Orbifolds and the modular curve
Juan Martín Pérez, Florent Schaffhauser
We provide an account of the construction of the moduli stack of elliptic curves as an analytic orbifold. While intimately linked to Thurston's point of view on the subject (discre…
Temperature flow in pseudo-Majorana functional renormalization for quantum spins
Benedikt Schneider, Johannes Reuther, Matías G. Gonzalez +2
We implement the temperature flow scheme first proposed by Honerkamp and Salmhofer in Phys.~Rev.~B 64, 184516 (2001) into the pseudo-Majorana functional renormalization group metho…
Dilute measurement-induced cooling into many-body ground states
Josias Langbehn, Kyrylo Snizhko, Igor Gornyi +3
Cooling a quantum system to its ground state is important for the characterization of non-trivial interacting systems, and in the context of a variety of quantum information platfo…
Pseudo-fermion functional renormalization group with magnetic fields
Vincent Noculak, Johannes Reuther
The pseudo-fermion functional renormalization group is generalized to treat spin Hamiltonians with finite magnetic fields, enabling its application to arbitrary spin lattice models…
A Comparison of Models for Rolling Stock Scheduling
Boris Grimm, Rowan Hoogervorst, Ralf Borndörfer
A major step in the planning process of passenger railway operators is the assignment of rolling stock, i.e., train units, to the trips of the timetable. A wide variety of mathemat…
Robust Estimation of Nonlinear Properties of Quantum Processes
Yuqing Wang, Guoding Liu, Zhenhuan Liu +3
Accurate and robust estimation of quantum process properties is crucial for quantum information processing and quantum many-body physics. Combining classical shadow tomography and…
Active Learning approach to simulations of Strongly Correlated Matter with the Ghost Gutzwiller Approximation
Marius S. Frank, Denis G. Artiukhin, Tsung-Han Lee +4
Quantum embedding (QE) methods such as the Ghost Gutzwiller Approximation (gGA) offer a powerful approach to simulating strongly-correlated systems, but come with the computational…
Randomised benchmarking for characterizing and forecasting correlated processes
Xinfang Zhang, Zhihao Wu, Gregory A. L. White +12
The development of fault-tolerant quantum processors relies on the ability to control noise. A particularly insidious form of noise is temporally correlated or non-Markovian noise.…
Neural parameter calibration and uncertainty quantification for epidemic forecasting
Thomas Gaskin, Tim Conrad, Grigorios A. Pavliotis +1
The recent COVID-19 pandemic has thrown the importance of accurately forecasting contagion dynamics and learning infection parameters into sharp focus. At the same time, effective…
Unifying non-Markovian characterisation with an efficient and self-consistent framework
Gregory A. L. White, Petar Jurcevic, Charles D. Hill +1
Noise on quantum devices is much more complex than it is commonly given credit. Far from usual models of decoherence, nearly all quantum devices are plagued both by a continuum of…
Topological Signal Processing on Quantum Computers for Higher-Order Network Analysis
Caesnan M. G. Leditto, Angus Southwell, Behnam Tonekaboni +3
Predicting and analyzing global behaviour of complex systems is challenging due to the intricate nature of their component interactions. Recent work has started modelling complex s…
Nanoscopic Interfacial Hydrogel Viscoelasticity Revealed from Comparison of Macroscopic and Microscopic Rheology
Robert F. Schmidt, Henrik Kiefer, Robert Dalgliesh +2
Deviations between macrorheological and particle-based microrheological measurements are often considered a nuisance and neglected. We study aqueous poly(ethylene oxide) (PEO) hydr…
In-situ Synchrotron X-Ray Photoelectron Spectroscopy Study of Medium-Temperature Baking of Niobium for SRF Application
Alena Prudnikava, Yegor Tamashevich, Anna Makarova +2
In the present work the chemical composition of niobium surface upon 200-400 °C baking similar to "medium-temperature baking" and "furnace baking" of cavities is explored in-situ b…
Fast and robust cat state preparation utilizing higher order nonlinearities in Rydberg ensembles
S. Zhao, M. G. Krauss, T. Bienaime +4
In optical and solid-state architectures, low-order nonlinearities are commonly exploited for quantum state preparation due to their practical accessibility and controllability, wh…
Capturing long-range memory structures with tree-geometry process tensors
Neil Dowling, Kavan Modi, Roberto N. Muñoz +2
We introduce a class of quantum non-Markovian processes -- dubbed process trees -- that exhibit polynomially decaying temporal correlations and memory distributed across time scale…
A resonant sextuplet of sub-Neptunes transiting the bright star HD 110067
R. Luque, H. P. Osborn, A. Leleu +149
Planets with radii between that of the Earth and Neptune (hereafter referred to as sub-Neptunes) are found in close-in orbits around more than half of all Sun-like stars. Yet, thei…
Data-driven classification of individual cells by their non-Markovian motion
Anton Klimek, Debasmita Mondal, Stephan Block +2
We present a method to differentiate organisms solely by their motion based on the generalized Langevin equation (GLE) and use it to distinguish two different swimming modes of str…
Exponential stability of the flow for a generalised Burgers equation on a circle
Ana Djurdjevac, Armen Shirikyan
The paper deals with the problem of stability for the flow of the 1D Burgers equation on a circle. Using some ideas from the theory of positivity preserving semigroups, we establis…
Tensor-SqRA: Modeling the Transition Rates of Interacting Molecular Systems in terms of Potential Energies
Alexander Sikorski, Amir Niknejad, Marcus Weber +1
Estimating the rate of rare conformational changes in molecular systems is one of the goals of Molecular Dynamics simulations. In the past decades, a lot of progress has been done…
