Detecting (emergent) continuous symmetry of criticality via subsystem's entanglement spectrum
The (emergent) symmetry of a critical point is one of the most important information to identify the universality class and effective field theory, which is fundamental for various critical theories. However, the underlying symmetry so far can only be conjectured indirectly from the dimension of the order parameters in symmetry-breaking phases, and its correctness requires further verifications to avoid overlooking hidden order parameters, which by itself is also a difficult task. In this work,…

SmartAttack: Air-Gap Attack via Smartwatches
Air-gapped systems are considered highly secure against data leaks due to their physical isolation from external networks. Despite this protection, ultrasonic communication has been demonstrated as an effective method for exfiltrating data from such systems. While smartphones have been extensively studied in the context of ultrasonic covert channels, smartwatches remain an underexplored yet effective attack vector. In this paper, we propose and evaluate SmartAttack, a novel method that levera…

Effect of non-conformal deformation on the gapped quasinormal modes and its holographic implications
The spectral curve of quasinormal modes for a massive real scalar field in the background of a non-conformal black brane geometry has been obtained by utilizing a Frobenius type near-horizon expansion. The gauge/gravity duality maps this to the computation of spectral curve of a scalar operator $\mathcal{O}_ϕ$ with conformal dimension $Δ_ϕ$ for a large-$N$ conformal field theory with irrelevant type non-conformal deformation. In this context, non-conformality has been holographically introdu…

Low-Cost Wideband Tilted Beam Antenna for Millimeter-wave Vehicle Applications
To facilitate vehicle coverage for millimeter-wave applications, this communication presents a low-cost, wideband tilted-beam antenna. A novel design is proposed in which a slot antenna is both directly excited and electromagnetically coupled to a monopole array. This slot-monopole configuration is inherently robust against substrate losses, enabling low-cost fabrication while maintaining high realized gain and compact size. Furthermore, the slot-fed structure effectively excites multiple reson…

The only jury I've ever been on faced a question about resisting arrest. The defendant was tackled by an officer and initially fought back (or so the officer claimed). The officer was wearing a police uniform, but we acquitted on the charge, because the defendant was tackled from behind and there was reasonable doubt as to whether the officer actually identified themselves verbally in a way that made it clear to the defendant they weren't being tackled by some random dude.
This ain't legal advice, but in situations where a kidnapper refuses to identify themselves, show a warrant, or even a badge number, I suspect a sufficiently white bystander might not be convicted on interference charges if they did something like a citizen's arrest of a suspicious out-of-town paramilitary type who was in the process of an extrajudicial kidnapping. If there are multiple kidnappers, to be effective you might need multiple people willing to face jail time for such interventions to be successful...
#resist #ICE #kidnapping
Just thinking about this in light of the recent kidnapping in the next town over where some fools called the city police thinking they might actually protect the community from an unlawful assault. Can't blame the fools too much because of how deep positive portrayals of cops are embedded in our media diet though...

Radiative decay of $χ_{c1}$ states in effective Lagrangian approach
The $χ_{c1}(3872)$ state, first observed by the Belle collaboration with its quantum numbers identified as $J^{PC} = 1^{++}$, has been the subject of extensive research due to its intriguing properties. Several theoretical interpretations have been proposed to explain its unique characteristics, including the $χ_{c1}(2P)$ assignment, a molecular $\bar{D}^{*}D/\bar{D}D^{*}$ configuration, a coupled-channel framework incorporating $c\bar{c}$ and di-meson degrees of freedom, and the compact tetr…

Simplifying explicit subtyping coercions in a polymorphic calculus with effects
Algebraic effect handlers are becoming an increasingly popular way of structuring effectful computations, and their performance is often a concern. One of the proposed approaches towards efficient compilation is tracking effect information through explicit subtyping coercions. However, in the presence of polymorphism, these coercions are compiled into additional arguments of compiled functions, incurring significant overhead. In this paper, we present a polymorphic effectful calculus, identify …

Generic Chiral Anomaly and Planar Hall Effect in a Non-Weyl System
The condensed-matter version of the chiral anomaly describes how electrons are pumped from a Weyl node with negative chirality to a Weyl node with positive chirality using parallel electric and magnetic fields. Key experimental signatures are a negative longitudinal magnetoresistance (LMR) and the planar Hall effect (PHE), both of which have been experimentally observed. Here, we show that the chiral anomaly explains key features of magnetotransport in the nodal-line semimetal ZrTe$_5$ despite …

Unveiling the role of vector potential in the Aharonov-Bohm effect
The most popular interpretation of the Aharonov-Bohm (AB) effect is that the electromagnetic potential locally affects the complex phase of a charged particle's wave function in the magnetic field free region. However, since the vector potential is a gauge-variant quantity, not a few researchers suspect that it is just a convenient tool for calculating the force field. This motivates them to explain the AB effect without using the vector potential, which inevitably leads to some sort of non-loc…
