Quantum Kinetic Theory of Nonlinear Optical Currents: Finite Fermi surface and Fermi sea contributions

Pankaj Bhalla, Kamal Das, Amit Agarwal +1

The quantum kinetic framework provides a versatile method for investigating the dynamical optical and transport currents of crystalline solids. In this paper, starting from the den…

Crossover from exciton polarons to trions in doped two-dimensional semiconductors at finite temperature

A. Tiene, B. C. Mulkerin, J. Levinsen +2

We study systematically the role of temperature in the optical response of doped two-dimensional semiconductors. By making use of a finite-temperature Fermi-polaron theory, we reve…

Giant gate-tunable renormalization of spin-correlated flat-band states and bandgap in a 2D magnetic insulator

Pin Lyu, Joachim Sødequist, Xiaoyu Sheng +8

Emergent quantum phenomena in two-dimensional van der Waal (vdW) magnets are largely governed by the interplay between the exchange and Coulomb interactions. The ability to tune th…

Thermography of the superfluid transition in a strongly interacting Fermi gas

Zhenjie Yan, Parth B. Patel, Biswaroop Mukherjee +3

Heat transport is a fundamental property of all physical systems and can serve as a fingerprint identifying different states of matter. In a normal liquid a hot spot diffuses while…

Viability of rotation sensing using phonon interferometry in Bose-Einstein condensates

Charles W. Woffinden, Andrew J. Groszek, Guillaume Gauthier +7

We demonstrate the use of a ring-shaped Bose-Einstein condensate as a rotation sensor by measuring the interference between two counter-propagating phonon modes imprinted azimuthal…

Weyl excitations via helicon-phonon mixing in conducting materials

Dmitry K. Efimkin, Sergey Syzranov

Quasiparticles with Weyl dispersion can display an abundance of novel topological, thermodynamic and transport phenomena, which is why novel Weyl materials and platforms for Weyl p…
