Non-monotonic temperature dependence of electron viscosity and crossover to high-temperature universal viscous fluid in monolayer and bilayer graphene
Indra Yudhistira, Ramal Afrose, Shaffique Adam
Electrons in quantum matter behave like a fluid when the quantum-mechanical carrier-carrier scattering dominates over other relaxation mechanisms. By combining a microscopic treatm…
Spectral functions of the honeycomb lattice with both the Hubbard and long-range Coulomb Interactions
Ho-Kin Tang, Indra Yudhistira, Udvas Chattopadhyay +4
The absence of screening of the non-local Coulomb interaction in Dirac systems at charge neutrality leads to the breakdown of the Fermi liquid and divergence of the Fermi velocity.…
Theoretical determination of the effect of a screening gate on plasmon-induced superconductivity in twisted bilayer graphene
Liangtao Peng, Indra Yudhistira, Giovanni Vignale +1
The microscopic pairing mechanism for superconductivity in magic-angle twisted bilayer graphene remains an open question. Recent experimental studies seem to rule out a purely elec…
Carrier transport theory for twisted bilayer graphene in the metallic regime
Gargee Sharma, Indra Yudhistira, Nilotpal Chakraborty +4
Understanding the normal-metal state transport in twisted bilayer graphene near magic angle is of fundamental importance as it provides insights into the mechanisms responsible for…
Enhanced hydrodynamic transport in near magic angle twisted bilayer graphene
Mohammad Zarenia, Indra Yudishtira, Shaffique Adam +1
Using the semiclassical quantum Boltzmann theory and employing the Dirac model with twist angle-dependent Fermi velocity we obtain results for the electrical resistivity, the elect…
Dissipation-enabled hydrodynamic conductivity in a tunable bandgap semiconductor

Electronic transport in the regime where carrier-carrier collisions are the dominant scattering mechanism has taken on new relevance with the advent of ultraclean two-dimensional m…
Phase coherent transport in bilayer and trilayer MoS2
Leiqiang Chu, Indra Yudhistira, Hennrik Schmidt +3
Bilayer MoS2 is a centrosymmetric semiconductor with degenerate spin states in the six valleys at the corners of the Brillouin zone. It has been proposed that breaking of this inve…
Absence of strong localization at low conductivity in the topological surface state of low disorder Sb2Te3
Ilan T. Rosen, Indra Yudhistira, Gargee Sharma +5
We present low-temperature transport measurements of a gate-tunable thin film topological insulator system that features high mobility and low carrier density. Upon gate tuning to…
Gauge phonon dominated resistivity in twisted bilayer graphene near magic angle
I. Yudhistira, N. Chakraborty, G. Sharma +5
Recent experiments on twisted bilayer graphene (tBG) close to magic angle show that a small relative rotation in a van der Waals heterostructure greatly alters its electronic prope…
Microscopic theory for electron hydrodynamics in monolayer and bilayer graphene
Derek Y. H. Ho, Indra Yudhistira, Nilotpal Chakraborty +1
Electrons behave like a classical fluid with a momentum distribution function that varies slowly in space and time when the quantum mechanical carrier-carrier scattering dominates…
Electrostatic Modulation of the Electronic Properties of Dirac Semimetal Na3Bi
Jack Hellerstedt, Indra Yudhistira, Mark T. Edmonds +4
Large-area thin films of topological Dirac semimetal NaBi are grown on amorphous SiO:Si substrates to realise a field-effect transistor with the doped Si acting as back gat…
