Kramers nodal line in the charge density wave state of YTe and the influence of twin domains
Shuvam Sarkar, Joydipto Bhattacharya, Pramod Bhakuni +13
Recent studies have focused on the relationship between charge density wave (CDW) collective electronic ground states and nontrivial topological states. Using angle-resolved photoe…
Intrinsic and extrinsic plasmons in the hard x-ray photoelectron spectra of nearly free electron metals
Mohammad Balal, Shuvam Sarkar, Pramod Bhakuni +3
Collective plasmon excitations in solids that result from the process of photoemission are an important area of fundamental research. In this study, we identify a significant numbe…
Growth of bilayer stanene on a magnetic topological insulator aided by a buffer layer
Sajal Barman, Pramod Bhakuni, Shuvam Sarkar +10
Stanene, a two-dimensional counterpart to graphene, has the potential to exhibit novel quantum phenomena when grown on a magnetic topological insulator (MTI). This work demonstrate…
Bulk Electronic Structure of Ni2MnGa studied by Density Functional Theory and Hard X-ray Photoelectron Spectroscopy
Joydipto Bhattacharya, Pampa Sadhukhan, Shuvam Sarkar +4
A combined study employing density functional theory (DFT) using the experimentally determined modulated structures and bulk-sensitive hard x-ray photoelectron spectroscopy on sing…
Decagonal Sn clathrate on -Al-Ni-Co
Vipin Kumar Singh, Eva Pospisilova, Marek Mihalkovič +8
Decagonal quasiperiodic ordering of Sn thin film on -Al-Ni-Co, is shown based on scanning tunneling microscopy (STM), low-energy electron diffraction and density functional theo…
Charge density wave induced nodal lines in LaTe
Shuvam Sarkar, Joydipto Bhattacharya, Pampa Sadhukhan +11
LaTe is a noncentrosymmetric (NC) material with time reversal (TR) symmetry in which the charge density wave (CDW) is hosted by the Te bilayers. Here, we show that LaTe hos…
Electronic structure of Au-Sn compounds grown on Au(111)
Pampa Sadhukhan, Sajal Barman, Tufan Roy +4
The electronic structure of Au-Sn intermetallic layers of different compositions grown on Au(111) to the thickness of several nanometers has been studied in this work. The layer, i…
Unique Dirac and Triple point fermiology in simple transition metals and their binary alloys
Chiranjit Mondal, Chanchal K. Barman, Shuvam Sarkar +3
Noble metal surfaces (Au, Ag and Cu etc.) have been extensively studied for the Shockley type surface states (SSs). Very recently, some of these Shockley SSs have been understood f…
Dirac cone in a non-honeycomb surface alloy
Pampa Sadhukhan, Dhanshree Pandey, Vipin Kumar Singh +5
We demonstrate unexpected occurrence of linear bands resembling Dirac cone at the zone-center of AuSn surface alloy with $\left( \begin{smallmatrix} 2&1\\ 1&3 \end{smallmatrix}…
Quasiperiodic ordering in thick Sn layer on -Al-Pd-Mn: A possible quasicrystalline clathrate
Vipin Kumar Singh, Marek Mihalkovic, Marian Krajčí +9
Realization of an elemental solid-state quasicrystal has remained a distant dream so far in spite of extensive work in this direction for almost two decades. Here, we report the di…
