Fourier expansions of Kac-Moody Eisenstein series and degenerate Whittaker vectors
Philipp Fleig, Axel Kleinschmidt, Daniel Persson
Motivated by string theory scattering amplitudes that are invariant under a discrete U-duality, we study Fourier coefficients of Eisenstein series on Kac-Moody groups. In particula…
Second Quantized Mathieu Moonshine
Daniel Persson, Roberto Volpato
We study the second quantized version of the twisted twining genera of generalized Mathieu moonshine, and prove that they give rise to Siegel modular forms with infinite product re…
Charge transport in InAs nanowire Josephson junctions
Simon Abay, Daniel Persson, Henrik Nilsson +5
We present an extensive experimental and theoretical study of the proximity effect in InAs nanowires connected to superconducting electrodes. We fabricate and investigate devices w…
Quantized conductance and its correlation to the supercurrent in a nanowire connected to superconductors
Simon Abay, Daniel Persson, Henrik Nilsson +4
We report conductance and supercurrent of InAs nanowires coupled to Al-superconducting electrodes with short channel lengths and good Ohmic contacts. The nanowires are suspended 15…
Quantum hypermultiplet moduli spaces in N=2 string vacua: a review
Sergei Alexandrov, Jan Manschot, Daniel Persson +1
The hypermultiplet moduli space M_H in type II string theories compactified on a Calabi-Yau threefold X is largely constrained by supersymmetry (which demands quaternion-Kählerity)…
Generalised Moonshine and Holomorphic Orbifolds
Matthias R. Gaberdiel, Daniel Persson, Roberto Volpato
Generalised moonshine is reviewed from the point of view of holomorphic orbifolds, putting special emphasis on the role of the third cohomology group H^3(G, U(1)) in characterising…
