- Abstract: We consider Lifshitz-type scalar theories with explicit breaking of the
Lorentz symmetry that, in addition, exhibit anisotropic scaling laws near the
ultraviolet fixed point. Using the proper time regularization method on the
spatial coordinates only, we derive the regularized form of the one-loop
effective potential in such theories. We study the main features of the
one-loop effective potential and, also, the RG flow of the scale-dependent
potential both in the IR and UV regimes. The beta functions for the couplings
are derived.

We show that a theory of emergent gravity arises, and that this can be recast according to the Ashtekar's formulation of general relativity.
As a consequence of the quantization procedure, the Hamiltonian is recovered to be non-Hermitian, and can be related to the complex action formalism.

and connections to phase-space and Keldysh field theory formulations [77.34726150561087]
We reformulate the technique of third quantization in a way that explicitly connects all three methods.
We first show that our formulation reveals a fundamental dissipative symmetry present in all quadratic bosonic or fermionic Lindbladians.
For bosons, we then show that the Wigner function and the characteristic function can be thought of as ''wavefunctions'' of the density matrix.

We show that introduction of harmonic and spin-dependent linear potentials sufficiently validates fTWA for longer times.
In particular, we focus on a finite two-dimensional system and show that at intermediate linear potential strength, the addition of a harmonic potential and spin dependence of the tilt, results in subdiffusive dynamics.

We consider the dynamics of excited local states in massive scalar field theory in an arbitrary spacetime dimension.
We identify different regimes of their evolution depending on the values of the field mass and the quench regularization parameter.
We also investigate the local quenches in massive scalar field theory on a cylinder and show that they cause an erratic and chaotic-like evolution of observables.

Our work presents a theory-independent way to characterize thermalization in quantum simulators and paves the way to quantum simulate condensed matter pump-probe experiments.
