Evidence of Rotational Fröhlich Coupling in Polaronic Trions
Maxim Trushin, Soumya Sarkar, Sinu Mathew +9
Electrons commonly couple through Fröhlich interactions with longitudinal optical phonons to form polarons. However, trions possess a finite angular momentum and should therefore c…
Finding good quantum codes using the Cartan form
Akshaya Jayashankar, Anjala M Babu, Hui Khoon Ng +1
We present a simple and fast numerical procedure to search for good quantum codes for storing logical qubits in the presence of independent per-qubit noise. In a key departure from…
Beyond Fortune 500: Women in a Global Network of Directors
Anna Evtushenko, Michael T. Gastner
In many countries, the representation of women on corporate boards of directors has become a topic of intense political debate. Social networking plays a crucial role in the appoin…
Enhanced hydrodynamic transport in near magic angle twisted bilayer graphene
Mohammad Zarenia, Indra Yudishtira, Shaffique Adam +1
Using the semiclassical quantum Boltzmann theory and employing the Dirac model with twist angle-dependent Fermi velocity we obtain results for the electrical resistivity, the elect…
Superconductivity from collective excitations in magic angle twisted bilayer graphene
Gargee Sharma, Maxim Trushin, Oleg P. Sushkov +2
A purely electronic mechanism is proposed for the unconventional superconductivity recently observed in twisted bilayer graphene (tBG) close to the magic angle. Using the Migdal-El…
Approximating posteriors with high-dimensional nuisance parameters via integrated rotated Gaussian approximation
Willem van den Boom, Galen Reeves, David B. Dunson
Posterior computation for high-dimensional data with many parameters can be challenging. This article focuses on a new method for approximating posterior distributions of a low- to…
Transfer learning for scalability of neural-network quantum states
Remmy Zen, Long My, Ryan Tan +5
Neural-network quantum states have shown great potential for the study of many-body quantum systems. In statistical machine learning, transfer learning designates protocols reusing…
Bayesian Inference for Latent Chain Graphs
Deng Lu, Maria De Iorio, Ajay Jasra +1
In this article we consider Bayesian inference for partially observed Andersson-Madigan-Perlman (AMP) Gaussian chain graph (CG) models. Such models are of particular interest in ap…
Dissipation-enabled hydrodynamic conductivity in a tunable bandgap semiconductor
Cheng Tan, Derek Y. H. Ho, Lei Wang +10
Electronic transport in the regime where carrier-carrier collisions are the dominant scattering mechanism has taken on new relevance with the advent of ultraclean two-dimensional m…
Many-impurity phonon Casimir effect in atomic chains
Aleksandr Rodin
Phonon Casimir effect is the long-range interaction between impurities in condensed matter systems, mediated by vacuum fluctuations of the phonon field. For pairs of impurities, th…
Voter model on networks partitioned into two cliques of arbitrary sizes
Michael T. Gastner, Kota Ishida
The voter model is an archetypal stochastic process that represents opinion dynamics. In each update, one agent is chosen uniformly at random. The selected agent then copies the cu…
Resolved Molecular Gas and Star Formation Properties of the Strongly Lensed z=2.26 Galaxy SDSS J0901+1814
Chelsea E. Sharon, Amitpal S. Tagore, Andrew J. Baker +8
We present ~1" resolution (~2 kpc in the source plane) observations of the CO(1-0), CO(3-2), Halpha, and [N II] lines in the strongly-lensed z=2.26 star-forming galaxy SDSS J0901+1…
CO Emission in Infrared-Selected Active Galactic Nuclei
Allison Kirkpatrick, Chelsea Sharon, Erica Keller +1
In order to better understand how active galactic nuclei (AGN) effect the interstellar media of their host galaxies, we perform a meta-analysis of the CO emission for a sample of $…
Monte Carlo Co-Ordinate Ascent Variational Inference
Lifeng Ye, Alexandros Beskos, Maria De Iorio +1
In Variational Inference (VI), coordinate-ascent and gradient-based approaches are two major types of algorithms for approximating difficult-to-compute probability densities. In re…
User-specified random sampling of quantum channels and its applications
Jun Yan Sim, Jun Suzuki, Berthold-Georg Englert +1
Random samples of quantum channels have many applications in quantum information processing tasks. Due to the Choi--Jamiołkowski isomorphism, there is a well-known correspondence b…
Quantum process tomography via optimal design of experiments
Yonatan Gazit, Hui Khoon Ng, Jun Suzuki
Quantum process tomography --- a primitive in many quantum information processing tasks --- can be cast within the framework of the theory of design of experiment (DoE), a branch o…
Phase coherent transport in bilayer and trilayer MoS2
Leiqiang Chu, Indra Yudhistira, Hennrik Schmidt +3
Bilayer MoS2 is a centrosymmetric semiconductor with degenerate spin states in the six valleys at the corners of the Brillouin zone. It has been proposed that breaking of this inve…
Linear algebraic techniques for spanning tree enumeration
Steven Klee, Matthew T. Stamps
Kirchhoff's Matrix-Tree Theorem asserts that the number of spanning trees in a finite graph can be computed from the determinant of any of its reduced Laplacian matrices. In many c…
Proper error bars for self-calibrating quantum tomography
Jun Yan Sim, Jiangwei Shang, Hui Khoon Ng +1
Self-calibrating quantum state tomography aims at reconstructing the unknown quantum state and certain properties of the measurement devices from the same data. Since the estimates…
