Cascade of topological phase transitions and revival of topological zero modes in imperfect double helical liquids

This paper demonstrates that realistic imperfections, such as pairing asymmetries and magnetic disorder, in proximitized double helical liquids not only enrich the topological phase diagram by introducing cascades of transitions and a new BDI phase with single Majorana zero modes, but also reveal that disorder can serve as a tunable knob to revive and qualitatively reshape topological superconductivity.

Reducing strain fluctuations in quantum dot devices by gate-layer stacking

This paper demonstrates through numerical modeling that short-range strain fluctuations in Si/SiGe quantum dot devices, caused by metal gate electrodes, can be nearly totally suppressed by optimizing the thicknesses of overlapping gates and the intervening oxide layers to balance opposing strain mechanisms.

High-fidelity and robust controlled-Z gates for superconducting transmon qubits. I. Intrinsic errors and decoherence

This paper presents a comprehensive optimal-control framework for superconducting transmon qubits that achieves 12-ns high-fidelity controlled-Z gates with intrinsic errors suppressed to $2\times10^{-5}$ by systematically accounting for decoherence mechanisms and identifying dephasing sweet spots to enhance noise robustness.

Stabilizing and detecting electron fractionalization in the Hofstadter-Hubbard model

This paper demonstrates that increasing orbital flux in the half-filled triangular-lattice Hofstadter-Hubbard model stabilizes a $\mathrm{U}(1)_2$ chiral spin liquid phase where electrons fractionalize into gapped spinons and chargons, producing distinct spectral signatures that link band topology to intrinsic topological order.

Effect of Annealing on Maze Domains in Topological Insulator - Magnetic Multilayer Heterostructures

This study demonstrates that in-situ annealing at approximately 200°C enhances domain ordering and enables field-induced skyrmion nucleation in Bi $_2$ Se $_3$ -based topological insulator-magnetic multilayers while preserving the magnetic robustness of the interface up to 350°C despite structural deterioration of the topological insulator film.
