Quantification of nonlinear absorption in ternary As-Sb-Se chalcogenide glasses
P. Pradhan, Pritam Khan, J. R. Aswin +4
In this article, we studied intensity dependent third order nonlinear optical response in ternary As40Sb7Se53 and As40Sb10Se50 chalcogenide glasses by employing nanosecond Z-scan t…
Time-reversal symmetry breaking in Re-based superconductors
T. Shang, M. Smidman, S. K. Ghosh +15
To trace the origin of time-reversal symmetry breaking (TRSB) in Re-based superconductors, we performed comparative muon-spin rotation/relaxation (SR) studies of superconducting…
Intricate modulation of interlayer coupling at GO/MoSe2 interface: application in time-dependent optics and device transport
Tuhin Kumar Maji, Kumar Vaibhav, Samir Kumar Pal +3
In GO/MoSe2 semiconductor heterostructure, we have demonstrated a subtle control on the doping dynamics by modulating interlayer coupling through the combination of strain-reducing…
Enhancement of crossed Andreev reflection in a Kitaev ladder connected to normal metal leads
Ritu Nehra, Devendra Singh Bhakuni, Auditya Sharma +1
We study nonlocal transport in a two-leg Kitaev ladder connected to two normal metals. The coupling between the two legs of the ladder when the legs are maintained at a (large) sup…
On minimal complements in groups
Arindam Biswas, Jyoti Prakash Saha
Let be nonempty subsets in an arbitrary group . The set is said to be a complement to if and it is minimal if no proper subset of is a co…
`Muhammad Ali effect' and incoherent destruction of Wannier-Stark localization in a stochastic field
Devendra Singh Bhakuni, Sushanta Dattagupta, Auditya Sharma
We calculate an exact expression for the probability propagator for a noisy electric field driven tight-binding lattice. The noise considered is a two-level jump process or a teleg…
Quantum simulation of long range quantum spin glass with strong area-law violation using trapped ions
Nilanjan Roy, Auditya Sharma, Rick Mukherjee
Ground states of local Hamiltonians are known to obey the entanglement entropy area law. While area law violation of a mild kind (logarithmic) is commonly encountered, strong area-…
Dark matter stability and Dirac neutrinos using only Standard Model symmetries
Cesar Bonilla, Salvador Centelles Chuliá, Ricardo Cepedello +2
We provide a generic framework to obtain stable dark matter along with naturally small Dirac neutrino masses generated at the loop level. This is achieved through the spontaneous b…
Shapes and paths of an air bubble rising in quiescent liquids
DM Sharaf, A R Premlata, Manoj Kumar Tripathi +2
Shapes and paths of an air bubble rising inside a liquid are investigated experimentally. About three hundred experiments are conducted in order to generate a phase plot in the Gal…
Superconducting properties of the noncentrosymmetric superconductor LaPtGe
Sajilesh. K. P., D. Singh, P. K. Biswas +2
We report superconducting properties of noncentrosymmetric superconductor LaPtGe which crystallizes in noncentrosymmetric -ThSi structure. The magnetization, resistivit…
Reconstructing bifurcation behavior of a nonlinear dynamical system by introducing weak noise
Debraj Das, Sayan Roy, Shamik Gupta
For a model nonlinear dynamical system, we show how one may obtain its bifurcation behavior by introducing noise into the dynamics and then studying the resulting Langevin dynamics…
Tracking Rydberg atoms with Bose-Einstein Condensates
Shiva Kant Tiwari, Sebastian Wüster
We propose to track position and velocity of mobile Rydberg excited impurity atoms through the elastic interactions of the Rydberg electron with a host condensate. Tracks first occ…
Stabilizing Graph-dependent Switched Systems
Nikita Agarwal
We give sufficient conditions for stability of a continuous-time linear switched system consisting of finitely many subsystems. The switching between subsystems is governed by an u…
Smooth phase transition of energy equilibration in a springy Sinai billiard
Kushal Shah
Statistical equilibration of energies in a slow-fast system is a fundamental open problem in physics. In a recent paper, it was shown that the equilibration rate in a springy billi…
Unifying averaged dynamics of the Fokker-Planck equation for Paul traps
Arindam Bhattacharjee, Kushal Shah, Anindya Chatterjee
Collective dynamics of a collisional plasma in a Paul trap is governed by the Fokker-Planck equation, which is usually assumed to lead to a unique asymptotic time-periodic solution…
Quantitative weighted estimates for Rubio de Francia's Littlewood--Paley square function
R. Garg, L. Roncal, S. Shrivastava
We consider the Rubio de Francia's Littlewood--Paley square function associated with an arbitrary family of intervals in with finite overlapping. Quantitative weighted…

Surajit Sarkar, Suhas Gangadharaiah
We present a detailed study of the imaginary and real parts of the spin-susceptibility of silicene which can be generalized to other buckled honeycomb structure. We find that while…

Sambuddha Sanyal, Kusum Dhochak, Subhro Bhattacharjee
We study the uniform time reversal invariant quantum spin liquid (QSL) with low energy fermionic quasi-particles for rare earth pyrochlore magnets and explore its magnetic i…
