Cotangent bundle reduction and Poincare-Birkhoff normal forms
Çiftçi, Ünver; Waalkens, Holger; Broer, Henk W. (Elsevier, 2014)In this paper we study a systematic and natural construction of canonical coordinates for the reduced space of a cotangent bundle with a free Lie group action. The canonical coordinates enable us to compute Poincare-Birkhoff ... -
Holonomy-reduced dynamics of triatomic molecules
Çiftçi, Ünver; Waalkens, Holger (Iop Publishing Ltd, 2011)Whereas it is easy to reduce the translational symmetry of a molecular system using, e. g., Jacobi coordinates, the situation is much more involved for rotational symmetry. In this paper, we address the latter problem using ... -
Phase space structures governing reaction dynamics in rotating molecules
Çiftçi, Ünver; Waalkens, Holger (Iop Publishing Ltd, 2012)Recently, the phase space structures governing reaction dynamics in Hamiltonian systems have been identified and algorithms for their explicit construction have been developed. These phase space structures are induced by ... -
Reaction Dynamics Through Kinetic Transition States
Çiftçi, Ünver; Waalkens, Holger (Amer Physical Soc, 2013)The transformation of a system from one state to another is often mediated by a bottleneck in the system's phase space. In chemistry, these bottlenecks are known as transition states through which the system has to pass ...
