Strain–Spintronics: Modulating Electronic and Magnetic Properties of Hf2MnC2O2 MXene by Uniaxial Strain

EMD Siriwardane, P Karki, YL Loh… - The Journal of Physical …, 2019 - ACS Publications
Next-generation spintronic nanoscale devices require two-dimensional (2D) materials with
robust ferromagnetism. Among 2D materials, MXenes are favorable for spintronic …

Stopping and reversing sound via dynamic dispersion tuning in a phononic metamaterial

P Karki, J Paulose - Physical Review Applied, 2021 - APS
Slowing down, stopping, and reversing a signal is a core functionality for information
processing. Here, we show that this functionality can be realized by tuning the dispersion of a …

Non-singular and singular flat bands in tunable phononic metamaterials

P Karki, J Paulose - Physical Review Research, 2023 - APS
Dispersionless flat bands can be classified into two types:(1) non-singular flat bands whose
eigenmodes are completely characterized by compact localized states, and (2) singular flat …

Prediction of Surgical Outcomes in Normal Pressure Hydrocephalus by MR Elastography

P Karki, MC Murphy, PM Cogswell… - American Journal …, 2024 - Am Soc Neuroradiology
BACKGROUND AND PURPOSE: Normal pressure hydrocephalus is a treatable cause of
dementia associated with distinct mechanical property signatures in the brain as measured by …

Engineering magnetic anisotropy and exchange couplings in double transition metal MXenes via surface defects

EMD Siriwardane, P Karki, YL Loh… - Journal of Physics …, 2020 - iopscience.iop.org
Two-dimensional (2D) materials have been experimentally proven to manifest almost all
types of material properties observed in bulk materials. However, 2D magnetism was elusive …

Evaluation of MR Elastography as a Noninvasive Diagnostic Test for Spontaneous Intracranial Hypotension

IT Mark, P Karki, J Cutsforth-Gregory… - American Journal …, 2024 - Am Soc Neuroradiology
BACKGROUND AND PURPOSE: Spontaneous intracranial hypotension is a condition
resulting from a leak of CSF from the spinal canal arising independent of a medical procedure. …

Electronic and mechanical properties of stiff rhenium carbide monolayers: A first-principles investigation

EMD Siriwardane, P Karki, C Sevik, D Çakır - Applied Surface Science, 2018 - Elsevier
In this study, we predicted two new stable metallic Resingle bondC based monolayer
structures with a rectangular (r-ReC 2 ) and a hexagonal (h-Re 2 C) crystal symmetry using first-…

Quantum vortex melting and superconductor insulator transition in a 2D Josephson junction array in a perpendicular magnetic field via diffusion Monte Carlo

P Karki, YL Loh - Journal of Physics: Condensed Matter, 2018 - iopscience.iop.org
In this study, we simulated a quantum rotor model describing a Josephson junction array (JJA)
in the phase representation at zero temperature in a perpendicular magnetic field (in units …

Critical exponents of dynamical conductivity in 2D percolative superconductor-insulator transitions: three universality classes

P Karki, YL Loh - Journal of Physics: Condensed Matter, 2016 - iopscience.iop.org
We simulate three types of random inductor-capacitor (LC) networks on $6000\times 6000$
square lattices. We calculate the dynamical conductivity using an equation-of-motion method …

Dielectric and diamagnetic susceptibilities near percolative superconductor-insulator transitions

YL Loh, P Karki - Journal of Physics: Condensed Matter, 2017 - iopscience.iop.org
Coarse-grained superconductor-insulator composites exhibit a superconductor-insulator
transition governed by classical percolation, which should be describable by networks of …
