$mathbb{Z}_4$ transitions in quantum loop models on a zig-zag ladder

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Bowy M. La Rivière, Natalia Chepiga, , , | Summary: We study the nature of quantum phase transitions out of $mathbb{Z}_4$ ordered phases in quantum loop models on a zig-zag ladder. We report very rich critical behaviour that includes a pair of Ising transitions, a multi-critical Ashkin-Teller […]

Constant search time algorithm via topological quantum walks

Kavli Affiliate: Eliska Greplova | First 5 Authors: D. O. Oriekhov, Guliuxin Jin, Eliska Greplova, , | Summary: It is well-known that quantum algorithms such as Grover’s can provide a quadradic speed-up for unstructured search problems. By adding topological structure to a search problem, we show that it is possible to achieve a constant search-time […]

Probing universal critical scaling with scan-DMRG

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Natalia Chepiga, , , , | Summary: We explore the universal signatures of quantum phase transitions that can be extracted with the density matrix renormalization group (DMRG) algorithm applied to quantum chains with a gradient. We present high-quality data collapses for the order parameter and for the […]

Electron-Beam Writing of Atomic-Scale Reconstructions at Oxide Interfaces

Kavli Affiliate: Andrea D. Caviglia | First 5 Authors: Greta Segantini, Chih-Ying Hsu, Carl Willem Rischau, Patrick Blah, Mattias Matthiesen | Summary: The epitaxial growth of complex oxides enables the production of high-quality films, yet substrate choice is restricted to certain symmetry and lattice parameters, thereby limiting the technological applications of epitaxial oxides. In comparison, […]

The graphene squeeze-film microphone

Kavli Affiliate: P. G. Steeneken | First 5 Authors: M. P. Abrahams, J. Martinez, P. G. Steeneken, G. J. Verbiest, | Summary: Most microphones operate by detecting the sound-pressure induced motion of a membrane. In contrast, here we introduce a microphone that operates by monitoring the sound-pressure-induced modulation of the compressibility of air. By driving […]

High-fidelity single-spin shuttling in silicon

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Maxim De Smet, Yuta Matsumoto, Anne-Marije J. Zwerver, Larysa Tryputen, Sander L. de Snoo | Summary: The computational power and fault-tolerance of future large-scale quantum processors derive in large part from the connectivity between the qubits. One approach to increase connectivity is to engineer qubit-qubit interactions at […]

Spatial dependence of local density of states in semiconductor-superconductor hybrids

Kavli Affiliate: Srijit Goswami | First 5 Authors: Qingzhen Wang, Yining Zhang, Saurabh Karwal, Srijit Goswami, | Summary: Majorana bound states are expected to appear in one-dimensional semiconductor-superconductor hybrid systems, provided they are homogenous enough to host a global topological phase. In order to experimentally investigate the uniformity of the system, we study the spatial […]
