Autoencoders for semivisible jet detection

Journal of High Energy Physics, 2022
The production of dark matter particles from confining dark sectors may lead to many novel experimental signatures. Depending on the details of the theory, dark quark production in proton-proton collisions could result in semivisible jets of particles ...

A splitting formula for the spectral flow of the odd signature operator on 3-manifolds coupled to a path of SU(2) connections [PDF]

, 2004
We establish a splitting formula for the spectral flow of the odd signature operator on a closed 3-manifold M coupled to a path of SU(2) connections, provided M = S cup X, where S is the solid torus.

Dimensionality, topology, energy, the cosmological constant, and signature change [PDF]

, 1995
Using the concept of real tunneling configurations (classical signature change) and nucleation energy, we explore the consequences of an alternative minimization procedure for the Euclidean action in multiple-dimensional quantum cosmology.

Experimental signature of a topological quantum dot

Nanoscale, 2020
Topological insulator nanoparticles (TINPs) host topologically protected Dirac surface states, just like their bulk counterparts.

ENTROPY SIGNATURES OF TOPOLOGICAL PHASE TRANSITIONS [PDF]

ЖУРНАЛ ЭКСПЕРИМЕНТАЛЬНОЙ И ТЕОРЕТИЧЕСКОЙ ФИЗИКИ, 2018
We review the behavior of the entropy per particle in various two-dimensional electronic systems. The entropy per particle is an important characteristic of any many body system that tells how the entropy of the ensemble of electrons changes if one adds one more electron.

Transport Signatures of Fermi Surface Topology Change in BiTeI [PDF]

, 2015
We report a quantum magnetotransport signature of a change in Fermi surface topology in the Rashba semiconductor BiTeI with systematic tuning of the Fermi level $E_F$.

The expanding Asgard archaea and their elusive relationships with Eukarya

mLife, 2022
The discovery of Asgard archaea and the exploration of their diversity over the last 6 years have deeply impacted the scientific community working on eukaryogenesis, rejuvenating an intense debate on the topology of the universal tree of life (uTol ...

Accelerator Testing of the General Antiparticle Spectrometer, a Novel Approach to Indirect Dark Matter Detection [PDF]

, 2005
We report on recent accelerator testing of a prototype general antiparticle spectrometer (GAPS). GAPS is a novel approach for indirect dark matter searches that exploits the antideuterons produced in neutralino-neutralino annihilations.

Circles in the Sky: Finding Topology with the Microwave Background Radiation [PDF]

, 1996
If the universe is finite and smaller than the distance to the surface of last scatter, then the signature of the topology of the universe is writ large on the microwave background sky.

Factoriality and the Pin-Reutenauer procedure [PDF]

Discrete Mathematics & Theoretical Computer Science, 2016
We consider implicit signatures over finite semigroups determined by sets of pseudonatural numbers. We prove that, under relatively simple hypotheses on a pseudovariety V of semigroups, the finitely generated free algebra for the largest such signature ...
