A simple, narrow, and robust atomic frequency reference at 993 nm exploiting the rubidium (Rb) to transition using one-color two-photon excitation
Thomas Nieddu, Tridib Ray, Krishnapriya S. Rajasree +2
We experimentally demonstrate a one-color two-photon transition from the ground state to the excited state in rubidium (Rb) vapor using a co…
Zero-phonon lines in the spectra of dysprosium atoms in superfluid helium
P. Moroshkin, K. Kono
We present an experimental study of a zero-phonon line (ZPL) in the absorption spectrum of Dy atoms solvated in superfluid He. The dopants reside in nanometer-sized spherical cavit…
Chaotic few-body vortex dynamics in rotating Bose--Einstein condensates
Tiantian Zhang, James Schloss, Andreas Thomasen +3
We investigate a small vortex-lattice system of four co-rotating vortices in an atomic Bose--Einstein condensate and find that the vortex dynamics display chaotic behaviour after a…
Statistical properties of worm algorithms for two dimensional frustrated Ising models
Geet Rakala, Kedar Damle, Deepak Dhar
We study the distribution of lengths and other statistical properties of worms constructed by Monte Carlo worm algorithms in the power-law three-sublattice ordered phase of frustra…
Negative thermal expansion in the plateau state of a magnetically-frustrated spinel
L. Rossi, A. Bobel, S. Wiedmann +6
We report on negative thermal expansion (NTE) in the high-field, half-magnetization plateau phase of the frustrated magnetic insulator CdCr2O4. Using dilatometry, we precisely map…
Linear magnetoresistance in the low-field limit in density-wave materials
Yejun Feng, Yishu Wang, D. M. Silevitch +9
The magnetoresistance (MR) of a material is typically insensitive to reversing the applied field direction and varies quadratically with magnetic field in the low-field limit. Quan…
Quench Dynamics and Orthogonality Catastrophe of Bose Polarons
S. I. Mistakidis, G. C. Katsimiga, G. M. Koutentakis +2
We monitor the correlated quench induced dynamical dressing of a spinor impurity repulsively interacting with a Bose-Einstein condensate. Inspecting the temporal evolution of the s…
Conformal Bootstrap Analysis for Localization: Symplectic Case
Shinobu Hikami
The localization phenomena due to the random potential scattering is widely discussed in the electron and photon systems, where the theoretical approach is the nonlinear model…
High-field Magnetism of the Honeycomb-lattice Antiferromagnet Cu(pymca)(ClO)
Akira Okutani, Takanori Kida, Yasuo Narumi +6
We report on the experimental results of magnetic susceptibility, specific heat, electron spin resonance (ESR), and high-field magnetization measurements on a polycrystalline sampl…
Optimal conditions for spatial adiabatic passage of a Bose-Einstein condensate
Juan Luis Rubio, Verònica Ahufinger, Thomas Busch +1
We investigate spatial adiabatic passage of a Bose-Einstein condensate in a triple well potential within the three-mode approximation. By rewriting the dynamics in the so-called ti…
Free surface flows using inverse smoothed particle hydrodynamics
Kalale Chola
Free surface flow problems including mixing processes in dam break flows and wave breaking phenomena are characterized by large deformation of the free surface. As such, they canno…
Thermodynamics and Feature Extraction by Machine Learning
Shotaro Shiba Funai, Dimitrios Giataganas
Machine learning methods are powerful in distinguishing different phases of matter in an automated way and provide a new perspective on the study of physical phenomena. We train a…
Spontaneous emission of a sodium Rydberg atom close to an optical nanofibre
E Stourm, Y Zhang, M Lepers +5
We report on numerical calculations of the spontaneous emission rate of a Rydberg-excited sodium atom in the vicinity of an optical nanofibre. In particular, we study how this rate…
Disorder induced power-law gaps in an insulator-metal Mott transition
Zhenyu Wang, Yoshinori Okada, Jared O'Neal +11
A correlated material in the vicinity of an insulator-metal transition (IMT) exhibits rich phenomenology and variety of interesting phases. A common avenue to induce IMTs in Mott i…
Gain lifetime characterization through time-resolved stimulated emission in a whispering-gallery mode microresonator
Xiao-Fei Liu, Fuchuan Lei, Tie-Jun Wang +2
The precise measurement of the gain lifetime at a specific wavelength holds significant importance for understanding the properties of photonic devices and further improving their…
Bet-hedging strategies in expanding populations
Paula Villa Martín, Miguel A. Muñoz, Simone Pigolotti
In ecology, species can mitigate their extinction risks in uncertain environments by diversifying individual phenotypes. This observation is quantified by the theory of bet-hedging…
Secondary flows of viscoelastic fluids in serpentine microchannels
Lucie Ducloue, Laura Casanellas, Simon J. Haward +5
Secondary flows are ubiquitous in channel flows, where small velocity components perpendicular to the main velocity appear due to the complexity of the channel geometry and/or that…
Coherent Impurity Transport in an Attractive Binary Bose-Einstein condensate
M. J. Edmonds, J. L. Helm, Th. Busch
We study the dynamics of a soliton-impurity system modeled in terms of a binary Bose-Einstein condensate. This is achieved by `switching off' one of the two self-interaction scatte…
How to switch between relational quantum clocks
Philipp A Hoehn, Augustin Vanrietvelde
Every clock is a physical system and thereby ultimately quantum. A naturally arising question is how to describe time evolution relative to quantum clocks and, specifically, how th…
Ripple state in the frustrated honeycomb-lattice antiferromagnet
Tokuro Shimokawa, Hikaru Kawamura
We discover a new type of multiple- state, "ripple state", in a frustrated honeycomb-lattice Heisenberg antiferromagnet under magnetic fields. The ground state has an infinite r…
Detection of polarized gamma-ray emission from the Crab nebula with Hitomi Soft Gamma-ray Detector
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +191
We present the results from the Hitomi Soft Gamma-ray Detector (SGD) observation of the Crab nebula. The main part of SGD is a Compton camera, which in addition to being a spectrom…
