On a long exact sequence of groups of equivalence classes of 2d $mathcalN=(0,1)$ SQFTs

Posted by klaurent Tokyo

Kavli Affiliate: Yuji Tachikawa | Summary:Strongly motivated by a mathematical result by Lin and Yamashita (arXiv:2412.02298), we describe a long exact sequence formed by groups of equivalence classes of two-dimensional $mathcalN=(0,1)$ supersymmetric quantum field theories (SQFTs) with and without $SU(2)$ symmetry. As an application, we study chiral fermions in heterotic compactifications with $SU(2)$ symmetry of […]

Predicting stellar collision outcomes of main sequence stars

Posted by klaurent Peking

Kavli Affiliate: Pau Amaro Seoane | Summary:Stellar collisions in dense galactic nuclei might play an important role in fueling supermassive black holes (SMBHs) and shaping their environments. The gas released during these collisions can contribute to SMBH accretion, influencing phenomena such as active galactic nuclei and tidal disruption events of the remnants. We address the […]

Determination of the fifth Busy Beaver value

Posted by klaurent Cornell

Kavli Affiliate: Chris Xu | First 5 Authors: The bbchallenge Collaboration, The bbchallenge Collaboration, , , | Summary: We prove that $S(5) = 47,176,870$ using the Coq proof assistant. The Busy Beaver value $S(n)$ is the maximum number of steps that an $n$-state 2-symbol Turing machine can perform from the all-zero tape before halting, and […]

Accurate ground states of $SU(2)$ lattice gauge theory in 2+1D and 3+1D

Posted by klaurent Delft

Kavli Affiliate: Eliska Greplova | Summary:We present a neural network wavefunction framework for solving non-Abelian lattice gauge theories in a continuous group representation. Using a combination of $SU(2)$ equivariant neural networks alongside an $SU(2)$ invariant, physics-inspired ansatz, we learn a parameterization of the ground state wavefunction of $SU(2)$ lattice gauge theory in 2+1 and 3+1 […]

Origin of the double-peaked narrow emission-lines in the optical spectra of X-shaped Radio Galaxies

Posted by klaurent Peking

Kavli Affiliate: Luis Ho | Summary:We investigate X-shaped radio galaxies (XRGs) with optical double-peaked narrow emission lines (DPNELs) as potential hosts of dual or binary supermassive black holes (SMBHs). Using available optical spectra from the SDSS and DESI surveys, we identify 55 DPNEL sources among a sample of 187 XRGs. We find that the occurrence […]

$TbarT$ and root-$TbarT$ deformations in four-dimensional Chern-Simons theory

Posted by klaurent Tokyo

Kavli Affiliate: Masahito Yamazaki | Summary:The four-dimensional Chern-Simons (CS) theory provides a systematic procedure for realizing two-dimensional integrable field theories. It is therefore a natural question to ask whether integrable deformations of the theories can be realized in the four-dimensional CS theory. In this work, we study $TbarT$ and root-$TbarT$ deformations of two-dimensional integrable field […]

Kavli Affiliate: Li Xin Li| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:Recent advances in pre-trained language models (PLMs) have demonstrated their capabilities in capturing universal knowledge, making them promising for radar signal processing applications. Nevertheless, directly fine-tuning PLMs on radar signals is both computationally expensive and prone to overfitting, particularly in low signal-to-clutter […]
