Gauge-Field-Mediated Symmetry Breaking of Matters Under Electromagnetic Fields and Its Impact on Spin Dynamics
Uiseok Jeong, Esmaeil Taghizadeh Sisakht, Angel Rubio +3
When a condensed-matter system is subjected to external electromagnetic fields, the gauge-invariant formulation of physical operators must explicitly incorporate the gauge-field co…

Nuclear interference by electronic de-orthogonalisation
Matisse Wei-Yuan Tu, Angel Rubio, E. K. U. Gross
Interference is a universal consequence of superposition, yet in composite quantum systems it can encode correlations between subsystems. We show that in coupled electron-nuclear d…

Driving collective current excitations using light: The two-time approach
Chin Shen Ong, Denis Golež, Angel Rubio +2
We identify a distinct transverse collective excitation, which we name the "curron", arising from current-current interactions in a driven quantum metal. Unlike plasmons, which inv…
