Dissipationless dynamics of spin supersolid states in a spin-1/2 triangular antiferromagnet with impurities
Yixuan Huang, Yuan Gao, Wei Li +2
The paper numerically studies how magnetic impurities affect the low‑energy excitations of spin‑supersolid phases in a spin‑1/2 easy‑axis triangular antiferromagnet, showing that t…
Comparison of spin-qubit architectures for quantum error-correcting codes
Mauricio Gutiérrez, Juan S. Rojas-Arias, David Obando +1
We investigate the performance of two quantum error-correcting codes, the surface code and the Bacon-Shor code, for implementation with spin qubits in silicon. In each case, we con…
Dissipative ground-state preparation of a quantum spin chain on a trapped-ion quantum computer
Kazuhiro Seki, Yuta Kikuchi, Tomoya Hayata +1
We demonstrate a dissipative protocol for ground-state preparation of a quantum spin chain on a trapped-ion quantum computer. As a first step, we derive a Kraus representation of a…
Repulsive-Interaction-Driven Topological Superconductivity in a Landau Level Coupled to an -Wave Superconductor
Koji Kudo, Ryota Nakai, Hiroki Isobe +2
A two-dimensional topologically nontrivial state of noninteracting electrons, such as the surface state of a three-dimensional topological insulator, is predicted to realize a topo…
Extended Haloscope Search and Exclusion of a Candidate Signal near 1.036 GHz
Saebyeok Ahn, Boris I. Ivanov, Ohjoon Kwon +33
We report a follow-up axion haloscope search near 1.036 GHz that completes and extends our previous work [Phys. Rev. X 14, 031023 (2024)], in which a portion of the HEMT-based data…
