Symmetries of Schrödinger Operator with Point Interactions

Letters in Mathematical Physics, 1998
The authors study the full four-parameter family of selfadjoint operators with point interactions and its behaviour under fundamental symmetry transformations. The paper starts with the discussion how the whole family of one-dimensional Schrödinger operators with point interactions can be described in terms of boundary conditions.

Representations of symmetry operators

Il Nuovo Cimento, 1958
Explicit representations in terms of the field variables are given for the charge conjugation, space inversion, and time reversal operators, for the case of free fields. These expressions are generalized to the case of coupled fields.

Symmetry Elements and Operations

Journal of Chemical Education, 1996
Symmetry Elements and Operations is a multimedia presentation that illustrates the basics of symmetry with three dimensional molecular models and simple text explanations. Three-dimensional graphics and animations are used to define and characterize the symmetry elements commonly encountered in chemical structures.

Entanglement as an operational symmetry

Rochester Conference on Coherence and Quantum Optics (CQO-11), 2019
The ability to replicate operations on one subsystem using operations on distant subsystems is a quintessential feature of entanglement. We formalize this notion and classify the states for which it holds to shed light on quantum and classical entanglement. This leads to an operational method for quantifying the entanglement in a quantum state.
