Engineering anomalous Floquet Majorana modes and their time evolution in helical Shiba chain
Debashish Mondal, Arnob Kumar Ghosh, Tanay Nag +1
We theoretically explore the Floquet generation of Majorana end modes~(MEMs) (both regular - and anomalous -modes) implementing a periodic sinusoidal modulation in chemical p…
Discovery of a magnetic Dirac system with large intrinsic non-linear Hall effect
Federico Mazzola, Barun Ghosh, Jun Fujii +9
Magnetic materials exhibiting topological Dirac fermions are attracting significant attention for their promising technological potential in spintronics. In these systems, the comb…
Finite temperature dynamical quantum phase transition in a non-Hermitian system
Debashish Mondal, Tanay Nag
We investigate the interplay between the non-Hermiticity and finite temperature in the context of mixed state dynamical quantum phase transition (MSDQPT). We consider a -wave su…

We theoretically investigate a practically realizable Floquet topological superconductor model, based on a one-dimensional Rashba nanowire and proximity induced -wave supercondu…
Disentangling structural and electronic properties in VO thin films: a genuine non-symmetry breaking Mott transition
Federico Mazzola, Sandeep Kumar Chaluvadi, Vincent Polewczyk +10
Phase transitions are key in determining and controlling the quantum properties of correlated materials. Here, by using the powerful combination of precise material synthesis and a…
VizInspect Pro -- Automated Optical Inspection (AOI) solution
Faraz Waseem, Sanjit Menon, Haotian Xu +1
Traditional vision based Automated Optical Inspection (referred to as AOI in paper) systems present multiple challenges in factory settings including inability to scale across mult…
Anomaly in dynamical quantum phase transition in non-Hermitian system with extended gapless phases
Debashish Mondal, Tanay Nag
The dynamical quantum phase transitions (DQPTs) and the associated winding numbers have been extensively studied in the context Hermitian system. We consider the non-Hermitian anal…
On the usefulness of lattice approximations for fractional Gaussian fields

Fractional Gaussian fields provide a rich class of spatial models and have a long history of applications in multiple branches of science. However, estimation and inference for fra…
Magnetic Topological Semimetal Phase with Electronic Correlation Enhancement in SmSbTe
Krishna Pandey, Debashis Mondal, John William Villanova +14
The ZrSiS family of compounds hosts various exotic quantum phenomena due to the presence of both topological nonsymmorphic Dirac fermions and nodal-line fermions. In this material…
The C-SHIFT algorithm for normalizing covariances
