Bosonic Collective Modes in Quantum Materials Studied with meV-resolved, Momentum-resolved EELS Open

Ali Husain, Matteo Mitrano, Melinda Rak, Samantha Rubeck, Anshul Kogar , et al. · 2019

A crowning achievement of twentieth-century condensed matter physics is the Fermi Liquid paradigm, which reduces the incredibly complicated problem of >10 23 interacting electrons to a simple singleelectron picture.However, a growing class…

Anomalous density fluctuations in a strange metal Open

Matteo Mitrano, Ali Husain, Sean Vig, Anshul Kogar, Melinda Rak , et al. · 2018

Significance The strange metal is a poorly understood state of matter found in a variety of quantum materials, notably both Cu- and Fe-based high-temperature superconductors. Strange metals exhibit a nonsaturating, T-linear electrical resi…

Signatures of exciton condensation in a transition metal dichalcogenide Open

Anshul Kogar, Melinda Rak, Sean Vig, Ali Husain, Felix Flicker , et al. · 2017

Probing an excitonic condensate Excitons—bound states of electrons and holes in solids—are expected to form a Bose condensate at sufficiently low temperatures. Excitonic condensation has been studied in systems such as quantum Hall bilayer…

Report on 1509.04230v4 Open

Sean Vig, Anshul Kogar, Matteo Mitrano, Ali Husain, Luc Venema , et al. · 2017

One of the most fundamental properties of an interacting electron system is its frequency-and wave-vector-dependent density response function, χ(q, ω).The imaginary part, χ (q, ω), defines the fundamental bosonic charge excitations of the …

Singular density fluctuations in the strange metal phase of a copper-oxide superconductor Open

Matteo Mitrano, Ali Husain, Sean Vig, Anshul Kogar, Melinda Rak , et al. · 2017

High-temperature superconductivity arises out of an anomalous normal state commonly referred to as a bad or metal, since it lacks the usual signatures of electron quasiparticles. In ordinary metals, such quasiparticles manifest as propaga…

Quasiparticle interference and strong electron–mode coupling in the quasi-one-dimensional bands of Sr2RuO4 Open

Zhenyu Wang, Daniel Walkup, Philip Derry, Thomas Scaffidi, Melinda Rak , et al. · 2017

Characterization of collective phenomena in cuprate superconductors by momentum-resolved electron energy loss spectroscopy Open

Sean Vig · 2017

There exists a wide variety of strongly correlated electronic materials, including high temperature superconductors, exotic topological insulators, and charge density wave materials, that exhibit emergent behavior that cannot be understood…

SymPy: symbolic computing in Python Open

Aaron Meurer, Christopher P. Smith, Mateusz Paprocki, Ondřej Čertı́k, Sergey B Kirpichev , et al. · 2017

SymPy is an open source computer algebra system written in pure Python. It is built with a focus on extensibility and ease of use, through both interactive and programmatic applications. These characteristics have led SymPy to become a pop…
