From supernovae to neutron stars: crust formation time
Yudai Suwa, Ken'ichiro Nakazato
A neutron star is born as a hot, lepton-rich protoneutron star (PNS) and cools via neutrino emission, eventually allowing heavy ions in the outer layers to crystallize into a solid…
Constraining Spatial Curvature with Priors from Swampland Conjectures
Simran Arora, Hun Jang, Shinji Mukohyama
We study a string-motivated theoretical prior on the quintessential dark energy model with exponential potential, \( V(ϕ) = V_0 e^{-λϕ} \), allowing for non-zero spatial curvature.…
Observation of Restored Adiabatic State Transfer in Time-Modulated Non-Hermitian Systems
Xiaowei Wang, Ievgen I. Arkhipov, Quan Lin +5
Exceptional points (EPs) have attracted extensive research interest due to their intriguing properties. One of the hallmarks of EP physics is that dynamically encircling the EPs in…
Scaling Quantum Machine Learning without Tricks: Full-Resolution and Diverse Image Generation
Jonas Jäger, Florian J. Kiwit, Carlos A. Riofrío
Quantum generative modeling is a rapidly evolving discipline at the intersection of quantum computing and machine learning. Contemporary quantum machine learning is generally limit…
Light rings, gravitational lensing, and ISCOs of exotic compact objects in Einstein-scalar-Maxwell theories
Antonio De Felice, Shinji Tsujikawa
In Einstein-scalar-Maxwell theories with a coupling between the scalar field and the electromagnetic field strength of the form , we investigate the existence of ex…
Quantum feature-map learning with reduced resource overhead
Jonas Jäger, Philipp Elsässer, Elham Torabian
Current quantum computers require algorithms that use limited resources economically. In quantum machine learning, success hinges on quantum feature-maps, which embed classical dat…
Cavity QED based on strongly localized modes: exponentially enhancing single-atom cooperativity
Qian Bin, Ying Wu, Jin-Hua Gao +3
Large single-atom cooperativity in quantum systems is important for quantum information processing. Here, we propose to exponentially enhance the single-atom cooperativity paramete…
Signature of axion dark matter in low-frequency terrestrial electromagnetic fields: formulation and predictions
Atsushi Taruya, Atsushi Nishizawa, Yoshiaki Himemoto
We develop a theoretical framework for axion dark matter (DM) searches using terrestrial electromagnetic (EM) fields, enabling a global and quantitative characterization of the sig…
Quantum geometric bounds for observables: Linear responses, Drude weight, and orbital magnetization
Koki Shinada, Naoto Nagaosa
The quantum geometric tensor (QGT) provides nontrivial bounds among physical quantities, as exemplified by the metric-curvature inequality. In this paper, we investigate various bo…
Accelerating Universe from Constraints
Anamaria Hell, Misao Sasaki
We introduce a framework of constrained scalar fields that can give rise to cosmological evolution of the Universe independent of the values of the cosmological constant. Focusing…
Nanosculpted 3D helices of a magnetic Weyl semimetal with switchable nonreciprocity
Max T. Birch, Yukako Fujishiro, Ilya Belopolski +6
The emergent properties of materials are defined by the symmetries of their underlying atomic, spin and charge order. The explorations of symmetry breaking effects are therefore us…
Probing the Dynamics of Gaussian Dark Energy Equation of State Using DESI BAO
Saddam Hussain, Simran Arora, Anzhong Wang +1
We present an updated reconstruction of the DE equation of state (EoS), , employing the newly released DESI DR2 Baryon Acoustic Oscillation data. This analysis constrains the…
Measuring the asymmetric expansion of the Fe ejecta of Cassiopeia A with XRISM/Resolve
Aya Bamba, Manan Agarwal, Jacco Vink +24
The expansion structure of supernova remnants (SNRs) is important for understanding not only how heavy elements are distributed into space, but also how supernovae explode. The eje…
Energy-Momentum Tensor and D-term of Baryons in Top-down Holographic QCD
Shigeki Sugimoto, Taichi Tsukamoto
We study the energy-momentum tensor of a baryon in a top-down holographic QCD. In holographic QCD, the baryons are represented as solitons in a 5-dimensional gauge theory. We obtai…
Macroscopic Particle Transport in Dissipative Long-Range Bosonic Systems
Hongchao Li, Cheng Shang, Tomotaka Kuwahara +1
Dissipation in quantum many-body systems provides a more general and experimentally realistic perspective on particle transport than closed quantum systems. In this work, we determ…
Diffusion Transients in Motility-Induced Phase Separation
Shubhadip Nayak, Poulami Bag, Pulak K. Ghosh +4
We numerically investigate normal diffusion in a two-dimensional athermal suspension of active particles undergoing motility-induced phase separation. The particles are modeled as…
Nonreciprocal transport in a room-temperature chiral magnet
Daisuke Nakamura, Mu-Kun Lee, Kosuke Karube +4
Chiral magnets under broken time-reversal symmetry can give rise to rectification of moving electrons, called nonreciprocal transport. Several mechanisms, such as the spin-fluctuat…
