Exciting new phenomena that can be used in future quantum technology are produced by quantum effects that change the macroscopic behaviour of materials. This one day workshop focuses on cutting-edge experimental tools for the identification of unusual phases and their fundamental excitations. To demonstrate how exceptional material properties can be obtained by controlling electronic and magnetic properties through material design and by applying external stimuli like temperature, magnetic field, and pressure, we aim to bring together the most recent developments in quantum many body physics and materials science.
The Emergent Phenomena in Quantum Matter (EPQM) research group at the Department of Physical Sciences, IISER Kolkata is led by Siddhartha Lal. EPQM engages in theoretical research on various topics in the condensed matter physics of quantum matter, ranging from strongly-correlated electronic systems, quantum magnetism, topological phases of matter, non-Fermi liquids, unconventional superconductivity, many-particle entanglement and low-dimensional systems.
Vidhyadhiraja Sudhindra's research group works on strongly correlated electron systems employing analytical and numerical techniques of quantum many-body theory such as Green's functions approach, renormalization group approaches quantum Monte Carlo and slave particle techniques. They focus on issues of quantum criticality, Mott metal-insulator transition, Kondo physics, and non-equilibrium transport.
Kaushik Sen's research group strives to identify microscopic interactions and dynamics that essentially stabilize macroscopic quantum phases, such as high-Tc superconductivity, 2D electron gas, and quantum spin liquid states. Primarily, they use polarized Raman scattering to probe dynamics of various quasiparticles in both thin films and single crystals of quantum materials.
Chandra Shekhar Yadav
CS Yadav's research group at IIT Mandi works in strongly Correlated Electron Systems, Superconductivity, Magnetism, Topological phases, Multiferroics, Thermoelectricity etc.
Sumiran Pujari's research group is interested in various aspects of condensed matter theory.
Long-standing interests center around quantum magnetism, quantum phase transitions and algorithm design for quantum Monte Carlo of spin Hamiltonians. Recently, the band topology of semi metals is another area that they have been focusing on.
Deepshikha Jaiswal Nagar
Deepshikha's research group works on the experimental investigations of bipartite and multipartite entanglement in quantum critical systems-primarily, low dimensional magnets and high temperature superconductors via inelastic neutron scattering, thermal expansion, magnetic susceptibility and specific heat measurements. Single crystal growth of these materials, their deuteration for high signal to noise etc. compliments the above measurements.
Anil Shaji’s research group works on various questions at the interface of physics and information theory. Open quantum systems at various scales ranging from single quantum systems to condensed matter systems is one of the focus areas. Constructing a comprehensive understanding and mathematical description of non-Markovian dynamics in such systems is a problem that is being actively pursued by the group. Non-classical correlations, including but not limited to entanglement, in quantum systems is another area of interest. The group works on using such correlations to understand the reasons why mixed state quantum information processors can still solve certain computational problems exponentially faster than classical ones even in the absence of quantum entanglement. The role of these correlations in understanding the properties of low dimensional lattices and materials is another area of interest. Simulation of molecular systems and quantum field theories on small scale quantum information processors is also being pursued actively by the group. Other research interests include quantum limited metrology and sensing, quantum algorithms and machine learning etc.
Anil Jain joined the Solid-State Physics Division, Bhabha Atomic Reserach Centre, Mumbai, in 2004 after graduating from the 47th Batch of BARC Training School. His recent research focuses on spin correlations in low-dimensional quantum magnets using neutron scattering. He has used neutron scattering to investigate novel electronic ground states and associated physical phenomena in 3d and 4d transition metal oxides and studied the interplay of spin-orbit coupling, electron correlations, quantum fluctuations, and low dimensionality in such magnetic systems. Underpinning the experimental programme is the growth of single crystals by a variety of methods, including the floating-zone technique in image furnaces and flux growth.
T. Maitra’s group at the Department of Physics, IIT Roorkee is engaged in studying novel quantum materials using first principles based approaches as well as other numerical methods such as monte carlo etc. on model Hamiltonians. Research interests of the group is focused mainly on geometrically frustrated magnetic materials, strongly correlated electronic materials, magnetic order driven topological states in materials, 2D materials, multiferroics etc.
