quantum generalization of the well-known Max-$d$-Cut problem. The Quantum
Max-$d$-Cut problem involves finding a quantum state that maximizes the
expected energy associated with the projector onto the antisymmetric subspace
of two, $d$-dimensional ... | http://arxiv.org/abs/2309.10957v2 |
In this paper, we introduce the representation of anti-pre-Lie algebras and
give the second cohomology group of anti-pre-Lie algebras. As applications,
first, we study linear deformations of anti-pre-Lie algebras. The notion of a
Nijenhuis operator on an anti-pre-Lie algebra is introduced which can generate
a trivial l... | http://arxiv.org/abs/2301.06917v2 |
We deduce the existence of smooth $U(1)$- and $Sp(1)$-actions on certain
exotic spheres using complex and quaternionic analogues of the Mahowald
{(root)} invariant. In particular, we prove that the complex (respectively,
quaternionic) Mahowald invariant takes an element of $\pi_k^s$ represented by a
homotopy sphere $\S... | http://arxiv.org/abs/2309.04275v1 |
Earlier work took as universal mapping class group the collection PPSL(2,Z)
of all piecewise PSL(2,Z) homeomorphisms of the unit circle S^1 with finitely
many breakpoints among the rational points. The spin mapping class group
P(SL(2,Z)) introduced here consists of all piecewise-constant maps from S^1 to
SL(2,Z) which ... | http://arxiv.org/abs/2309.13709v3 |
Much of the strength of quantum cryptography may be attributed to the
no-cloning property of quantum information. We construct three new
cryptographic primitives whose security is based on uncloneability, and that
have in common that their security can be established via a novel
monogamy-of-entanglement (MoE) property:... | http://arxiv.org/abs/2303.00048v1 |
Adversarial object rearrangement in the real world (e.g., previously unseen
or oversized items in kitchens and stores) could benefit from understanding
task scenes, which inherently entail heterogeneous components such as current
objects, goal objects, and environmental constraints. The semantic
relationships among the... | http://arxiv.org/abs/2309.15378v1 |
We are studying the use of deep neural networks (DNNs) to identify and locate
primary vertices (PVs) in proton-proton collisions at the LHC. Earlier work
focused on finding primary vertices in simulated LHCb data using a hybrid
approach that started with kernel density estimators (KDEs) derived
heuristically from the e... | http://arxiv.org/abs/2309.12417v2 |
A hypergraph generalizes the concept of an ordinary graph. In an ordinary
graph, edges connect pairs of vertices, whereas in a hypergraph, hyperedges can
connect multiple vertices at a time. In this paper, we obtain a relationship
between the characteristic polynomial of Seidel and adjacency matrices of
hypergraph and ... | http://arxiv.org/abs/2309.09751v1 |
We present findings of the detection of Magnesium II (Mg II, {\lambda} =
2796, 2803 {\AA}) absorbers from the early data release of the Dark Energy
Spectroscopic Instrument (DESI). DESI is projected to obtain spectroscopy of
approximately 3 million quasars (QSOs), of which over 99% are anticipated to be
at redshifts gr... | http://arxiv.org/abs/2305.20016v3 |
Contrastive Language-Image Pre-training (CLIP) is an approach that has
advanced research and applications in computer vision, fueling modern
recognition systems and generative models. We believe that the main ingredient
to the success of CLIP is its data and not the model architecture or
pre-training objective. However... | http://arxiv.org/abs/2309.16671v4 |
Continual learning involves training neural networks incrementally for new
tasks while retaining the knowledge of previous tasks. However, efficiently
fine-tuning the model for sequential tasks with minimal computational resources
remains a challenge. In this paper, we propose Task Incremental Continual
Learning (TI-CL... | http://arxiv.org/abs/2302.14314v2 |
Despite recent intensive research on topological aspects of open quantum
systems, effects of strong interactions have not been sufficiently explored. In
this paper, we demonstrate that complex-valued interactions induce the
Liouvillian skin effect by analyzing a one-dimensional correlated model with
two-body loss. We s... | http://arxiv.org/abs/2305.19697v2 |
Anticipating the motion of all humans in dynamic environments such as homes
and offices is critical to enable safe and effective robot navigation. Such
spaces remain challenging as humans do not follow strict rules of motion and
there are often multiple occluded entry points such as corners and doors that
create opport... | http://arxiv.org/abs/2309.17209v1 |
