Extracting the anyonic exchange phase from co-tunneling through an open quantum dot
Felix Puster, Matthias Thamm, Bernd Rosenow
The elementary excitations of fractional quantum Hall states obey anyonic statistics, described by an exchange phase intermediate between the bosonic and fermionic values. We s…
The two-particle density matrix of a Luttinger liquid
Harini Radhakrishnan, Matthias Thamm, Hatem Barghathi +2
Two-particle coherence is the first level of the reduced-density-matrix hierarchy that contains correlations inaccessible to single-particle observables, yet analytic two-particle…
Anyon Exchange Phase from Antidot Interferometry
Matthias Thamm, Felix Puster, Bernd Rosenow
Quasiparticles in fractional quantum Hall systems are anyons, carrying a fraction of the electron charge. Exchanging two of them gives rise to a fractional exchange phase. While th…
Learning Dynamics of Chain-of-Thought State Tracking in a Solvable Transformer Model
Niklas Forner, Marcel Kühn, Matthias Thamm +1
Chain-of-thought generation can turn a multi-step computation into a sequence of locally checkable state updates, but the training dynamics by which transformers acquire such updat…
Physically Constrained Ensemble Gaussian Process Modelling for Expensive Quantum Systems with Heteroskedastic Noise
Arpan Biswas, Sutirtha Paul, Joseph Agada +2
Accurate modeling of quantum many-body systems often requires computationally expensive simulations such as Density Matrix Renormalization Group (DMRG) or Quantum Monte Carlo (QMC)…
Extracting the Anyonic Exchange Phase from Hanbury Brown-Twiss Correlations
Felix Puster, Matthias Thamm, Bernd Rosenow
In recent years, interferometry experiments in fractional quantum Hall devices have reported signatures of a fractional braiding phase for quasiparticles. It was noted, however, th…
