Higher-Order Topological Systems and Their Sub-Symmetry-Protected Topology
Myungjun Kang, Wonjun Sung, Sonu Verma +1
Symmetry and topology are essential principles in topological physics. Recently, the idea of sub-symmetry-protected topology -- where some of the original symmetries are broken whi…
Dynamical signatures of superfluidity and shear rigidity in different phases of a dipolar Bose-Einstein condensate
Soumyadeep Halder, Hari Sadhan Ghosh, Axel Pelster +1
We show that a sudden change in the polarization direction of the magnetic dipole moments of the atoms in a dipolar Bose-Einstein condensate (BEC) can serve as a useful dynamical p…
Boltzmann transport theory of magnon-exciton drag
Zakhar A. Iakovlev, Akashdeep Kamra, Mikhail M. Glazov
We develop a microscopic theory of magnon-exciton drag effect in a bilayer van der Waals antiferromagnetic semiconductor CrSBr. Effective exciton-magnon coupling arises from an orb…
Unveiling Micrometer-Range Spin-Wave Transport in Artificial Spin Ice
Syamlal Sankaran Kunnath, Mateusz Zelent, Pawel Gruszecki +1
Artificial spin ice (ASI) systems exhibit fascinating phenomena, such as frustration and the formation of magnetic monopole states, and Dirac strings. However, exploring the wave p…
Twist-tuned exchange and hysteresis in a bilayer van der Waals magnet
Priyanka Mondal, Sonu Verma, Wenze Lan +9
Moiré superlattices in twisted bilayers enable profound reconstructions of the electronic bandstructure, giving rise to correlated states with remarkable tunability. Extending this…
The Power of Regular Constraint Propagation (Technical Report)

The past decade has witnessed substantial developments in string solving. Motivated by the complexity of string solving strategies adopted in existing string solvers, we investigat…
Large-Scale Linear Energy System Optimization: A Systematic Review on Parallelization Strategies via Decomposition
Lars Hadidi, Leonard Göke, Maximilian Hoffmann +7
As renewable energy integration, sector coupling, and spatiotemporal detail increase, energy system optimization models grow in size and complexity, often pushing solvers to their…
Exciton transport driven by spin excitations in an antiferromagnet
Florian Dirnberger, Sophia Terres, Zakhar A. Iakovlev +5
A new class of optical quasiparticles called magnetic excitons recently emerged in magnetic van der Waals materials. Akin to the highly effective strategies developed for electrons…
Quantum sensing magnonic number states using a bosonic mode as the probe
Bashab Dey, Sonu Verma, Mathias Weiler +1
Sensing number states of a magnonic mode has been accomplished using a superconducting qubit by realizing an effective dispersive interaction between the two systems. Here, we theo…
Superstudent intelligence in thermodynamics
Rebecca Loubet, Pascal Zittlau, Marco Hoffmann +6
In this short note, we report and analyze a striking event: OpenAI's large language model o3 has outwitted all students in a university exam on thermodynamics. The thermodynamics e…
Magnon-polaron control in a surface magnetoacoustic wave resonator
Kevin Künstle, Yannik Kunz, Tarek Moussa +6
Strong coupling between distinct quasiparticles in condensed matter systems gives rise to hybrid states with emergent properties. We demonstrate the hybridization of confined phono…
Squeezing and quantum control of antiferromagnetic magnon pseudospin
Anna-Luisa E. Römling, Johannes Feist, Francisco J. García-Vidal +1
Antiferromagnets have been shown to harbor strong magnon squeezing in equilibrium, making them a potential resource for quantum correlations and entanglement. Recent experiments ha…
Exploring the Alignment of Perceived and Measured Sleep Quality with Working Memory using Consumer Wearables
Peter Neigel, David Antony Selby, Shota Arai +5
Wearable devices offer detailed sleep-tracking data. However, whether this information enhances our understanding of sleep or simply quantifies already-known patterns remains uncle…
