Emergent ac Effect in Nonreciprocal Coupled Condensates
Ji Zou, Valerii K. Kozin, Daniel Loss +1
We report an emergent ac Josephson-like effect arising without external bias, driven by the interplay between nonreciprocity and nonlinearity in coupled condensates. Using a minima…

Heisenberg-limited metrology from the quantum-quench dynamics of an anisotropic ferromagnet
Z. M. McIntyre, Ji Zou, Jelena Klinovaja +1
The emerging field of quantum magnonics seeks to understand and harness the quantum properties of magnons -- quantized collective spin excitations in magnets. Squeezed magnon state…

Density Matrix Renormalization Group Study of Domain Wall Qubits
Guanxiong Qu, Ji Zou, Daniel Loss +1
Nanoscale topological spin textures in magnetic systems are emerging as promising candidates for scalable quantum architectures. Despite their potential as qubits, previous studies…
