Entanglement and chaos in the kicked top
Maurice Lombardi, Alex Matzkin
The standard kicked top involves a periodically kicked angular momentum. By considering this angular momentum as a collection of entangled spins, we compute the bipartite entanglem…
Effect of conformations on charge transport in a thin elastic tube
Radha Balakrishnan, Rossen Dandoloff
We study the effect of conformations on charge transport in a thin elastic tube. Using the Kirchhoff model for a tube with any given Poisson ratio, cross-sectional shape and intrin…
Curvature induced quantum potential on deformed surfaces
Victor Atanasov, Rossen Dandoloff
We investigate the effect of curvature on the behaviour of a quantum particle bound to move on a surface. For the Gaussian bump we derive and discuss the quantum potential which re…
Fully frustrated Josephson junction ladders with Mobius boundary conditions as topologically protected qubits
Gerardo Cristofano, Vincenzo Marotta, Adele Naddeo +1
We show how to realize a ``protected'' qubit by using a fully frustrated Josephson Junction ladder (JJL) with Mobius boundary conditions. Such a system has been recently studied wi…
The Electronic Ground State Energy Problem: a New Reduced Density Matrix Approach
Eric Cances, Gabriel Stoltz, Mathieu Lewin
We present here a formulation of the electronic ground-state energy in terms of the second order reduced density matrix, using a duality argument. It is shown that the computation…
Geometric phase and quantum potential
R. Dandoloff
We show that the geometric phase of Levy-Leblond arises from a low of parallel transport for wave functions and point out that this phase belongs to a new class of geometric phases…
