Preserving Symmetry: Spontaneous Symmetry Breaking through Decoherence

Sam Kuypers

Solids appear to have localised centres of mass, yet many-body quantum theory describes them using translationally symmetric models that preclude localisation. Conventionally, this…

Restoring Locality: The Heisenberg Picture as a Separable Description of Quantum Theory

Sam Kuypers

Local realism has been the subject of much discussion in modern physics, partly because our deepest theories of physics appear to contradict one another in regard to whether realit…

Measuring time in a timeless universe

Sam Kuypers, Simone Rijavec

Physical systems are usually assumed to evolve relative to an external time parameter, which is problematic because in quantum theory that parameter is not a physical observable. P…

On unorthodox qubits, with an application to the closed timelike curve problem

Samuel Kuypers

In orthodox quantum theory the observables of spacelike separated quantum systems commute. I shall call this the commutation constraint. It severely limits quantum theory's explana…

The quantum theory of time: a calculus for q-numbers

Samuel Kuypers

In quantum theory, physical systems are usually assumed to evolve relative to a c-number time. This c-number time is unphysical and has turned out to be unnecessary for explaining…

Everettian relative states in the Heisenberg picture

Samuel Kuypers, David Deutsch

Everett's relative-state construction in quantum theory has never been satisfactorily expressed in the Heisenberg picture. What one might have expected to be a straightforward proc…

Visualizing topological transport

Mariya A. Lizunova, Samuel Kuypers, Bernet Meijer +2

We present a mathematically simple procedure for explaining and visualizing the dynamics of quantized transport in topological insulators. The procedure serves to illustrate and cl…
