An asymptotically solvable model of many-body critical phases: mobility edges, scars, and inverted scars
Yi-Ting Tu, Zi-Jian Li, Sankar Das Sarma
While the prethermal regime of random many-body localized (MBL) systems is dominated by accidental many-body resonances, another class of resonances, originating from the underlyin…
Stripe-tuned superconductivity in single-flavor metals with nontrivial quantum geometry
Yi-Ting Tu, Yang-Zhi Chou, Yi Huang +1
We study how the interplay between nontrivial quantum geometry and an applied stripe potential affects superconductivity in a two-dimensional single-flavor metal. Assuming a weak c…
Coherently synchronized oscillations in many-body localization
Zi-Jian Li, Yi-Ting Tu, Sankar Das Sarma
We find an unexpected phenomenon of coherently synchronized oscillations in a mirror-symmetric many-body localized system. A synchronization transition of the spin oscillations is…
Conventional and practical metallic superconductivity arising from repulsive Coulomb coupling
Sankar Das Sarma, Jay D. Sau, Yi-Ting Tu +1
A concrete question is discussed: Can there be conventional s-wave superconductivity in regular 3D (or 2D) metals, i.e., electrons in a jellium background, interacting via the stan…
Many-body localization in a slowly varying potential
Zi-Jian Li, Yi-Ting Tu, Sankar Das Sarma
We study many-body localization (MBL) in a nearest-neighbor hopping 1D lattice with a slowly varying (SV) on-site potential with . The corresponding non…
Negative intercept of the apparent zero-temperature extrapolated linear-in- metallic resistivity
Yi-Ting Tu, Sankar Das Sarma
We consider the well-known phonon scattering induced high-temperature linear-in- metallic resistivity, showing that a naive extrapolation of the effective linearity from high te…
Interacting quasiperiodic spin chains in the prethermal regime
Yi-Ting Tu, David M. Long, Sankar Das Sarma
Recent progress in the study of many-body localization (MBL) in strongly disordered interacting spin chains has emphasized the importance of distinguishing finite time prethermal b…
Role of many phonon modes on the high-temperature linear-in- electronic resistivity
Sankar Das Sarma, Yi-Ting Tu
We theoretically consider the possibility that phonons may be playing a role in the observed linear-in- resistivity in cuprates by focusing on the obvious question: How can phon…
Energetic comparison of exciton gas versus electron-hole plasma in a bilayer two-dimensional electron-hole system
Yi-Ting Tu, Seth M. Davis, Sage B. Brooks +1
We study the zero-temperature phase diagram of a symmetric electron-hole bilayer system by comparing the ground state energies of two distinct limiting cases, characterized by an e…
Wiedemann-Franz law in graphene in the presence of a weak magnetic field
Yi-Ting Tu, Sankar Das Sarma
The experimental work [J. Crossno et al., Science 351, 1058 (2016)], which reported the violation of the Wiedemann-Franz law in monolayer graphene characterized by a sharp peak of…
Localization spectrum of a bath-coupled generalized Aubry-André model in the presence of interactions
Yi-Ting Tu, DinhDuy Vu, Sankar Das Sarma
A generalization of the Aubry-André model, the non-interacting GPD model introduced in S. Ganeshan et al.,[ Phys. Rev. Lett. 114, 146601 (2015)], is known analytically to possess a…
Wiedemann-Franz law in graphene
Yi-Ting Tu, Sankar Das Sarma
We analyze a well-known experimental work [J. Crossno et al., Science 351, 1058 (2016)] which reported on the failure of the Wiedemann-Franz law in graphene at -$100\,\ma…
Avalanche stability transition in interacting quasiperiodic systems
Yi-Ting Tu, DinhDuy Vu, Sankar Das Sarma
Coupling a 1D quasiperiodic interacting system to a Markovian bath, we study the avalanche instability of the many body localized phase numerically, finding that many body localiza…
General properties of fidelity in non-Hermitian quantum systems with PT symmetry
Yi-Ting Tu, Iksu Jang, Po-Yao Chang +1
The fidelity susceptibility is a tool for studying quantum phase transitions in the Hermitian condensed matter systems. Recently, it has been generalized with the biorthogonal basi…
Rényi entropies and negative central charges in non-Hermitian quantum systems
Yi-Ting Tu, Yu-Chin Tzeng, Po-Yao Chang
Quantum entanglement is one essential element to characterize many-body quantum systems. However, the entanglement measures are mostly discussed in Hermitian systems. Here, we prop…
Non-Abelian fracton order from gauging a mixture of subsystem and global symmetries
Yi-Ting Tu, Po-Yao Chang
We demonstrate a general gauging procedure of a pure matter theory on a lattice with a mixture of subsystem and global symmetries. This mixed symmetry can be either a semidirect pr…
