Free-energy functional of the electronic potential for Schrödinger-Poisson theory
Vikram Jadhao, Kaushik Mitra, Francisco J. Solis +1
In the study of model electronic device systems where electrons are typically under confinement, a key obstacle is the need to iteratively solve the coupled Schrödinger-Poisson (SP…
Enhancing decoherence times in superconducting qubits via circuit design
Kaushik Mitra, C. A. R. Sá de Melo
We study decoherence effects in qubits coupled to environments that exhibit resonant frequencies in their spectral function. We model the coupling of the qubit to its environment v…
Hexatic, Wigner Crystal, and Superfluid Phases of Dipolar Bosons
Kaushik Mitra, C. J. Williams, C. A. R. Sá de Melo
The finite temperature phase diagram of two-dimensional dipolar bosons versus dipolar interaction strength is discussed. We identify the stable phases as dipolar superfluid (DSF),…
Superfluid and Fermi liquid phases of Bose-Fermi mixtures in optical lattices
Kaushik Mitra, C. J. Williams, C. A. R. Sá de Melo
We describe interacting mixtures of ultracold bosonic and fermionic atoms in harmonically confined optical lattices. For a suitable choice of parameters we study the emergence of s…
Multilevel effects in the Rabi oscillations of a Josephson phase qubit
S. K. Dutta, Frederick W. Strauch, R. M. Lewis +8
We present Rabi oscillation measurements of a Nb/AlOx/Nb dc superconducting quantum interference device (SQUID) phase qubit with a 100 um^2 area junction acquired over a range of m…
Quantum behavior of the dc SQUID phase qubit
Kaushik Mitra, F. W. Strauch, C. J. Lobb +3
We analyze the behavior of a dc Superconducting Quantum Interference Device (SQUID) phase qubit in which one junction acts as a phase qubit and the rest of the device provides isol…
