Hybrid Analog-Digital Simulation of the Abelian Higgs model
Muhammad Asaduzzaman, Rayleigh W. Parker, Noah Goss +8
To investigate gauge theories with near-term quantum computers warrants exploration of nontraditional quantum simulators to find resource-efficient simulation protocols and ultimat…
Diagnosing Device Performance in Rydberg-Ladder Gauge Simulators with Cumulative Probabilities and Filtered Mutual Information
Avi Kaufman, Muhammad Asaduzzaman, Zane Ozzello +3
We study bitstring measurements from the publicly available Aquila Rydberg-atom platform using a two-leg ladder that encodes a truncated lattice gauge model as a practical benchmar…
Superconducting properties of thin film studied via the NMR of implanted Li
Md Asaduzzaman, Ryan M. L. McFadden, Edward Thoeng +10
We report measurements of the normal-state and superconducting properties of thin-film using Li -detected nuclear magnetic resonance (-NMR). In…
Improved entanglement entropy estimates from filtered bitstring probabilities
Avi Kaufman, James Corona, Zane Ozzello +3
Using the bitstring probabilities of ground states of bipartitioned ladders of Rydberg atoms, we calculate the mutual information, which is a lower bound on the corresponding bipar…
Depth-resolved Characterization of Meissner Screening Breakdown in Surface Treated Niobium
Edward Thoeng, Md. Asaduzzaman, Philipp Kolb +12
We report direct measurements of the magnetic field screening at the limits of the Meissner phase for two superconducting Nb samples. The samples are processed with two different s…
Measurements of the first-flux-penetration field in surface-treated and coated Nb: Distinguishing between surface pinning and an interface energy barrier
Md Asaduzzaman, Ryan M. L. McFadden, Edward Thoeng +2
We report measurements of the first-flux-penetration field in surface-treated and coated Nb samples using muon spin rotation (SR). Using thin Ag foils as energy moderators for t…
Comment on "Strong Meissner screening change in superconducting radio frequency cavities due to mild baking" [Appl. Phys. Lett. 104, 072601 (2014)]
Ryan M. L. McFadden, Md Asaduzzaman, Tobias Junginger
In a recent Letter by Romanenko et al., the authors used low-energy muon spin rotation (LE-SR) to measure the Meissner screening profile in cutouts from Nb superconducting radio…
Evidence for current suppression in superconductor-superconductor bilayers
Md Asaduzzaman, Ryan M. L. McFadden, Anne-Marie Valente-Feliciano +5
Superconducting radio frequency (SRF) cavities, which are critical components in many particle accelerators, need to be operated in the Meissner state to avoid strong dissipation f…
Depth-resolved measurements of the Meissner screening profile in surface-treated Nb
Ryan M. L. McFadden, Md Asaduzzaman, Thomas Prokscha +3
We report depth-resolved measurements of the Meissner screening profile in several surface-treated Nb samples using low-energy muon spin rotation (LE-SR). In these experiments,…
Depth-resolved measurement of the Meissner screening profile in a niobium thin film from spin-lattice relaxation of the implanted -emitter Li
Ryan M. L. McFadden, Md Asaduzzaman, Terry J. Buck +11
We report measurements of the Meissner screening profile in a Nb(300 nm)/AlO thin film using Li -detected nuclear magnetic resonance (-NMR). The NMR probe $…
A New High Parallel-Field Spectrometer at TRIUMF's -NMR Facility
Edward Thoeng, Ryan M. L. McFadden, Suresh Saminathan +16
A new high field spectrometer has been built to extend the capabilities of the -detected nuclear magnetic resonance (-NMR) facility at TRIUMF. This new beamline extension all…
Directional flow of solitons with asymmetric potential wells: Soliton diode
M. Asad-uz-zaman, U. Al Khawaja
We study the flow of bright solitons through two asymmetric potential wells. The scattering of a soliton by certain type of single potential wells, e.g., Gaussian or Rosen-Morse, i…
Modification of roton instability due to the presence of a second dipolar Bose-Einstein condensate

We study the behavior of two coupled purely dipolar Bose-Einstein condensates, each located in a cylindrically symmetric pancake-shaped external confining potential, as the separat…
Tuning the structural and dynamical properties of a dipolar Bose-Einstein condensate: Ripples and instability islands
M. Asad-uz-Zaman, D. Blume
It is now well established that the stability of aligned dipolar Bose gases can be tuned by varying the aspect ratio of the external harmonic confinement. This paper extends this i…
Aligned dipolar Bose-Einstein condensate in a double-well potential: From cigar-shaped to pancake-shaped
M. Asad-uz-Zaman, D. Blume
We consider a Bose-Einstein condensate (BEC), which is characterized by long-range and anisotropic dipole-dipole interactions and vanishing s-wave scattering length, in a double-we…
