Robust Wideband Interference Suppression Method for GNSS Array Antenna Receiver via Hybrid Beamforming Technique

Remote Sensing
Global navigation satellite system (GNSS) array antenna receivers are widely used to suppress wideband interference in navigation countermeasures. However, existing array antenna receivers all adopt a digital array structure and digital beamforming ...

A Broadband Shared-Aperture L/S/X-Band Dual-Polarized Antenna for SAR Applications

IEEE Access, 2019
This paper presents a novel tri-band antenna with dual polarizations and shared aperture. The proposed antenna operates at L-, S-, and X-bands with an approximate frequency ratio of 1:1.9:5.5.

Singular Mean-Field States: A Brief Review of Recent Results

Condensed Matter, 2020
This article provides a focused review of recent findings which demonstrate, in some cases quite counter-intuitively, the existence of bound states with a singularity of the density pattern at the center; the states are physically meaningful because ...

Cavity Casimir-Polder Forces and Their Effects in Ground-State Chemical Reactivity [PDF]

Physical Review X, 2018
Here we present a fundamental study on how the ground-state chemical reactivity of a molecule can be modified in a QED scenario, i.e., when it is placed inside a cavity and there is strong coupling between the cavity field and vibrational modes within ...

Nuclear ground-state masses and deformations: FRDM(2012) [PDF]

, 2015
We tabulate the atomic mass excesses and binding energies, ground-state shell-plus-pairing corrections, ground-state microscopic corrections, and nuclear ground-state deformations of 9318 nuclei ranging from 16O to A = 339 . The calculations are based on

Experimental signatures of spin superfluid ground state in canted antiferromagnet Cr2O3 via nonlocal spin transport [PDF]

Science Advances, 2018
We report direct experimental signatures for the spin superfluid ground state in canted antiferromagnets via nonlocal spin transport. Spin superfluid is a novel emerging quantum matter arising from the Bose-Einstein condensate (BEC) of spin-1 bosons.

Hybrid Monte Carlo algorithm for studying the Edwards-Anderson model

St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2022
The complexity of the study of spin glasses is related to their frustrations, due to which classical Monte Carlo algorithms experience serious difficulties when trying to calculate such systems.

Ground State Quantum Computation

, 1999
We formulate a novel ground state quantum computation approach that requires no unitary evolution of qubits in time: the qubits are fixed in stationary states of the Hamiltonian.
