Magnetic and Metallic State at Intermediate Hubbard U Coupling in Multiorbital Models for Undoped Fe Pnictides
Rong Yu, Kien T. Trinh, Adriana Moreo +4
Multi-orbital Hubbard model Hamiltonians for the undoped parent compounds of the Fe-pnictide superconductors are here investigated using mean-field techniques. For a realistic four…
Extra Shared Entanglement Reduces Memory Demand in Quantum Convolutional Coding
Mark M. Wilde, Todd A. Brun
We show how extra entanglement shared between sender and receiver reduces the memory requirements for a general entanglement-assisted quantum convolutional code. We construct quant…
Channel State Prediction, Feedback and Scheduling for a Multiuser MIMO-OFDM Downlink
Hooman Shirani-Mehr, Daniel N. Liu, Giuseppe Caire
We consider the downlink of a MIMO-OFDM wireless systems where the base-station (BS) has M antennas and serves K single-antenna user terminals (UT) with K larger than or equal to M…
Reconstructing mass profiles of simulated galaxy clusters by combining Sunyaev-Zeldovich and X-ray images
S. Ameglio, S. Borgani, E. Pierpaoli +3
We present a method to recover mass profiles of galaxy clusters by combining data on thermal Sunyaev-Zeldovich (tSZ) and X-ray imaging, thereby avoiding to use any information on X…
Entanglement monogamy of multipartite higher-dimensional quantum systems using convex-roof extended negativity
Jeong San Kim, Anirban Das, Barry C. Sanders
We propose replacing concurrence by convex-roof extended negativity (CREN) for studying monogamy of entanglement (MoE). We show that all proven MoE relations using concurrence can…
CMBPol Mission Concept Study: Probing Inflation with CMB Polarization
Daniel Baumann, Mark G. Jackson, Peter Adshead +56
We summarize the utility of precise cosmic microwave background (CMB) polarization measurements as probes of the physics of inflation. We focus on the prospects for using CMB measu…
