Eigenvalues and Low Energy Eigenvectors of Quantum Many-Body Systems
Ramis Movassagh
I first give an overview of the thesis and Matrix Product States (MPS) representation of quantum spin chains with an improvement on the conventional notation. The rest of this thes…
Unfrustration Condition and Degeneracy of Qudits on Trees
Matthew Coudron, Ramis Movassagh
We generalize the previous results of [1] by proving unfrustration condition and degeneracy of the ground states of qudits (d-dimensional spins) on a k-child tree with generic loca…
Bitemporal Dynamics Sinai Divergence, An Energetic Analog to Boltzmann's Entropy?
Otto E. Rossler, Ramis Movassagh
Sinai chaos is characterized by exponential divergence between neighboring trajectories of a point billiard. If the repulsive potential of the finite-diameter fixed particle in the…
On The Geometrical Description of Dynamical Stability II
Eduardo Cuervo-Reyes, Ramis Movassagh
Geometrization of dynamics using (non)-affine parametization of arc length with time is investigated. The two archetypes of such parametrizations, the Eisenhart and the Jacobi metr…
