Cooper Pair Splitting by means of Graphene Quantum Dots
Z. B. Tan, D. Cox, T. Nieminen +4
Split Cooper pair is a natural source for entangled electrons which is a basic ingredient for quantum information in solid state. We report an experiment on a superconductor-graphe…
Incomplete measurement of work in a dissipative two level system
Klaara L. Viisanen, Samu Suomela, Simone Gasparinetti +3
We discuss work performed on a quantum two-level system coupled to multiple thermal baths. To evaluate the work, a measurement of photon exchange between the system and the baths i…
Search Methods for Tile Sets in Patterned DNA Self-Assembly
Mika Göös, Tuomo Lempiäinen, Eugen Czeizler +1
The Pattern self-Assembly Tile set Synthesis (PATS) problem, which arises in the theory of structured DNA self-assembly, is to determine a set of coloured tiles that, starting from…
Probability Estimates for Fading and Wiretap Channels from Ideal Class Zeta Functions
David Karpuk, Anne-Maria Ernvall-Hytönen, Camilla Hollanti +1
In this paper, new probability estimates are derived for ideal lattice codes from totally real number fields using ideal class Dedekind zeta functions. In contrast to previous work…
Electronic and transport properties in geometrically disordered graphene antidot lattices
Zheyong Fan, Andreas Uppstu, Ari Harju
A graphene antidot lattice, created by a regular perforation of a graphene sheet, can exhibit a considerable band gap required by many electronics devices. However, deviations from…
Breakdown of Potential Flow to Turbulence around a Sphere Oscillating in Superfluid He-4 above the Critical Velocity
W. Schoepe, R. Hänninen, M. Niemetz
The onset of turbulent flow around an oscillating sphere in superfluid He is known to occur at a critical velocity where is the circulation quantum and…
