Observation and Structural Control of Charge-Density-Waves resonating with Terahertz Frequencies in NdNiO3

Rakesh Rana, Parul Pandey, S. S. Prabhu +1

Formation of charge-density-waves in ordered electronic phases (such as charge-order) is an emergent phenomenon in the perovskite class of correlated oxides. This scenario is visua…

Modeling HI distribution and kinematics in the edge-on dwarf irregular galaxy KK250

Narendra Nath Patra, Arunima Banerjee, Jayaram N. Chengalur +1

We model the observed vertical distribution of the neutral hydrogen (HI) in the faint (M_B ~ -13.7 mag) edge-on dwarf irregular galaxy KK250. Our model assumes that the galaxy cons…

Optimal quantum tomography with constrained elementary measurements arising from unitary bases

S. Chaturvedi, Sibasish Ghosh, K. R. Parthasarathy +1

The purpose of this paper is to introduce techniques of obtaining optimal ways to determine a d-level quantum state or distinguish such states. It entails designing constrained ele…

Entanglement properties of positive operators with ranges in completely entangled subspaces

R Sengupta, Arvind, Ajit Iqbal Singh

We prove that the projection on a completely entangled subspace S of maximum dimension in a multipartite quantum system obtained by Parthasarathy is not positive under partial tran…

Tailoring between network rigidity and nanosecond transient absorption in a-GexAs35-xSe65 thin films

Pritam Khan, Tarun Saxena, K. V. Adarsh

In this letter, we report the first observation of dramatic decrease in nanosecond (ns) pulsed laser induced transient absorption (TA) in a-GexAs35-xSe65 thin films by tuning the a…

Persistent entanglement in a class of eigenstates of quantum Heisenberg spin glasses

Arun Kannawadi, Auditya Sharma, Arul Lakshminarayan

The eigenstates of a quantum spin glass Hamiltonian with long-range interaction are examined from the point of view of localisation and entanglement. In particular, low particle se…

Raychaudhuri Equation in an Anisotropic Universe with Anisotropic Sources

Manabendra Sharma

In this paper we investigate the fate of the universe with an anisotropic background sourced by anisotropic matter. We see the behaviour of the Raychaudhuri Equation and investigat…

Entropy current for non-relativistic fluid

Nabamita Banerjee, Suvankar Dutta, Akash Jain +1

We study transport properties of a parity-odd, non-relativistic charged fluid in presence of background electric and magnetic fields. To obtain stress tensor and charged current fo…

Nanosecond light induced, thermally tunable transient dual absorption bands in a-Ge5As30Se65 thin film

Pritam Khan, Tarun Saxena, K. V. Adarsh

In this article, we report the first observation of nanosecond laser induced transient dual absorption bands, one in the bandgap (TA1) and another in the sub-bandgap (TA2) regions…

Coexistence of fast photodarkening and slow photobleaching in Ge19As21Se60 thin films

Pritam Khan, A. R. Barik, E. M. Vinod +3

We experimentally demonstrate the coexistence of two opposite photo-effects, viz. fast photodarkening (PD) and slow photobleaching (PB) in Ge19As21Se60 thin films, when illuminated…

Role of Ge:As ratio in controlling the light-induced response of a-GexAs35-xSe65 thin films

Pritam Khan, H. Jain, K. V. Adarsh

In this paper, we present interesting results on the quantification of photodarkening (PD), photobleaching (PB) and transient PD (TPD) in a- GexAs35-xSe65 thin films as a function…

Rates of convergence for Renyi entropy in extreme value theory

Ali Saeb

Max stable laws are limit laws of linearly normalized partial maxima of independent identically distributed random variables. Saeb (2014) proves that the Renyi entropy of order b (…

Viscoelasticity of a colloidal gel during dynamical arrest: evolution through the critical gel and comparison with a soft colloidal glass

Ajay Singh Negi, Carissa G. Redmon, Subramanian Ramakrishnan +1

We consider gelation of colloidal particles in suspension after cessation of shear flow. Particle aggregation is driven by a temperature-tunable attractive potential which controls…
