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 $\…
Tachyonic and parametric instabilities in an extended bosonic Josephson junction
Laura Batini, Sebastian Erne, Jörg Schmiedmayer +1
We study the dynamics and decay of quantum phase coherence for Bose-Einstein condensates in tunnel-coupled quantum wires. The two elongated Bose-Einstein condensates exhibit a wide…
Particle production and hadronization temperature in the massive Schwinger model
Laura Batini, Lara Kuhn, Jürgen Berges +1
We study the pair production, string breaking, and hadronization of a receding electron-positron pair using the bosonized version of the massive Schwinger model in quantum electrod…
Real-time dynamics of false vacuum decay
Laura Batini, Aleksandr Chatrchyan, Jürgen Berges
We investigate false vacuum decay of a relativistic scalar field initialized in the metastable minimum of an asymmetric double-well potential. The transition to the true ground sta…
Dissipation dynamics of a scalar field
Laura Batini, Eduardo Grossi, Nicolas Wink
We investigate the dissipation rate of a scalar field in the vicinity of the phase transition and the ordered phase, specifically within the universality class of model A. This dis…
