Thermal relaxation asymmetry persists under inertial effects
Cai Dieball, Aljaž Godec
Relaxation phenomena far from thermal equilibrium feature a rich phenomenology, including the thermal relaxation asymmetry. The latter states that heating occurs faster than coolin…
Permutation-Invariant Spectral Learning via Dyson Diffusion
Tassilo Schwarz, Cai Dieball, Constantin Kogler +4
Diffusion models are central to generative modeling and have been adapted to graphs by diffusing adjacency matrix representations. The challenge of having up to such represent…
Strong Mpemba Effect Through a Reentrant Phase Transition
Kristian Blom, Doron Benyamin, Uwe Thiele +2
We investigate temperature quenches across the reentrant phase transition of the antiferromagnetic Ising model in a magnetic field and show that the strong direct and inverse Mpemb…
Purely quantum memory in closed systems observed via imperfect measurements
Jorge Tabanera-Bravo, Aljaž Godec
The detection and quantification of non-Markovianity, a.k.a. memory, in quantum systems is a central problem in the theory of open quantum systems. There memory is as a result of t…
Towards Markov-State Holography
Xizhu Zhao, Dmitrii E. Makarov, Aljaž Godec
Experiments, in particular on biological systems, typically probe lower-dimensional observables which are projections of high-dimensional dynamics. In order to infer consistent mod…
Dynamic Models for Two Nonreciprocally Coupled Fields: A Microscopic Derivation for Zero, One, and Two Conservation Laws
Kristian Blom, Uwe Thiele, Aljaž Godec
We construct dynamic models governing two nonreciprocally coupled fields for several cases with zero, one, and two conservation laws. Starting from two microscopic nonreciprocally…
