Title: Causal Framework for Non-Linear Quantum Mechanics
Speaker: Surjeet Rajendran (Johns Hopkins Univ.)
Abstract: We add non-linear and state-dependent terms to quantum field theory.
We show that the resulting low-energy theory, non-linear quantum mechanics, is
causal, preserves probability and permits a consistent description of the
process of measurement. We explore the consequences of such terms and show that
non-linear quantum effects can be observed in macroscopic systems even in the
presence of de-coherence. We find that current experimental bounds on these
non-linearities are weak and propose several experimental methods to
significantly probe these effects. We also expose a fundamental vulnerability
of any non-linear modification of quantum mechanics - these modifications are
highly sensitive to cosmic history and their locally exploitable effects can
dynamically disappear if the observed universe has a tiny overlap with the
overall quantum state of the universe, as is predicted in conventional
inflationary cosmology. We identify observables that persist in this case and
discuss opportunities to detect them in cosmic ray experiments, tests of strong
field general relativity and current probes of the equation of state of the
universe. Non-linear quantum mechanics also enables novel gravitational
phenomena and may open new directions to solve the black hole information
problem and uncover the theory underlying quantum field theory and gravitation.
