Modular Index Invariants of Mumford Curves [PDF]

open access: yes, 2011
We continue an investigation initiated by Consani-Marcolli of the relation between the algebraic geometry of p-adic Mumford curves and the noncommutative geometry of graph C*-algebras associated to the action of the uniformizing p-adic Schottky group on ...

Ultrafast Multilevel Switching and Synaptic Behavior in a Planar Quantum Topological Memristor

open access: yesAdvanced Science, Volume 13, Issue 21, 13 April 2026.
Dry‐transferred Bi2Te3 layers enable a planar quantum topological memristor framework. In‐plane topological surface states facilitate ultrafast & low‐power operations. Coexisting analog and digital modes support current‐controlled multilevel states. PQTM exhibits 105 s retention, 103 cycles endurance, and reproducibility across 24 devices.

Classical theta constants vs. lattice theta series, and super string partition functions

open access: yes, 2010
Recently, various possible expressions for the vacuum-to-vacuum superstring amplitudes has been proposed at genus $g=3,4,5$. To compare the different proposals, here we will present a careful analysis of the comparison between the two main technical ...

Experimental Characterization and Modeling of High Hole Mobility GeSn Quantum Wells: The Role of Alloy Disorder Scattering

open access: yesSmall Science, Volume 6, Issue 4, April 2026.
This study reports record‐high hole mobility in undoped GeSn quantum wells, validated through magnetotransport measurements. By modeling the transport properties, the authors discover that alloy scattering in their material is significantly weaker than predicted for random alloys and previously studied materials.

Schottky uniformization and vector bundles over Riemann surfaces

open access: yes, 2001
We study a natural map from representations of a free group of rank g in GL(n,C), to holomorphic vector bundles of degree 0 over a compact Riemann surface X of genus g, associated with a Schottky uniformization of X.

Circle packings, renormalizations, and subdivision rules

open access: yesProceedings of the London Mathematical Society, Volume 132, Issue 4, April 2026.
Abstract In this paper, we use iterations of skinning maps on Teichmüller spaces to study circle packings and develop a renormalization theory for circle packings whose nerves satisfy certain subdivision rules. We characterize when the skinning map has bounded image.

Navigating the Ethereal Tightrope: The Nanogenerator Manipulates Neurons for Immune Equilibrium

open access: yesAdvanced Science, Volume 13, Issue 14, 9 March 2026.
This review explores how nanogenerators modulate neuroimmune responses, offering innovative strategies for treating neurological disorders. By interfacing with neural pathways, they enable precise control of immune activity, especially via vagus nerve stimulation.

On the numerical evaluation of algebro-geometric solutions to integrable equations

open access: yes, 2011
Physically meaningful periodic solutions to certain integrable partial differential equations are given in terms of multi-dimensional theta functions associated to real Riemann surfaces.

Bandgap Engineering of Nitrogen‐Doped Monolayer WSe2 Superlattice and its Application to Field Effect Transistor

open access: yesAdvanced Electronic Materials, Volume 12, Issue 5, 9 March 2026.
Random nitrogen substitution breaks translational symmetry in WSe2, creating localized impurity states near the band gap. In contrast, periodic nitrogen doping forms a superlattice, a man‐made crystal, that restores translational symmetry, broadening impurity states into dispersive sub‐bands that merge with the valence band. This enables controlled and
