Apparent Planckian scattering from local polaron formation
Brian Yong-Ho Lee, Chaitanya Murthy
We propose a simple mechanism for apparent Planckian scattering based on local polaron formation, in which with emerges from quasie…
Evolution of the Superfluid Density in Infinite-Layer Nickelates
Bai Yang Wang, Shannon P. Harvey, Kyuho Lee +6
Nickelate superconductors provide a valuable new platform for the study of unconventional superconductivity that is complementary to the cuprates. One of the central puzzles about…
Pauli 'unlimited': magnetic field induced-superconductivity in UTe
Josephine J. Yu, Yue Yu, Chaitanya Murthy +1
Inspired by the observation of extreme field-boosted superconductivity in uranium ditelluride, we present a scenario in which superconductivity can be induced by a strong Zeeman fi…
Modified interferometer to measure anyonic braiding statistics
Steven A. Kivelson, Chaitanya Murthy
Existing quantum Hall interferometers measure twice the braiding phase, , of Abelian anyons, i.e. the phase accrued when one quasi-particle encircles another clockwise. We…
Luttinger Liquid phase in the Aubry-André Hubbard chain
Runze Chi, Josephine J. Yu, Chaitanya Murthy +1
We study the interplay between an on-site Hubbard repulsion and quasiperiodic potential in one-dimensional fermion chains using the density matrix renormalization group. We find th…
Thermal transport measurements of the charge density wave transition in CsVSb
Erik D. Kountz, Chaitanya R. Murthy, Dong Chen +6
We study thermalization and thermal transport in single crystals of CsVSb through the CDW transition by directly measuring thermal diffusivity (), thermal conductivity (…
Anomalous superfluid density in a disordered charge density wave material: Pd-intercalated ErTe
Yusuke Iguchi, Joshua A. Straquadine, Chaitanya Murthy +4
We image local superfluid density in single crystals of Pd-intercalated ErTe below the superconducting critical temperature, , well below the onset temperature, ,…
Dynamical defects in a two-dimensional Wigner crystal: self-doping and kinetic magnetism
Kyung-Su Kim, Ilya Esterlis, Chaitanya Murthy +1
We study the quantum dynamics of interstitials and vacancies in a two-dimensional Wigner crystal (WC) using a semi-classical instanton method that is asymptotically exact at low de…
Strange-metal behavior in a Fermi liquid with strange scatterers
Erez Berg, Gaël Grissonnanche, Steven A. Kivelson +4
A variety of low-temperature, normal-state properties of optimally and overdoped cuprate superconductors, including the DC and optical transport responses, are sufficiently anomalo…
Interstitial-induced ferromagnetism in a two-dimensional Wigner crystal
Kyung-Su Kim, Chaitanya Murthy, Akshat Pandey +1
The two-dimensional Wigner crystal (WC) occurs in the strongly interacting regime () of the two-dimensional electron gas (2DEG). The magnetism of a pure WC is determined…
Non-Abelian eigenstate thermalization hypothesis
Chaitanya Murthy, Arman Babakhani, Fernando Iniguez +2
The eigenstate thermalization hypothesis (ETH) explains why chaotic quantum many-body systems thermalize internally if the Hamiltonian lacks symmetries. If the Hamiltonian conserve…
Character of the "normal state" of the nickelate superconductors
Kyuho Lee, Bai Yang Wang, Motoki Osada +10
The occurrence of superconductivity in proximity to various strongly correlated phases of matter has drawn extensive focus on their normal state properties, to develop an understan…
A stability bound on the -linear resistivity of conventional metals
Chaitanya Murthy, Akshat Pandey, Ilya Esterlis +1
Perturbative considerations account for the properties of conventional metals, including the range of temperatures where the transport scattering rate is , wh…
Quantum-critical dynamics of a Josephson junction at the topological transition
Vladislav D. Kurilovich, Chaitanya Murthy, Pavel D. Kurilovich +3
We find the admittance of a Josephson junction at or near a topological transition. The dependence of the admittance on frequency and temperature at the critical point is un…
Energy spectrum and current-phase relation of a nanowire Josephson junction close to the topological transition
Chaitanya Murthy, Vladislav D. Kurilovich, Pavel D. Kurilovich +3
A semiconducting nanowire proximitized by an -wave superconductor can be tuned into a topological state by an applied magnetic field. This quantum phase transition is marked by…
Almost Perfect Metals in One Dimension
Chaitanya Murthy, Chetan Nayak
We show that a one-dimensional quantum wire with as few as 2 channels of interacting fermions can host metallic states of matter that are stable against all perturbations up to $q^…
Bounds on chaos from the eigenstate thermalization hypothesis
Chaitanya Murthy, Mark Srednicki
We show that the known bound on the growth rate of the out-of-time-order four-point correlator in chaotic many-body quantum systems follows directly from the general structure of o…
Structure of chaotic eigenstates and their entanglement entropy
Chaitanya Murthy, Mark Srednicki
We consider a chaotic many-body system (i.e., one that satisfies the eigenstate thermalization hypothesis) that is split into two subsystems, with an interaction along their mutual…
Spectral response of Josephson junctions with low-energy quasiparticles
Anna Keselman, Chaitanya Murthy, Bernard van Heck +1
We study nanowire-based Josephson junctions shunted by a capacitor and take into account the presence of low-energy quasiparticle excitations. These are treated by extending conven…
