The degrees of freedom of multiway junctions in three dimensional gravity
We demonstrate that $n$-way junctions in three dimensional gravity correspond to coupled $n-1$ strings each satisfying the Nambu-Goto equation in the smoothened background, and with sources consisting of Monge-Ampère like terms which couple the strings. For $n\geq 3$, these $n-1$ degrees of freedom survive the tensionless limit implying that matter-like behavior can arise out of $pure$ gravity. We interpret these stringy degrees of freedom of gravitational junctions holographically in terms of…

Magnetization by Rotation: Spin and Chiral Condensates in the NJL Model
The role of spin degrees of freedom in the quark-gluon plasma (QGP) has attracted significant interest in recent years. Spin hydrodynamics extends conventional hydrodynamics by incorporating spin via the spin tensor. In the mean-field limit of the Nambu-Jona-Lasinio (NJL) model under rigid rotation, spin degrees of freedom manifest naturally as axial-vector, or spin, condensate. We investigate the interplay between chiral and spin condensates in this framework. While rotation typically suppress…

Rafael Viñoly will forever be remembered as the guy who designed two buildings, one in Las Vegas and the other in London, that use a special shape that turns sunlight into a death ray. When confronted about this by The Guardian, he gave the best interview possible:
“I knew this was going to happen [...] When it was spotted on a second design iteration, we judged the temperature was going to be about 36 degrees, but it's turned out to be more like 72 degrees. They are callin…

The Hiraga-Ichino-Ikeda conjecture on formal degrees for classical groups
We prove a conjecture of Hiraga-Ichino-Ikeda relating formal degrees of square-integrable representations to adjoint gamma factors for symplectic and even orthogonal groups over characteristic zero non-Archimedean local fields. The proof is based on the twisted endoscopic characterization of the local Langlands correspondence for such groups and extends an approach already appearing in the original paper of Hiraga-Ichino-Ikeda itself inspired from earlier work of Shahidi. Namely, the argument c…

FAS-ARIS: Turning Multipath Challenges Into Localization Opportunities
Traditional single-input single-output (SISO) systems face fundamental limitations in achieving accurate three-dimensional (3D) localization due to limited spatial degrees of freedom (DoF) and the adverse impact of multipath propagation. This paper proposes a novel fluid antenna system (FAS)-active reconfigurable intelligent surface (ARIS) framework that transforms multipath effects from a hindrance into a resource for enhanced localization. By synergistically combining the signal amplification…

Thermal Cycling Reliability of Hybrid Pixel Sensor Modules for The ATLAS High Granularity Timing Detector
The reliability of bump connection structures has become a critical aspect of future silicon detectors for particle physics. The High Granularity Timing Detector (HGTD) for the ATLAS experiment at the High-Luminosity Large Hadron Collider will require 8032 hybrid pixel sensor modules, composed of two Low Gain Avalanche Diode sensors bump-bonded to two readout ASICs and glued to a passive PCB. The detector will operate at low temperature (-30 degrees Celsius) to mitigate the impact of irradiatio…

Ramsey Interferometry with Qudits
Ramsey interferometry, a cornerstone technique in quantum spectroscopy, traditionally operates with qubits for high precision measurements. In this work we build on Ramsey interferometry, extending it to qudits in Wigner-Majorana (WM) systems where the internal degrees of freedom are used to achieve enhanced resolution. We also show that replacing the two $π/2$ pulses of standard Ramsey interferometry with the quantum Fourier transform provides no increase in resolution. Theoretical analysis f…

Explicit Stillman bounds for all degrees
In 2016 Ananyan and Hochster proved Stillman's conjecture by showing the existence of a uniform upper bound on the lengths of an $R_η$-sequence containing a fixed $n$ forms of degree at most $d$ in polynomial rings over a field. This result yields many other uniform bounds including bounds on the projective dimension of the ideals generated by $n$-forms of degree at most $d$. Explicit values of these bounds for forms of degrees $5$ and higher are not yet known. This article constructs such e…

Found my use. I am a water fountain for butterflies. Was cutting the grass today and took a short break under a tree . It's hot 97 degrees and the wife says the feels like was 113 degrees. If so that is crazy hot.
I was covered with sweat and a butterfly landed on my arm. It stayed there so I lifted my arm to look and it was drinking my sweat. Next thing I know 2 more appear and land. I let them drink and before anymore could do the same moved on as I wanted to finish the yard n…

Asymptotic enumeration of graph factors by cumulant expansion
Let $G$ be a dense graph with good expansion properties and not too close to being bipartite. Let $\boldsymbol d$ be a graphical degree sequence. Under very weak conditions, we find the number of subgraphs of $G$ with degree sequence $\boldsymbol d$ to arbitrary precision. The average degree can be any power of $n$ and the variation in degrees can be very large. The method uses an explicit bound on the tail of the cumulant generating function found by the first author. As a first application, w…
