of a quantum dot strongly coupled to a photonic crystal cavity. We observe an average redshift of 0.45 nm for quantum dots located inside th…
Density of states of disordered topological superconductor-semiconductor hybrid nanowires
Jay D. Sau, S. Das Sarma
Using Bogoliubov-de Gennes (BdG) equations we numerically calculate the disorder averaged density of states of disordered semiconductor nanowires driven into a putative topological…

Silvan Schmid, Tolga Bagci, Emil Zeuthen +12
Due to their exceptional mechanical and optical properties, dielectric silicon nitride (SiN) micromembrane resonators have become the centerpiece of many optomechanical experiments…

We theoretically consider the effect of plasmon collective modes on the frequency-dependent conductivity of graphene in the presence of the random static potential of charged impur…
The Resonant Exchange Qubit
J. Medford, J. Beil, J. M. Taylor +4
We introduce a solid-state qubit in which exchange interactions among confined electrons provide both the static longitudinal field and the oscillatory transverse field, allowing r…
Electrically-protected resonant exchange qubits in triple quantum dots
J. M. Taylor, V. Srinivasa, J. Medford
We present a modulated microwave approach for quantum computing with qubits comprising three spins in a triple quantum dot. This approach includes single- and two-qubit gates that…
Simultaneous Spin-Charge Relaxation in Double Quantum Dots
V. Srinivasa, K. C. Nowack, M. Shafiei +2
We investigate phonon-induced spin and charge relaxation mediated by spin-orbit and hyperfine interactions for a single electron confined within a double quantum dot. A simple toy…
Self-Consistent Measurement and State Tomography of an Exchange-Only Spin Qubit
J. Medford, J. Beil, J. M. Taylor +7
We report initialization, complete electrical control, and single-shot readout of an exchange-only spin qubit. Full control via the exchange interaction is fast, yielding a demonst…
Imaging topological edge states in silicon photonics
