Two-component dipolar condensates are now experimentally producible, and we
theoretically investigate the nature of supersolidity in this system. We predict the existence of …

More than 40 years ago, Andreev, Lifshitz and Chester suggested the possible existence of
a peculiar solid phase of matter, the microscopic constituents of which can flow superfluidly …

We investigate the zero-temperature excitation spectrum of two-dimensional soft-core
bosons for a wide range of parameters and across the phase transition from a superfluid to a …

This book presents an authoritative and in-depth treatment of potential energy landscape
theory, a powerful analytical approach to describing the atomic and molecular interactions in …

We study the superfluid properties of a system of fully polarized dipolar bosons moving in
the XY plane. We focus on the general case where the polarization field forms an arbitrary …

We investigate the rotational properties of a dipolar Bose-Einstein condensate trapped in a
toroidal geometry. Studying the ground states in the rotating frame and at fixed angular …

We theoretically investigate a supersolid structure taking the form of stacked, disk-shaped
superfluid droplets connected via a dilute superfluid, in an antidipolar condensate. A phase …

We show that knowledge of the time-dependent response of a trapped gas, subject to a
sudden rotation of a confining harmonic potential, allows for the determination of the …

A key challenge in condensed matter research is the optimization of topological insulator (TI)
compounds for the study and future application of their unique surface states. Truly …

We have utilized time-domain magnetoterahertz spectroscopy to investigate the low-
frequency optical response of the topological insulator Cu 0.02 Bi 2 Se 3 and Bi 2 Se 3 films …
