Multi-cavity photonic systems, also known as photonic molecules, exhibit multi-well
potentials that may prove useful for advanced quantum and nonlinear optics,,,. A key …

Symmetry-breaking quantum phase transitions play a key role in several condensed matter,
cosmology and nuclear physics theoretical models,,. Its observation in real systems is often …

Enantio-conversion with the help of electromagnetic fields is an essential issue due to the
chirality dependence of many chemical, biological, and pharmaceutical processes. Here, we …

In this review, the concepts of quantum tunneling and parity violation are introduced in the
context of chiral molecules. A particle moving in a double well potential provides a good …

We study the temporal evolution of entanglement pertaining to two qubits interacting with a
thermal bath. In particular we consider the simplest nontrivial spin bath models where …

Recent experiments on macroscopic quantum tunneling reveal a nonexponential decay of
the number of atoms trapped in a quasibound state behind a potential barrier. Through both …

Here we consider stationary states for nonlinear Schrödinger equations in any spatial
dimension n with symmetric double well potentials. These states may bifurcate as the …

We propose a technical reformulation of the measurement problem of quantum mechanics,
which is based on the postulate that the final state of a measurement is classical; this …

After some suggestions about how to clarify the confused metaphysical distinctions between
dispositional and non‐dispositional or categorical properties, I review some of the main …

We consider the stationary solutions for a class of Schrödinger equations with a symmetric
double-well potential and a nonlinear perturbation. Here, in the semiclassical limit we prove …
