Geometric Visualizations of Quantum Mixed States and Density Matrices
Athanasios Kostikas, Yaroslav Valchyshen, Paul Cadden-Zimansky
This paper presents an introduction to geometric representations of quantum states in which each distinct quantum state, pure and mixed, corresponds to a unique point in a Euclidea…
Geometric Visualizations of Single and Entangled Qubits
Li-Heng Henry Chang, Shea Roccaforte, Ziyu Xu +1
The Bloch Sphere visualization of the possible states of a single qubit has proved a useful pedagogical and conceptual tool as a one-to-one map between qubit states and points in a…
Formation of the Landau level in hybrid graphene
P. Cadden-Zimansky, M. Shinn, G. T. Myers +3
The minimum of 4-terminal conductance occurring at its charge neutral point has proven to be a robust empirical feature of graphene, persisting with changes to temperature, applied…
Tunable Fractional Quantum Hall Phases in Bilayer Graphene
Patrick Maher, Lei Wang, Yuanda Gao +9
Symmetry breaking in a quantum system often leads to complex emergent behavior. In bilayer graphene (BLG), an electric field applied perpendicular to the basal plane breaks the inv…
Magnetoresistance measurements of Graphene at the Charge Neutrality Point
Yue Zhao, Paul Cadden-Zimansky, Fereshte Ghahari +1
We report on transport measurements of the insulating state that forms at the charge neutrality point of graphene in a magnetic field. Using both conventional two-terminal measurem…
Spin and valley quantum Hall ferromagnetism in graphene
Andrea F. Young, Cory R. Dean, Lei Wang +7
In a graphene Landau level (LL), strong Coulomb interactions and the fourfold spin/valley degeneracy lead to an approximate SU(4) isospin symmetry. At partial filling, exchange int…
