Deep learning of committor for ion dissociation and interpretable analysis of solvent effects using atom-centered symmetry functions
Kenji Okada, Kazushi Okada, Kei-ichi Okazaki +3
The association and dissociation of ion pairs in water are fundamental to physical chemistry, yet their reaction coordinates are complex, involving not only interionic distance but…
Determining the density of in-gap states in organic semiconductors: A pitfall of photoelectron yield spectroscopy
Ryotaro Nakazawa, Masaya Kitaoka, Ryota Kaimori +4
Accurate determination of low-density electronic states in the bandgap (in-gap states) is crucial for optimizing the performance of organic optoelectronic devices. Derivative photo…
Diffraction-Unlimited Tip-Enhanced Sum-Frequency Vibrational Nanoscopy
Shota Takahashi, Koichi Kumagai, Atsunori Sakurai +4
Sum-frequency generation (SFG) is a powerful second-order nonlinear spectroscopic technique that provides detailed insights into molecular structures and absolute orientations at s…
Giant near-field nonlinear electrophotonic effects in an angstrom-scale plasmonic junction
Shota Takahashi, Atsunori Sakurai, Tatsuto Mochizuki +1
Plasmons facilitate a strong confinement and enhancement of near-field light, offering exciting opportunities to enhance nonlinear optical responses at the nanoscale. However, desp…
Dramatic Enhancement of Supercontinuum Generation in HO by Non-Harmonic Two-Color Excitation
Tsuneto Kanai, ChengXiang Jin, Hibiki Tsunekawa +2
We demonstrate a dramatic enhancement of supercontinuum generation (SCG) in HO driven by non-harmonic two-color laser fields, where pump and seed frequencies are not integer mu…
Probing spin-motion coupling of two Rydberg atoms by a Stern-Gerlach-like experiment
Gabriel Emperauger, Mu Qiao, Guillaume Bornet +7
We propose and implement a protocol to measure the state-dependent motion of Rydberg atoms induced by dipole-dipole interactions. Our setup enables simultaneous readout of both the…
Proposal for realizing Heisenberg-type quantum-spin models in Rydberg-atom quantum simulators
Masaya Kunimi, Takafumi Tomita
We investigate the magnetic-field dependence of the interaction between two Rydberg atoms, and . In this setting, the effective s…
Fragility of Topology under Electronic Correlations in Iron Chalcogenides
Younsik Kim, Junseo Yoo, Sehoon Kim +5
The interplay between electronic correlations and topology is a central topic in the study of quantum materials. In this work, we investigate the impact of the orbital-selective Mo…
Dissipation Pathways in a Photosynthetic Complex
Ignacio Gustin, Chang Woo Kim, Ignacio Franco
Determining how energy flows within and between molecules is crucial for understanding chemical reactions, material properties, and even vital processes such as photosynthesis. Whi…
Direct observation of long-range many-body coherence in quasi-one-dimensional attractive Bose gases
Hikaru Tamura, Sambit Banerjee, Rongjie Li +3
Macroscopic coherence is an important feature of quantum many-body systems exhibiting collective behaviors, with examples ranging from atomic Bose-Einstein condensates, and quantum…
Generation of Motional Squeezed States for Neutral Atoms in Optical Tweezers
Vincent Lienhard, Romain Martin, Yuki Torii Chew +3
Optical tweezers are a powerful tool for the precise positioning of a variety of small objects, including single neutral atoms. Once trapped, atoms can be cooled to the motional gr…
Evidence for energy-dependent scattering dominating thermoelectricity in heavy fermion systems
Daiki Goto, Kentaro Kuga, Kiyohisa Tanaka +2
In the field of thermoelectric materials and devices, improving energy conversion efficiency remains a long-standing challenge. As a promising approach to address this issue, utili…
Raman Optical Activity Induced by Ferroaxial Order in NiTiO
Gakuto Kusuno, Takeshi Hayashida, Takayuki Nagai +4
Raman optical activity (ROA), the dependence of Raman intensity on the circular polarization of incident and scattered light, has traditionally been observed in chiral molecules an…
Systematic construction of asymptotic quantum many-body scar states and their relation to supersymmetric quantum mechanics
Masaya Kunimi, Yusuke Kato, Hosho Katsura
We develop a systematic method for constructing asymptotic quantum many-body scar (AQMBS) states. While AQMBS states are closely related to quantum many-body scar (QMBS) states, th…
Kinetic phase diagram for two-step nucleation in colloid-polymer mixtures
Willem Gispen, Peter G. Bolhuis, Marjolein Dijkstra
Two-step crystallization via a metastable intermediate phase is often regarded as a non-classical process that lies beyond the framework of classical nucleation theory (CNT). In th…
Electron-Chiral Phonon Coupling, Crystal Angular Momentum, and Phonon Chirality
Tomomi Tateishi, Akihito Kato, Jun-ichiro Kishine
We explicitly derive the wavefunctions of chiral phonons propagating along the helical axis in chiral crystals and clarify the characteristics of electron-phonon interactions in ch…
