HandMovement Prediction Using LFP Data
(20110808)The last decade has seen a surge in the development of BrainMachine Interfaces (BMI) as assistive neural devices for paralysis patients. Current BMI research typically involves a subject performing movements by controlling ... 
Hardy's inequalities for Grushin operator and Hermite multipliers on Modulation spaces
This thesis consists of two broad themes. First one revolves around the Hardy's inequalities for the fractional power of Grushin operator $\G$ which is chased via two different approaches. In the first approach, we first ... 
Heavy flavour and direct photon probes of the gluon Sivers function
Traditionally the production of heavy quarkonia, heavyflavour mesons as well as of direct photons, has been used to constrain the gluon density inside the proton. In this thesis, I have assessed various heavy flavour ... 
Hermitian Metrics and Singular Riemann Surface Foliations
The main aim of this thesis is to understand curvature properties of a given hermitian metric by restricting it to the leaves of a suitable singular Riemann surface foliation. We will specifically consider the complete ... 
The Higgs Boson as a Probe of Physics Beyond the Standard Model at the Large Hadron Collider
(20180508)The nature of interactions of fundamental particles is governed by symmetries. These interactions are well described by an elegant and simple SU(3)c x SU(2)L x U(1)Y symmetric gauge theory that we call the Standard Model ... 
Higgs phenomenology and Dark Matter prospects in MSSM, NMSSM and U(1) extended SM
Particle physics today is at a juncture where all particles predicted within Standard Model (SM) have been discovered at the particle colliders while no particles from the realm of physics beyond the Standard Model (BSM) ... 
High Magnetic Field Neutron Stars : Cyclotron Lines and Polarization
(20180416)This thesis concerns with the study of Xray binaries which are gravitationally bound systems consisting of a compact object (either a neutron star or a black hole) and usually a non degenerate companion star, both rotating ... 
High Precision Optical Frequency Metrology
(20090722)Precise measurements of both absolute frequencies and small frequency differences of atomic energy levels have played an important role in the development of physics. For example, high precision measurements of absolute ... 
HighK Dielectrics–Studies on (Ta2O5)1x– (TiO2)x, (0 ≤ x ≤ 0.11), Thin Films
Recently the increasing demand for miniaturized electronic gadgets has raised the interest in searching the high dielectric constant (K) materials for memory elements. Among the investigated high dielectric constant metal ... 
HighResolution Spectroscopy in Atoms Using Coherent Control
(20171026)The subject of this thesis is the study of coherent interaction of light with matter (atoms) to improve the precision measurements and techniques. Special attention is drawn to get the narrow subnatural electromagnetically ... 
Higher Spins, Entanglement Entropy And Holography
(20170821)The idea of holography [1, 2] finds a concrete realization in form of the AdS/CFT correspondence [3, 4]. This duality relates a field theory with conformal symmetries to quantum gravity living in one higher dimension. In ... 
Homogeneous Operators
(20180613)A bounded operator T on a complex separable Hilbert space is said to be homogeneous if '(T ) is unitarily equivalent to T for all ' in M•ob, where M•ob is the M•obius group. A complete description of all homogeneous weighted ... 
Homogeneous Operators and Some Irreducible Representations of the Mobius Group
In this report, after recalling the definition of the M¨obius group, we define homogeneous operators, that is, operators T with the property '(T) is unitarily equivalent to T for all ' in the M¨obius group and prove some ... 
Homogenization of certain PDEs and associated optimal control problems on various rough domains
This thesis is devoted to the study of the asymptotic behavior of partial differential equations (PDEs) and associated boundary and interior optimal control problems in various oscillatory domains. The present thesis ... 
Homogenization of Optimal Control Problems in a Domain with Oscillating Boundary
(20171127)Mathematical theory of homogenization of partial differential equations is relatively a new area of research (3040 years or so) though the physical and engineering applications were well known. It has tremendous applications ... 
Hydrodynamic and hydromagnetic instabilities leading to turbulence in astrophysical accretion disks and their connection to laboratory shear flows
Accretion disks are astrophysical objects formed around a denser object, mainly in the form of a disk. In an accretion disk, matter spirals in and falls onto the central object. To match the observations, the underlying ... 
Hyperfine StructureMeasurement in Alkalimetal Atoms and Ytterbium Atom
(20180215)Atomic precision measurements provide a strong testing ground for new theoretical ideas and fundamental laws of physics. Measurement of the Lamb shift in the hydrogen atom is one of the best examples towards this it ... 
Hyperspectral and Spectropolarimetric Instrumentation for the Solar Atmosphere
The Sun is the closest star whose surface can be resolved to great a detail. Understanding the working of Sun helps in understanding a large fraction of stellar system as it falls under the spectral class G2V which is ...
