Covariant field theory of 3D massive fractons
Erica Bertolini, Matteo Carrega, Nicola Maggiore +1
We construct a covariant and gauge-invariant theory describing massive fractons in three spacetime dimensions, based on a symmetric rank-2 tensor field. The model includes a Chern-…

Controlling energy storage crossing quantum phase transitions in an integrable spin quantum battery
Riccardo Grazi, Daniel Sacco Shaikh, Maura Sassetti +2
We investigate the performance of a one-dimensional dimerized XY chain as a spin quantum battery. Such integrable model shows a rich quantum phase diagram that emerges through a ma…
