Momentum transport is anomalous in chiral p+ ip superfluids and superconductors in the
presence of textures and superflow. Using the gradient expansion of the semiclassical …

The Casimir effect arises from the zero-point energy of particles in momentum space
deformed by the existence of two parallel plates. For degrees of freedom on the lattice, its …

Non-Hermitian Hamiltonians are relevant to describe the features of a broad class of
physical phenomena, ranging from photonics and atomic and molecular systems to nuclear …

In this letter, we prove the existence of resummed expressions for the diagonal of the heat
kernel and the effective action of a quantum field which interacts with a scalar or an …

Inspired by the duality between gravity and defects in crystals, we study lattice field theory
with torsion. The torsion is realized by a line defect of a lattice, namely, a dislocation. For the …

Advances in engineering mesoscopic quantum devices have led to new material platforms
where electronic transport can be achieved on foldable structures. In this respect, we study …

We conjecture that the proper-time series expansion of the one-loop effective Lagrangian of
quantum electrodynamics can be summed in all terms containing the field-strength …

Recent work has analyzed how deformations due to the insertion of a defect in a flat
hexagonal lattice affect the ground state structure of an interacting fermion field theory. Such …

An approach that has been given promising results concerning investigations on the physics
of graphene is the so-called reduced quantum electrodynamics. In this work we consider the …

The Feynman propagator in curved spacetime admits an asymptotic (Schwinger-DeWitt)
series expansion in derivatives of the metric. Remarkably, all terms in the series containing …
