Anomalous spectrum in a non-Hermitian quasiperiodic chain
Soumya Ranjan Padhi, Sanchayan Banerjee, Tanay Nag +1
The spectra of particles in disordered lattices can either be completely extended or localized or can be intermediate which hosts both the localized and extended states separated f…
Distinguishing between topological Majorana and trivial zero modes via transport and shot noise study in an altermagnet heterostructure
Debashish Mondal, Amartya Pal, Arijit Saha +1
We theoretically investigate the transport and shot noise properties of a one-dimensional semiconducting nanowire with Rashba spin-orbit coupling~(SOC) placed in closed proximity t…
Statistical prethermalization in randomly kicked many-body classical rotor system
Aritra Kundu, Tanay Nag, Atanu Rajak
We explore the phenomena of prethermalization in a many-body classical system of rotors under aperiodic drives characterised by waiting time distribution (WTD), where the waiting t…
Sb2Se3 and SbBiSe3 Surface Capping and Biaxial Strain Co-Engineering for Tuning the Surface Electronic Properties of Bi2Se3 Nanosheet- A Density Functional Theory based Investigation
Naresh Bahadursha, Banasree Sadhukhan, Tanay Nag +2
In this work, for the first time, a density functional theory (DFT) based comprehensive theoretical study is performed on the surface electronic properties of Bi2Se3 nanosheet in t…
Transport signatures of single and multiple Floquet Majorana modes in one-dimensional Rashba nanowire and Shiba chain
Debashish Mondal, Rekha Kumari, Tanay Nag +1
We theoretically investigate the transport signature of single and multiple Floquet Majorana end modes~(FMEMs), appearing in an experimentally feasible setup with Rashba nanowire~(…
Corner modes in non-Hermitian next-nearest-neighbor hopping model
Arnob Kumar Ghosh, Arijit Saha, Tanay Nag
We consider a non-Hermitian (NH) analog of a second-order topological insulator, protected by chiral symmetry, in the presence of next-nearest neighbor hopping elements to theoreti…
Persistent anomaly in dynamical quantum phase transition in long-range non-Hermitian -wave Kitaev chain
Debashish Mondal, Tanay Nag
Considering a non-Hermitian version of -wave Kitaev chain in the presence of additional second nearest neighbour tunneling, we study dynamical quantum phase transition (DQPT) wh…
Mixed higher-order topology and nodal and nodeless flat band topological phases in a superconducting multiorbital model
Rodrigo Arouca, Tanay Nag, Annica M. Black-Schaffer
We investigate the topological phases that appear in an orbital version of the Benalcazar-Bernevig-Hughes (BBH) model in the presence of conventional spin-singlet -wave supercon…
Competing magnetic states on the surface of multilayer ABC-stacked graphene
Lauro B. Braz, Tanay Nag, Annica M. Black-Schaffer
We study interaction-mediated magnetism on the surface of ABC-multilayer graphene driven by its zero-energy topological flat bands. Using the random-phase approximation we treat on…
