Unified topological phase diagram of quantum Hall and superconducting vortex-lattice states
Daniil S. Antonenko, Liang Fu, Leonid I. Glazman
We present the global topological phase diagram of a two-dimensional electron gas placed in a quantizing magnetic field and proximitized by a superconducting vortex lattice. Our th…
Humanity's Last Exam
Long Phan, Alice Gatti, Ziwen Han +1144
Benchmarks are important tools for tracking the rapid advancements in large language model (LLM) capabilities. However, benchmarks are not keeping pace in difficulty: LLMs now achi…
Making s-wave superconductors topological with magnetic field
Daniil S. Antonenko, Liang Fu, Leonid. I Glazman
We show that a two-dimensional -wave superconductor may become topological in the presence of a magnetic field that leads to the formation of an Abrikosov vortex lattice. Below…
Effect of quasiparticles on the parameters of a gap-engineered transmon
Daniil S. Antonenko, Pavel D. Kurilovich, Francisco J. Matute-Cañadas +1
We evaluate the quasiparticle contribution to the frequency shift and relaxation rates of a transmon with the Josephson junctions connecting superconductors that have unequal energ…
Electrical switching of an unconventional odd parity magnet
Qian Song, Srdjan StavriÄ, Paolo Barone +11
Magnetic states with zero magnetization but non-relativistic spin splitting are outstanding candidates for the next generation of spintronic devices. Their electron-volt (eV) scale…
Mirror Chern Bands and Weyl Nodal Loops in Altermagnets
Daniil S. Antonenko, Rafael M. Fernandes, Jorn W. F. Venderbos
The electronic spectra of altermagnets are a fertile ground for nontrivial topology due to the unique interplay between time-reversal and crystalline symmetries. This is reflected…
