Approaching the quantum critical point in a highly-correlated all-in-all-out antiferromagnet
Yishu Wang, T. F. Rosenbaum, D. Prabhakaran +2
Continuous quantum phase transitions involving all-in-all-out (AIAO) antiferromagnetic order in strongly spin-orbit-coupled 5d compounds could give rise to various exotic electroni…
Variational Recurrent Models for Solving Partially Observable Control Tasks
Dongqi Han, Kenji Doya, Jun Tani
In partially observable (PO) environments, deep reinforcement learning (RL) agents often suffer from unsatisfactory performance, since two problems need to be tackled together: how…
Thermalization of photoexcited carriers in two-dimensional transition metal dichalcogenides and internal quantum efficiency of van der Waals heterostructures
Dinesh Yadav, Maxim Trushin, Fabian Pauly
Van der Waals semiconductor heterostructures could be a platform to harness hot photoexcited carriers in the next generation of optoelectronic and photovoltaic devices. The interna…
Probabilistic motional averaging
D. S. Karpov, V. Y. Monarkha, D. Szombati +6
In a continuous measurement scheme a spin-1/2 particle can be measured and simultaneously driven by an external resonant signal. When the driving is weak, it does not prevent the p…
Dynamical Coulomb Blockade as a Local Probe for Quantum Transport
Jacob Senkpiel, Jan C. Klöckner, Markus Etzkorn +9
Quantum fluctuations are imprinted with valuable information about transport processes. Experimental access to this information is possible, but challenging. We introduce the dynam…
Search for an invisibly decaying boson at Belle II in plus missing energy final states
Belle II Collaboration, I. Adachi, P. Ahlburg +358
Theories beyond the standard model often predict the existence of an additional neutral boson, the . Using data collected by the Belle II experiment during 2018 at the…
Examining the surface phase diagram of IrTe with photoemission
M. Rumo, C. W. Nicholson, A. Pulkkinen +13
In the transition metal dichalcogenide IrTe, low-temperature charge-ordered phase transitions involving Ir dimers lead to the occurrence of stripe phases of different periodici…
Lightcone expansions of conformal blocks in closed form
Wenliang Li
We present new closed-form expressions for 4-point scalar conformal blocks in the s- and t-channel lightcone expansions. Our formulae apply to intermediate operators of arbitrary s…
High Scale Validity of the DFSZ Axion Model with Precision
Satsuki Oda, Yutaro Shoji, Dai-suke Takahashi
With the assumption of classical scale invariance at the Planck scale, the DFSZ axion model can generate the Higgs mass terms of the appropriate size through technically natural pa…
The Trinity of Relational Quantum Dynamics
Philipp A. Hoehn, Alexander R. H. Smith, Maximilian P. E. Lock
The problem of time in quantum gravity calls for a relational solution. Using quantum reduction maps, we establish a previously unknown equivalence between three approaches to rela…
Exact results for persistent currents of two bosons in a ring lattice
Juan Polo, Piero Naldesi, Anna Minguzzi +1
We study the ground state of two interacting bosonic particles confined in a ring-shaped lattice potential and subjected to a synthetic magnetic flux. The system is described by th…
On-surface synthesis of polyazulene with 2,6-connectivity
Qiang Sun, Ian Cheng-Yi Hou, Kristjan Eimre +4
Azulene, the smallest neutral nonalternant aromatic hydrocarbon, serves as not only a prototype for fundamental studies but also a versatile building block for functional materials…
Geodesic string condensation from symmetric tensor gauge theory: a unifying framework of holographic toy models
Han Yan
In this work we reason that there is a universal picture for several different holographic toy model constructions, and a gravity-like bulk field theory that gives rise it. First,…
Optimization and Validation of Diffusion MRI-based Fiber Tracking with Neural Tracer Data as a Reference
Carlos Enrique Gutierrez, Henrik Skibbe, Ken Nakae +11
Diffusion-weighted magnetic resonance imaging (dMRI) allows non-invasive investigation of whole-brain connectivity, which can potentially help to reveal the brain's global network…
Length scales in Brownian yet non-Gaussian dynamics
J. M. Miotto, S. Pigolotti, A. V. Chechkin +1
According to the classical theory of Brownian motion, the mean squared displacement of diffusing particles evolves linearly with time whereas the distribution of their displacement…
Observation of two-dimensional Anderson localisation of ultracold atoms
Donald H. White, Thomas A. Haase, Dylan J. Brown +6
Anderson localisation -- the inhibition of wave propagation in disordered media -- is a surprising interference phenomenon which is particularly intriguing in two-dimensional (2D)…
Many-body quantum dynamics and induced correlations of Bose polarons
S. I. Mistakidis, G. M. Koutentakis, G. C. Katsimiga +2
We study the ground state properties and nonequilibrium dynamics of two spinor bosonic impurities immersed in a one-dimensional bosonic gas upon applying an interspecies interactio…
A unified view of likelihood ratio and reparameterization gradients and an optimal importance sampling scheme
Paavo Parmas, Masashi Sugiyama
Reparameterization (RP) and likelihood ratio (LR) gradient estimators are used throughout machine and reinforcement learning; however, they are usually explained as simple mathemat…
Coupled density-spin Bose-Einstein condensates dynamics and collapse in systems with quintic nonlinearity
Jing Li, Boris A. Malomed, Wenliang Li +2
We investigate the effects of spin-orbit coupling and Zeeman splitting on the coupled density-spin dynamics and collapse of the Bose-Einstein condensate driven by the quintic self-…
