Driving non-trivial quantum phases in conventional semiconductors with intense excitonic fields
Vivek Pareek, David R. Bacon, Xing Zhu +12
Inducing novel quantum phases and topologies in materials using intense light fields is a key objective of modern condensed matter physics, but nonetheless faces significant experi…
Visualizing superconductivity in an inversion-symmetry-broken doped Weyl semimetal
Zhenyu Wang, Jorge Olivares, Hiromasa Namiki +5
The Weyl semimetal MoTe offers a rare opportunity to study the interplay between Weyl physics and superconductivity. Recent studies have found that Se substitution can boost th…
Moiré-localized interlayer exciton wavefunctions captured by imaging its electron and hole constituents
Ouri Karni, Elyse Barré, Vivek Pareek +21
Interlayer excitons (ILXs) - electron-hole pairs bound across two atomically thin layered semiconductors - have emerged as attractive platforms to study exciton condensation, singl…
Experimental measurement of the intrinsic excitonic wavefunction
Michael K. L. Man, Julien Madéo, Chakradhar Sahoo +15
An exciton, a two-body composite quasiparticle formed of an electron and hole, is a fundamental optical excitation in condensed-matter systems. Since its discovery nearly a century…
Visualization of two-dimensional transition dipole moment texture in momentum space using high-harmonic generation spectroscopy
K. Uchida, V. Pareek, K. Nagai +2
Highly nonlinear optical phenomena can provide access to properties of electronic systems which are otherwise difficult to access through conventional linear optical spectroscopies…
Directly visualizing the momentum forbidden dark excitons and their dynamics in atomically thin semiconductors
Julien Madéo, Michael K. L. Man, Chakradhar Sahoo +11
Resolving the momentum degree of freedom of excitons - electron-hole pairs bound by the Coulomb attraction in a photoexcited semiconductor, has remained a largely elusive goal for…
Direct Observation of Re-entrant Multiferroic CuO at High Pressures
Rajesh Jana, Pinku Saha, Vivek Pareek +5
We have carried out a detailed experimental investigation on CuO using dielectric constant, ac resistance, Raman spectroscopy and X-ray diffraction measurements at high pressures a…
