Objective classical branch structure in a many-body wavefunction from spatial redundancy
Speaker(s): Jess Riedel
Abstract: When the wavefunction of a macroscopic system unitarily evolves from a low-entropy initial state, there is good circumstantial evidence it develops "branches", i.e., a decomposition into orthogonal components that can't be distinguished from the corresponding incoherent mixture by feasible observati... read more

Symplectic covariant quantum Brownian motion: the harmonic oscillator of open systems
Speaker(s): Jess Riedel
Abstract: In the study of closed quantum system, the simple harmonic oscillator is ubiquitous because all smooth potentials look quadratic locally, and exhaustively understanding it is very valuable because it is exactly solvable. Although not widely appreciated, Markovian quantum Brownian motion (QBM) plays... read more

PIRSA:15110083  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Decoherence as a way to measure extremely soft collisions with Dark Matter
Speaker(s): Jess Riedel
Abstract: Quantum superpositions of matter are unusually sensitive to decoherence by tiny momentum transfers, in a way that can be made precise with a new diffusion standard quantum limit. Upcoming matter interferometers will produce unprecedented spatial superpositions of over a million nucleons. What sorts... read more

PIRSA:13120053  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Direct Detection of Classically Undetectable Dark Matter through Quantum Decoherence
Speaker(s): Jess Riedel
Abstract: Although various pieces of indirect evidence about the nature of dark matter have been collected, its direct detection has eluded experimental searches despite extensive effort. If the mass of dark matter is below 1 MeV, it is essentially imperceptible to conventional detection methods because negli... read more
