Electronic Structure Studies of FeSi: A Chiral Topological System
Susmita Changdar, S. Aswartham, Anumita Bose +7
Most recent observation of topological Fermi arcs on the surface of manyfold degenerate B20 systems, CoSi and RhSi, have attracted enormous research interests. Although an another…
Tunneling density of states in a Y junction of Tomonaga-Luttinger liquid wires: A density matrix renormalization group study
Monalisa Singh Roy, Manoranjan Kumar, Sourin Das
It is well known that the pristine bulk of an interacting one-dimensional system in Tomonaga-Luttinger liquid (TLL) phase shows power law suppression of quasi-particle tunneling am…
Sufficient conditions for quantum advantage in random access code protocols with two-qubit states
Som Kanjilal, C Jebarathinam, Tomasz Paterek +1
Random access code (RAC) is an important communication protocol to obtain information about a randomly specified substring of an n-bit string, while only having limited information…
Holographic computation of Wilson loops in a background with broken conformal invariance and finite chemical potential
Ashis Saha, Sunandan Gangopadhyay
In this paper, we follow a `bottom-up' AdS/QCD approach to holographically probe the dynamics of a moving pair inside a strongly coupled plasma at the boundary. We consi…
Emergent vortex-electron interaction from dualization
Shantonu Mukherjee, Amitabha Lahiri
We consider the Abelian Higgs model in 3+1 dimensions with vortex lines, into which charged fermions are introduced. This could be viewed as a model of a type-II superconductor wit…
-wave holographic superconductors with massive vector condensate in Born-Infeld electrodynamics
Ankur Srivastav, Debabrata Ghorai, Sunandan Gangopadhyay
In this paper, we have studied the effect of Born-Infeld electrodynamics in holographic -wave superconductors with massive vector condensation. We have analysed this model in th…
