Optimization Landscape Geometry in VQE for Frustrated Quantum Spin Models
Vojtěch Novák, Ivan Zelinka, Swagatam Das +1
We benchmark eight classical optimizers for exact-statevector VQE calculations on a controlled hierarchy of frustrated spin models, ranging from a diagonal Ising glass to transvers…
Estimating Size of the Union of Sets in Streaming Model
Kuldeep S. Meel, N. V. Vinodchandran, Sourav Chakraborty
We study estimating the size of the union of sets , where each is presented implicitly and arrives in a stream. We introduce Delphic sets, a class of…
Algorithms and complexity for geodetic sets on interval and chordal graphs
Dibyayan Chakraborty, Sandip Das, Florent Foucaud +2
We study the computational complexity of finding the geodetic number of a graph on chordal graphs and interval graphs. A set of vertices of a graph is a \textit{geodetic se…
Emergence of Transport Regimes from the Axial Field-Induced Interfacial Gradients in Uniform Surface Potential Nanopores
Pramodt Srinivasula, Doyel Pandey
Gate-modulated nanopores have emerged as a promising platform for achieving ion selectivity and ionic current rectification (ICR) with the advantage of active field-based control.…
On the Haagerup property for partial crossed products
Md Amir Hossain, Chaitanya J. Kulkarni
Let be a partial dynamical system and let denote the associated reduced partial crossed product. In this article, we introduce the Haagerup property fo…
Impact of the Infrared Cutoff on Structure Formation in Tsallis Holographic Dark Energy
Biswajit Das
We investigate the viability of Tsallis holographic dark energy (THDE) models, focusing on the role of the infrared (IR) cutoff in the growth of cosmic structures. Considering two…
Model-independent reconstruction of cosmic thermodynamics and dark energy dynamics
Afaq Maqsood, Tanima Duary
We perform a model-independent investigation of the thermodynamic evolution of the Universe by reconstructing the expansion history from observational data using Gaussian Process r…
Forecasting of Multiple Seasonal Categorical Time Series Using Fourier Series with Application to AQI Data of Kolkata
Anirban Ghosh, Raju Maiti
Multiple seasonalities have been widely studied in continuous time series using models such as TBATS, for instance in electricity demand forecasting. However, their treatment in ca…
Probing Interacting Dark Sectors with upcoming Post-Reionization and Galaxy Surveys
Rahul Shah, Antara Dey, Purba Mukherjee +1
We investigate the constraining power of future post-reionization and galaxy surveys on possible interactions between dynamical dark energy and dark matter. The analysis focuses on…
Thermal enhancement of inflationary magnetic fields
Arjun Berera, Suddhasattwa Brahma, Zizang Qiu +1
We investigate primordial magnetogenesis by assuming the gauge field is prepared in a thermal state during inflation rather than the standard Bunch-Davies vacuum. The temperature $…
Prospects of Indirect Detection of Dark Matter via Primordial Black Hole Induced Gravitational Waves
Debarun Paul, Md Riajul Haque, Supratik Pal
Primordial black holes (PBHs), produced in the early Universe, can source a stochastic background of induced gravitational waves (GWs) and provide a non-thermal origin for dark mat…
-extreme points of unital completely positive maps invariant under group action
Chaitanya J. Kulkarni
In this work, we study a sub-collection of unital completely positive maps from a unital -algebra to , the algebra of bounded linear…
