Integrable spin chains in twisted maximally supersymmetric Yang-Mills theory
We study an angular dipole deformation of maximally supersymmetric Yang-Mills theory (SYM) that preserves its classical scale invariance. We show that two-point functions of suitable single trace operators, restricted to an invariant plane, are determined by scaling dimensions computable from an integrable spin chain. This spin chain is a diagonally twisted version of the famous integrable spin chain of SYM. It matches expectations from the dual string theory perfectly, presenting a precision t…

Disorder-induced proximate quantum spin ice phase in Pr$_2$Sn$_2$O$_7$
We report a comprehensive bulk characterization and neutron scattering investigation of single-crystalline Pr$_2$Sn$_2$O$_7$, a magnetic pyrochlore synthesized via a flux-growth method. Unpolarized neutron diffuse scattering reveals the emergence of spin-ice correlations below $T \sim 1$ K, evidenced by the development of anisotropic pinch-point features that are consistent with quantum-spin-ice (QSI) behavior. A.C. susceptibility measurements indicate a progressive slowing of spin dynamics in …

Ranghoher russischer General schwer verletzt
Der Vizekommandeur des sogenannten Leningrader Wehrbezirks, Generalleutnant Esedulla Abatschew, ist nach russischen wie ukrainischen Angaben schwer verwundet worden. Abatschew sei seit den ersten Kriegstagen an der Front, schrieb das Oberhaupt der russischen Teilrepublik Dagestan, Sergej Melikow, auf Telegram. Abatschew, der aus Dagestan stammt, habe "mehrere wichtige Kommandeurspo…

Scaling behaviour of charged particles generated in Xe$-$Xe collisions at $\sqrt{s_{\rm{NN}}}$ = 5.44 TeV using the AMPT model
The spatial configurations of particles produced in the kinematic phase space during a heavy-ion collision reflect the characteristics of the system created in the collision. The scaling behaviour of the multiplicity fluctuations is studied for the charged particles generated in Xe--Xe collisions at $\sqrt{s_{\rm{NN}}}$ = 5.44 TeV using the String Melting (SM) mode of the AMPT (A Multi-Phase Transport) model. The scaling behaviour of the normalized factorial moments ($F_\text{q}$) give signific…

PGT-I: Scaling Spatiotemporal GNNs with Memory-Efficient Distributed Training
Spatiotemporal graph neural networks (ST-GNNs) are powerful tools for modeling spatial and temporal data dependencies. However, their applications have been limited primarily to small-scale datasets because of memory constraints. While distributed training offers a solution, current frameworks lack support for spatiotemporal models and overlook the properties of spatiotemporal data. Informed by a scaling study on a large-scale workload, we present PyTorch Geometric Temporal Index (PGT-I), an ex…

A Charge Constraint in BMN
I derive a new charge constraint that ties the four angular momenta in a $\frac{1}{16}$-BPS sector of the Berenstein, Maldacena, and Nastase (BMN) supersymmetric $U(N)$ matrix quantum mechanics. The result is related to the charge constraint of the $U(N)$, $\mathcal{N}=4$ Super-Yang-Mills (SYM) conformal field theory by identifying three SYM charges with three BMN angular momenta generating $SO(6)$, two equal SYM angular momenta with a BMN angular momentum of $SO(3)$, and scaling $N^2$ by $3$. …
