• Title: Spontaneous magnetism after a "remote" quench: a proposal to test Copenhagen interpretation
• Authors: Jianda Wu and Wenxin Ding
• Abstract summary: When entangled, electrons are no longer free Dirac electrons but become an excited state in a quantum-electrodynamics sense. A measurement of magnetism associated with entanglement-collapse of electrons becomes a test for Copenhagen interpretation in the reign of quantum-electrodynamics.

• Abstract: A change of quantum states for a quantum particle may lead to a change of physical field it exerts to the environment. We discuss such Gedankenexperiment for measuring the magnetic dipole fields associated with the electronic spins. When entangled, electrons are no longer free Dirac electrons but become an excited state in a quantum-electrodynamics sense. A measurement of magnetism associated with entanglement-collapse of electrons becomes a test for Copenhagen interpretation in the reign of quantum-electrodynamics. This proposal is equally applicable to other particles and their associated fields and interactions, such as neutrons and the electroweak force.

  We present a linearized effective theory using a Gaussian wavepacket description of a charged relativistic particle coupled to quantum electromagnetic fields. We address the issues of decoherence of flying electrons in free space and the impact of Unruh effect on the electrons. For a single electron accelerated in a uniform electric field, we identify the Unruh effect in the two-point correlators of the deviations from the electron's classical trajectory.

We predict a novel kind of bound quantum state in the simplest one-dimensional setup of two interacting particles in a box.

  We develop a theory of moir'e materials confined in a cavity consisting of thin polar van der Waals crystals. Nontrivial quantum geometry of moir'e flat bands leads to electromagnetic vacuum dressing of electrons. Results indicate that the cavity confinement enables one to control magnetic frustration of moir'e materials.

We simulate a Heisenberg evolution using laser-induced entangling interactions and collective spin rotations. We find that small subsystems equilibrate to near a recently predicted non-Abelian thermal state.

E-field sensitivities reported so far are rather weak, prompting the question of how to design molecules with stronger spin-electric couplings.
