Half-integer vs. integer effects in quantum synchronization of spin systems

Ryan Tan, Christoph Bruder, Martin Koppenhöfer

We study the quantum synchronization of a single spin driven by an external semiclassical signal for spin numbers larger than , the smallest system to host a quantum self-su…

Giant spin current rectification due to the interplay of negative differential conductance and a non-uniform magnetic field

Kang Hao Lee, Vinitha Balachandran, Ryan Tan +2

In XXZ chains, spin transport can be significantly suppressed when the interactions in the chain and the bias of the dissipative driving are large enough. This phenomenon of negati…

Twist-tuned exchange and hysteresis in a bilayer van der Waals magnet

Priyanka Mondal, Sonu Verma, Wenze Lan +9

Moiré superlattices in twisted bilayers enable profound reconstructions of the electronic bandstructure, giving rise to correlated states with remarkable tunability. Extending thi…

Melting of the critical behavior of a Tomonaga-Luttinger liquid under dephasing

Jean-Sebastien Bernier, Ryan Tan, Chu Guo +2

Strongly correlated quantum systems often display universal behavior as, in certain regimes, their properties are found to be independent of the microscopic details of the underlyi…

Interaction-impeded relaxation in the presence of finite temperature baths

Ryan Tan, Xiansong Xu, Dario Poletti

We study the interplay between interactions and finite-temperature dephasing baths. We consider a double well with strongly interacting bosons coupled, via the density, to a bosoni…

Transfer learning for scalability of neural-network quantum states

Remmy Zen, Long My, Ryan Tan +5

Neural-network quantum states have shown great potential for the study of many-body quantum systems. In statistical machine learning, transfer learning designates protocols reusing…

Finding Quantum Critical Points with Neural-Network Quantum States

Remmy Zen, Long My, Ryan Tan +5

Finding the precise location of quantum critical points is of particular importance to characterise quantum many-body systems at zero temperature. However, quantum many-body system…

Classification of Lung Pathologies in Neonates using Dual Tree Complex Wavelet Transform

Sagarjit Aujla, Adel Mohamed, Ryan Tan +4

Annually 8500 neonatal deaths are reported in the US due to respiratory failure. Recently, Lung Ultrasound (LUS), due to its radiation free nature, portability, and being cheaper i…

Towards Quantifying Complexity with Quantum Mechanics

Ryan Tan, Daniel R. Terno, Jayne Thompson +2

While we have intuitive notions of structure and complexity, the formalization of this intuition is non-trivial. The statistical complexity is a popular candidate. It is based on t…

Magnetic Correlation Spectroscopy in CrSBr

Lukas Krelle, Ryan Tan, Daria Markina +8

CrSBr is an air-stable magnetic van der Waals semiconductor with strong magnetic anisotropy, where the interaction of excitons with the magnetic order enables the optical identific…

Light-cone and diffusive propagation of correlations in a many-body dissipative system

Jean-Sebastien Bernier, Ryan Tan, Lars Bonnes +3

We analyze the propagation of correlations after a sudden interaction change in a strongly interacting quantum system in contact with an environment. In particular, we consider an…
