Fokker-Planck approach to thermal fluctuations in antiferromagnetic systems
E. Martello, G. A. Falci, E. Paladino +1
We develop a Fokker-Planck approach to describe the dynamics of staggered magnetization and thermal fluctuations in a two-dimensional antiferromagnetic system with uniaxial anisotr…
Observation of chiral solitary waves in a nonlinear Aharonov-Bohm ring
Ivan Velkovsky, Anya Abraham, Enrico Martello +7
Nonlinearities can have a profound influence on the dynamics and equilibrium properties of discrete lattice systems. The simple case of two coupled modes with self-nonlinearities g…
Laser Annealed SiO2/Si1-xGex Scaffolds for Nanoscaled Devices, Synergy of Experiment and Computation
Damiano Ricciarelli, Jonas Müller, Guilhem Larrieu +11
Ultraviolet nanosecond laser annealing (UV-NLA) proves to be an important technique, particularly when tightly controlled heating and melting are necessary. In the realm of semicon…
Coexistence of stable and unstable population dynamics in a nonlinear non-Hermitian mechanical dimer
Enrico Martello, Yaashnaa Singhal, Bryce Gadway +2
Non-Hermitian two-site ``dimers'' serve as minimal models in which to explore the interplay of gain and loss in dynamical systems. In this paper, we experimentally and theoreticall…
Measuring the Adiabatic Non-Hermitian Berry Phase in Feedback-Coupled Oscillators
Yaashnaa Singhal, Enrico Martello, Shraddha Agrawal +3
The geometrical Berry phase is key to understanding the behaviour of quantum states under cyclic adiabatic evolution. When generalised to non-Hermitian systems with gain and loss,…
Synthetic Mechanical Lattices with Synthetic Interactions
Ritika Anandwade, Yaashnaa Singhal, Sai Naga Manoj Paladugu +8
Metamaterials based on mechanical elements have been developed over the past decade as a powerful platform for exploring analogs of electron transport in exotic regimes that are ha…
