Critical dynamics of a scalar field near four spatial dimensions
Laura Batini, Eduardo Grossi
The critical dynamics of a non-conserved order parameter is generally expected to become overdamped at long distances, even when propagating modes occur at microscopic or intermedi…

False vacuum decay in long-range interacting quantum systems
Valerio Pagni, Laura Batini, Nicolò Defenu
We formulate false-vacuum decay in a mixed-field Ising chain with interactions as a spatially nonlocal Euclidean theory featuring a fractional spatial kinetic term $\…
