Formation, prevalence, and stability of bouncing-ball quantum scars
Simo Selinummi, Joonas Keski-Rahkonen, Fartash Chalangari +1
Quantum scars correspond to enhanced probability densities along unstable classical periodic orbits. In recent years, research on quantum scars has extended to various systems incl…
Asymmetric Roughness of Elastic Interfaces at the Depinning Threshold
Esko Toivonen, Matti Molkkari, Esa Räsänen +1
Roughness of driven elastic interfaces in random media is typically understood to be characterized by a single roughness exponent . We show that at the depinning threshold, due…
Quantum Lissajous Scars
J. Keski-Rahkonen, A. Ruhanen, E. J. Heller +1
A quantum scar - an enhancement of a quantum probability density in the vicinity of a classical periodic orbit - is a fundamental phenomenon connecting quantum and classical mechan…
Dynamical Heart Beat Correlations during Running
Matti Molkkari, Giorgio Angelotti, Thorsten Emig +1
Fluctuations of the human heart beat constitute a complex system that has been studied mostly under resting conditions using conventional time series analysis methods. During physi…
On the control of Rydberg state population with realistic femtosecond laser pulses
Janne Solanpää ja Esa Räsänen
We investigate computationally a method for ultrafast preparation of alkali metal atoms in their Rydberg states using a three-dimensional model potential in the single active elect…
Controllable quantum scars in semiconductor quantum dots
J. Keski-Rahkonen, P. J. J. Luukko, L. Kaplan +2
Quantum scars are enhancements of quantum probability density along classical periodic orbits. We study the recently discovered phenomenon of strong, perturbation-induced quantum s…
