Tip-Enhanced Sum Frequency Generation for Molecular Vibrational Nanospectroscopy
Atsunori Sakurai, Shota Takahashi, Tatsuto Mochizuki +1
Vibrational sum frequency generation (SFG) is a nonlinear spectroscopic technique widely used to study the molecular structure and dynamics of surface systems. However, the spatial…
Magnetic resonance frequency of two-sublattice ferrimagnet with magnetic compensation temperature
Kouki Mikuni, Toshiki Hiraoka, Takumi Kuramoto +5
Ferrimagnetic materials with a compensation temperature have recently attracted interest because of their unique combination of ferromagnetic and antiferromagnetic properties. Howe…
Resonant stroboscopic Rydberg dressing: electron-motion coupling and multi-body interactions
Chris Nill, Sylvain de Léséleuc, Christian Groß +1
Rydberg dressing traditionally refers to a technique where interactions between cold atoms are imprinted through the far off-resonant continuous-wave excitation of high-lying Rydbe…
Picocavity-Enhanced Raman Spectroscopy of Physisorbed H and D Molecules
Akitoshi Shiotari, Shuyi Liu, George Trenins +4
We report on tip-enhanced Raman spectroscopy of H2 and D2 molecules physisorbed within a plasmonic picocavity at 10 K. The intense Raman peaks resulting from the rotational and vib…
Measurement and feed-forward correction of the fast phase noise of lasers
Tom Denecker, Yukii Torii Chew, Oscar Guillemant +4
Lasers are the workhorse of quantum engineering in the atomic-molecular-optic community. However, phase noise of the laser, which can be especially large in popular semiconductor-b…
Optimization-based hologram design for fine optical tweezer arrays and extension of super-resolution criteria
Keisuke Nishimura, Hiroto Sakai, Takafumi Tomita +2
Aligning light spots into arbitrary shapes is a fundamental challenge in holography, leading to various applications across diverse fields in science and engineering. However, as t…
Transition Path and Interface Sampling of Stochastic Schrödinger Dynamics
Robson Christie, Peter G. Bolhuis, David T. Limmer
We study rare transitions in Markovian open quantum systems driven with Gaussian noise, applying transition path and interface sampling methods to trajectories generated by stochas…
Atom Camera: Super-resolution scanning microscope of a light pattern with a single ultracold atom
Takafumi Tomita, Yuki Torii Chew, Rene Villela +6
Sub-micrometer scale light patterns play a pivotal role in various fields, including biology, biophysics, and AMO physics. High-resolution, in situ observation of light profiles is…
Double Configuration Interaction Singles: Scalable and size-intensive approach for orbital relaxation in excited states and bond-dissociation
Takashi Tsuchimochi
We present a novel theoretical scheme for orbital relaxation in configuration interaction singles (CIS) based on a perturbative treatment of its electronic Hessian, whose analytica…
Photo-induced phase transition on black samarium monosulfide
Hiroshi Watanabe, Yusuke Takeno, Yusuke Negoro +14
To investigate the role of the excitons for the origin of the pressure-induced phase transition (BGT) from the black-colored insulator (BI) to the golden-yellow-colored metal (GM)…
Chirality-dependent spin polarization in metals: linear and quadratic responses
Kosuke Yoshimi, Yusuke Kato, Yuta Suzuki +6
We study spin polarization induced by locally injected electric currents in a metal whose spin--orbit coupling reflects its structural chirality. We reveal both spin polarization i…
Investigating the hyperparameter space of deep neural network models for reaction coordinates
Kyohei Kawashima, Takumi Sato, Kei-ichi Okazaki +3
Identifying reaction coordinates (RCs) is a key to understanding the mechanism of reactions in complex systems. Deep neural network (DNN) and machine learning approaches have becom…

Quantification of chirality based on electric toroidal monopole
Akane Inda, Rikuto Oiwa, Satoru Hayami +2
Chirality ubiquitously appears in nature, however, its quantification remains obscure owing to the lack of microscopic description at the quantum-mechanical level. We propose a way…
