Symmetry and Asymmetry in Bosonic Gaussian Systems: A Resource-Theoretic Framework
Nikolaos Koukoulekidis, Iman Marvian
We study the interplay of symmetries and Gaussianity in bosonic systems, under closed and open dynamics, and develop a resource theory of Gaussian asymmetry. Specifically, we focus…

Optimal Distillation of Qubit Clocks
Sujay Kazi, Iman Marvian
We study coherence distillation under time-translation-invariant operations: given many copies of a quantum state containing coherence in the energy eigenbasis, the aim is to produ…

A resource theoretical unification of Mpemba effects: classical and quantum
Alessandro Summer, Mattia Moroder, Laetitia P. Bettmann +3
The Mpemba effect originally referred to the observation that, under certain thermalizing dynamics, initially hotter samples can cool faster than colder ones. This effect has since…
