Mermin Devices for Generalized Dicke States

Roman V. Buniy, Thomas W. Kephart

We present here several new exact results for a number of entangled states: the W-state of three qubits and its generalization -- Dicke states for more than three qubits. We derive…

Tripartite entanglement of qudits

Roman V. Buniy, Thomas W. Kephart

We provide an in-depth study of tripartite entanglement of qudits. We start with a short review of tripartite entanglement invariants, prove a theorem about the complete list of al…

Decoherence and the Classes of Maximally Entangled States

Roman V. Buniy, Robert P. Feger, Thomas W. Kephart

Self-interactions and interaction with the environment tend to push quantum systems toward states of maximal entanglement. This is a definition of decoherence. We argue that these…

Macroscopic Superposition States in Isolated Quantum Systems

Roman V. Buniy, Stephen D. H. Hsu

For any choice of initial state and weak assumptions about the Hamiltonian, large isolated quantum systems undergoing Schrodinger evolution spend most of their time in macroscopic…

An iterative method for spherical bounces

Roman V. Buniy

We develop a new iterative method for finding approximate solutions for spherical bounces associated with the decay of the false vacuum in scalar field theories. The method works f…

Knotty inflation and the dimensionality of spacetime

Arjun Berera, Roman V. Buniy, Thomas W. Kephart +2

We suggest a structure for the vacuum comprised of a network of tightly knotted/linked flux tubes formed in a QCD-like cosmological phase transition and show that such a network ca…
