Effects of Pressure on the Electronic Structures of LaOFeP

, 2013
We studied the electronic structures of LaOFeP under applied pressure using first-principles calculations. The electronic density of states at the Fermi level decreases continuously with increasing pressure.

Isolated zeros destroy Fermi surface in holographic models with a lattice

Journal of High Energy Physics, 2020
We study the fermionic spectral density in a strongly correlated quantum system described by a gravity dual. In the presence of periodically modulated chemical potential, which models the effect of the ionic lattice, we explore the shapes of the ...

Composite fermions in bands with N-fold rotational symmetry

, 2017
We study the effect of band anisotropy with discrete rotational symmetry $C_N$ (where $N\ge 2$) in the quantum Hall regime of two-dimensional electron systems. We focus on the composite Fermi liquid (CFL) at half filling of the lowest Landau level.

Photoemission studies of Ga$_{1-x}$Mn$_{x}$As: Mn-concentration dependent properties

, 2002
Using angle-resolved photoemission, we have investigated the development of the electronic structure and the Fermi level pinnning in Ga$_{1-x}$Mn$_{x}$As with Mn concentrations in the range 1--6%.

Fermi-level-dependent charge-to-spin current conversion by Dirac surface states of topological insulators [PDF]

Nature Physics, 2015
The spin–momentum locking of Dirac surface states offers intriguing possibilities for converting between charge and spin currents. Experiments show that fine tuning of the Fermi level is critical for maximizing the efficiency of such conversions.

Berry phase of the composite-fermion Fermi Sea: Effect of Landau-level mixing

, 2018
We construct explicit lowest-Landau-level wave functions for the composite-fermion Fermi sea and its low energy excitations following a recently developed approach [Pu, Wu and Jain, Phys. Rev. B 96, 195302 (2018)] and demonstrate them to be very accurate

Electronic structure of CaFe2As2

, 2013
We investigate the electronic structure of CaFe$_2$As$_2$ using high resolution photoemission spectroscopy. Experimental results exhibit three energy bands crossing the Fermi level making hole pockets around the $\Gamma$-point.
