Observing Magnetic Monopoles in Spin Ice using Electron Holography
Ankur Dhar, Ludovic D. C. Jaubert, Cathal Cassidy +2
While there is compelling evidence for the existence of magnetic monopoles in spin ice, the direct observation of a point-like source of magnetic field in these systems remains an…
Antagonistic interactions can stabilise fixed points in heterogeneous linear dynamical systems
Samuel Cure, Izaak Neri
We analyse the stability of large, linear dynamical systems of variables that interact through a fully connected random matrix and have inhomogeneous growth rates. We show that in…
Schurian-finiteness of blocks of type Hecke algebras
Susumu Ariki, Sinéad Lyle, Liron Speyer
For any algebra over an algebraically closed field , we say that an -module is Schurian if . We say that is Schurian-…
Bloch oscillations in supersolids
Muhammad S. Hasan, J. Polo, J. C. Pelayo +1
We show that the motion of an accelerated atomic impurity immersed in a spin-orbit coupled Bose-Einstein condensate in the supersolid stripe phase undergoes oscillations, similar t…
Feature extraction of machine learning and phase transition point of Ising model
Shotaro Shiba Funai
We study the features extracted by the Restricted Boltzmann Machine (RBM) when it is trained with spin configurations of Ising model at various temperatures. Using the trained RBM,…
Punctures and p-spin curves from matrix models III. Dl type and logarithmic potential
Shinobu Hikami
The intersection numbers for p spin curves of the moduli space M(g,n) are considered for D type by a matrix model. The asymptotic behavior of the large genus g limit and large p li…
Squeezing by Critical Speeding-up: Applications in Quantum Metrology
Karol Gietka
We present an alternative protocol allowing for the preparation of critical states that instead of suffering from the critical slowing-down benefits from the critical speeding-up.…
Partonic behavior of string scattering amplitudes from holographic QCD models
Massimo Bianchi, Maurizio Firrotta, Jacob Sonnenschein +1
We study the emergence of partonic behavior in scattering processes at large Mandelstam's variable from string amplitudes in holographic backgrounds. We generalize the approach…
On the fully coupled dynamics of flexible fibres dispersed in modulated turbulence
Stefano Olivieri, Andrea Mazzino, Marco E. Rosti
The present work investigates the mechanical behaviour of finite-size, elastic and inertial fibres freely moving in a homogeneous and isotropic turbulent flow at moderate Reynolds…
Compact Object Mergers in Hierarchical Triples from Low-Mass Young Star Clusters
Alessandro Alberto Trani, Sara Rastello, Ugo N. Di Carlo +3
A binary star orbited by an outer companion constitutes a hierarchical triple system. The outer body may excite the eccentricity of the inner binary through the von~Zeipel-Lidov-Ko…
Asymptotic freedom and safety in quantum gravity
Saswato Sen, Christof Wetterich, Masatoshi Yamada
We compute non-perturbative flow equations for the couplings of quantum gravity in fourth order of a derivative expansion. The gauge invariant functional flow equation for arbitrar…
A Rindler Road to Carrollian Worldsheets
Arjun Bagchi, Aritra Banerjee, Shankhadeep Chakrabortty +1
The tensionless limit of string theory has recently been formulated in terms of worldsheet Rindler physics. In this paper, by considering closed strings moving in background Rindle…
Perspective-neutral approach to quantum frame covariance for general symmetry groups
Anne-Catherine de la Hamette, Thomas D. Galley, Philipp A. Hoehn +2
In the absence of external relata, internal quantum reference frames (QRFs) appear widely in the literature on quantum gravity, gauge theories and quantum foundations. Here, we ext…
Magnetic order, disorder, and excitations under pressure in the Mott insulator SrIrO
Xiang Li, S. E. Cooper, A. Krishnadas +7
Protected by the interplay of on-site Coulomb interactions and spin-orbit coupling, SrIrO at high pressure is a rare example of a Mott insulator with a paramagnetic ground…
Repulsive Casimir-Polder potentials of low-lying excited states of a multilevel alkali-metal atom near an optical nanofiber
Fam Le Kien, D. F. Kornovan, Sile Nic Chormaic +1
We study the Casimir-Polder potential of a multilevel alkali-metal atom near an optical nanofiber. We calculate the mean potential of the atom in a fine-structure level. We perform…
Inverted harmonic oscillator dynamics of the nonequilibrium phase transition in the Dicke model
Karol Gietka, Thomas Busch
We show how the dynamics of the Dicke model after a quench from the ground-state configuration of the normal phase into the superradiant phase can be described for a limited time b…
Machine learner optimization of optical nanofiber-based dipole traps for cold Rb atoms
Ratnesh K. Gupta, Jesse L. Everett, Aaron D. Tranter +4
In two-color optical nanofiber-based dipole traps for cold alkali atoms, the trap efficiency depends on the wavelength and intensity of light in the evanescent field, and the initi…
Dominating Interlayer Resonant Energy Transfer in Type-II 2D Heterostructure
Arka Karmakar, Abdullah Al-Mahboob, Christopher E. Petoukhoff +5
Type-II heterostructures (HSs) are essential components of modern electronic and optoelectronic devices. Earlier studies have found that in type-II transition metal dichalcogenide…
Merger rate density of binary black holes through isolated Population I, II, III and extremely metal-poor binary star evolution
Ataru Tanikawa, Takashi Yoshida, Tomoya Kinugawa +4
We investigate the formation of merging binary black holes (BHs) through isolated binary evolution, performing binary population synthesis calculations covering an unprecedentedly…
Understanding and Improving Critical Metrology. Quenching Superradiant Light-Matter Systems Beyond the Critical Point
Karol Gietka, Lewis Ruks, Thomas Busch
We carefully examine critical metrology and present an improved critical quantum metrology protocol which relies on quenching a system exhibiting a superradiant quantum phase trans…
