Phase transitions out of quantum Hall states in moire bilayers
Senthil Todadri - Massachusetts Institute of Technology (MIT) - Department of Physics
Quantum Hall phases are the most exotic experimentally established quantum phases of matter.Recently they have been discovered at zero external magnetic field in two dimensional moire materials. I will describe recent work (with Xue-Yang Song and Ya-Hui Zhang) on their proximate phases and… -

Composite fermi liquids and non-commutative field theory
Senthil Todadri - Massachusetts Institute of Technology (MIT) - Department of Physics
The interplay between topology, strong correlations, and kinetic energy presents a new challenge for the theory of quantum matter. In this talk I will describe some recent progress on understanding a simple class of problems where these effects can all be analytically handled. I will first present… -
When topology meets strong interactions in quantum matter
Senthil Todadri - Massachusetts Institute of Technology (MIT) - Department of Physics
The study of strongly interacting quantum matter has been at the forefront of condensed matter research in the last several decades. An independent development is the discovery of topological band insulators. In this talk I will describe phenomena that occur at the confluence of topology and strong… -
Landau ordering and other phase transitions beyond the Landau paradigm
Senthil Todadri - Massachusetts Institute of Technology (MIT) - Department of Physics
I will discuss several examples of novel continuous phase transitions, primarily in 3+1-D, that are beyond the standard Landau paradigm of order parameter fluctuations. These provide non-trivial examples of deconfined quantum critical points. -
An Adventure in Topological Phase Transitions in 3 + 1-D: Non-abelian Deconfined Quantum Criticalities and a Possible Duality
Senthil Todadri - Massachusetts Institute of Technology (MIT) - Department of Physics
I will present recent results (with Zhen Bi) on novel quantum criticality and a possible field theory duality in 3+1 spacetime dimensions. We describe several examples of Deconfined Quantum Critical Points (DQCP) between Symmetry Protected Topological phases in 3 + 1-D. We present situations in… -

Interacting electronic topological insulators in three dimensions
Senthil Todadri - Massachusetts Institute of Technology (MIT) - Department of Physics
I will review recent progress in describing interacting electronic topological insulators/superconductors in three dimensions. The focus will be on Symmetry Protected Topological (SPT) phases of electronic systems with charge conservation and time reversal. I will argue that the well known Z2… -
Interacting topological insulators in three dimensions: classification and properties
Senthil Todadri - Massachusetts Institute of Technology (MIT) - Department of Physics
A fundamental open problem in condensed matter physics is how the dichotomy between conventional and topological band insulators is modified in the presence of strong electron interactions. In this talk I describe recent work showing that there are 6 new electronic topological insulators that have… -
3d boson topological insulators and quantum spin liquids
Senthil Todadri - Massachusetts Institute of Technology (MIT) - Department of Physics
I will discuss recent work on 3d Symmetry Protected Topological (SPT) phases of bosonic systems, and their implications for understanding the more exotic quantum spin liquid phases. First I will describe various characterizations of these 3d SPT phases, in particular their surface effective theories… -
Integer Quantum Hall Effect for Bosons: A Physical Realization
Senthil Todadri - Massachusetts Institute of Technology (MIT) - Department of Physics
A simple physical realization of an integer quantum Hall state of interacting two dimensional bosons is provided. This is an example of a "symmetry-protected topological" (SPT) phase which is a generalization of the concept of topological insulators to systems of interacting bosons or fermions…
